As technology becomes increasingly advanced, the demand for reliable and long-lasting battery power has also escalated. AGM replacement battery provides a cost-effective and efficient solution for devices that are experiencing poor battery performance or have become outdated due to technology advancements.
What is an AGM battery?
AGM (Absorbent Glass Mat) battery is a type of lead-acid battery that utilizes a unique separator technology. The separator is a fiberglass mat that is placed between the positive and negative plates of the battery. This mat absorbs the electrolyte solution, which allows for a thinner separator and more efficient energy storage.
AGM batteries are known for their high-cycle life, robustness, and ability to maintain their performance in adverse conditions. They are commonly used in applications that require reliable backup power, such as uninterruptible power supplies (UPS) and medical devices.
Improved performance: AGM replacement battery typically offers improved performance over the original battery. They can provide higher capacities, longer runtimes, and faster charging capabilities.
Extended lifecycle: AGMs are designed to last longer than standard lead-acid batteries. They can withstand a higher number of charge/discharge cycles, resulting in fewer battery replacements.
Saving money: In some cases, replacing an AGM battery can be less expensive than purchasing a new device or upgrading to a higher-capacity battery.
Environmentally friendly: AGMs are recyclable and contain no harmful substances, making them an environmentally responsible choice.
Peace of mind: Knowing that your critical devices are backed up by a reliable power source can provide peace of mind during unexpected power outages or equipment failures.
How to choose an AGM replacement battery
When choosing an AGM replacement battery, it’s important to consider the following factors:
Application: Determine the intended use of the battery and choose a model that meets the specific requirements. For example, a UPS may require a higher capacity and faster charging capability than a medical device.
Voltage and capacity: Compare the voltage and capacity requirements of the device with the specifications of the replacement battery. Ensure that the new battery provides sufficient power for the device’s needs.
Physical dimensions: Check the physical dimensions and mounting requirements of the device to ensure that the new battery can be installed and fit into the designated space without problems. Sometimes customized batteries or adapters may be required due to differences in size or specifications.
Warranty: Consider the length and terms of the warranty offered by the manufacturer. A long warranty period can provide peace of mind in the event of battery failure.
Price: Factor in the cost of the battery, including any additional features or services offered by the manufacturer, when making your decision. Cost-effectiveness is an important factor, but don’t compromise on quality and performance.
Reliable Manufacturer:Choose a reputable manufacturer with a track record of quality products and customer satisfaction. Check online reviews and research different brands before making your selection.
Longevity: Choose a battery with a long expected lifespan to ensure that it will serve you for a considerable amount of time without requiring frequent replacements.
Environmentally friendly: If environmental concerns are important to you, choose a battery that is recyclable and made from sustainable materials. This will help reduce waste and protect the planet.

The “EU Batteries and Waste Battery Regulations”(hereinafter referred to as the “New Battery Law”) officially came into effect on August 17. The new regulations will have a profound impact on all aspects of the entire life cycle of the battery industry chain including custom lithium battery pack design, production, and recycling in the EU.
Among them, the release of battery passport information has particularly attracted industry attention. According to the battery passport concept proof released by the Global Battery Alliance (GBA), product information has four important components: battery information (Battery), material information (Material), environmental social responsibility and corporate governance information (ESG), data source information (Data).
So, will the information required to be released by the battery passport bring intellectual property protection challenges to custom lithium battery pack design?
Extending to the impact on battery design, the application of battery passport will put forward new requirements for battery design; Will the battery cell design configuration in the European market tend to be diversified or more single; What changes can companies make on the R&D side to cope with this? Meet new challenges and seize new opportunities.
At the same time, the battery passport contains information about some manufacturing segments, which poses more challenges or opportunities for battery production; how equipment companies should help battery companies improve their carbon footprint is currently a hot topic in the industry.
Recently, Hu Ke, general manager of Elacode Europe, had an in-depth discussion and communication with Li Zhe, associate professor and doctoral supervisor of Tsinghua University, and Yang Rukun, chairman of Jiyang Intelligent, on the application of battery passports in the new battery law in the field of custom lithium battery pack design and battery manufacturing. This helps the industry gain a deeper understanding of the impact of battery passports on the industry and how companies can respond to future opportunities and challenges.
The impact of new battery law on battery design
Will the information required to be published in the battery passport bring intellectual property protection challenges to battery design?
According to several Pilot (verification) cases on battery passports given by GBA (Global Battery Alliance, International Battery Alliance), some information related to the design of battery packs and battery cells is indeed announced, such as the design of the entire battery pack. Energy grade, the quality of key metals used in them, etc.
However, judging from the current three Pilot (verification) cases, the published information is relatively information that needs to be disclosed in the process of supplying battery cells or custom lithium battery pack to vehicle companies. The GBA Battery Passport does not require manufacturers to publish confidential information, such as trace amounts of metal doping, unique processes used in battery design and manufacturing, etc. Therefore, the current scope of battery passport disclosure will not affect the intellectual property protection of battery companies.
The Pilot sample of Battery Passport contains some battery performance information, such as cycle life, but some companies choose not to publish it. What are the reasons? Can share the latest research results of forward R&D and simulation-driven design in battery life prediction and failure analysis?
The issue of battery cycle life is a topic of great concern. In the case of the Battery Passport Pilot, Tesla is one of the few companies to announce battery cycle life. However, the cycle life figures it publishes are relatively low, even more so compared with the battery life figures claimed by some domestic vehicle companies. Much lower than the figures for energy storage batteries.
In fact, judging from the actual life of power batteries and energy storage batteries, the distribution range of cycle life is quite wide. A typical private car is charged and discharged twice a week, and its service life is about 10 years. In this case, the power battery is not required to have a cycle life of more than 5,000 times.
In contrast, energy storage batteries are required to have a cycle life of close to 7,000 to 12,000 times within a 10- or even 20-year warranty period. This wide range of life is mainly affected by the construction of the battery, the materials used, and key processes.However, many companies face specific pressures in practical applications, especially in energy storage batteries.
The fiercely competitive energy storage market forces companies to seek breakthroughs in low-cost, long-life batteries. This has led to some high cycle life figures on the market, sometimes as high as 14,000 to 12,000 cycles. However, many companies have found that under laboratory conditions, There is a gap between observed longevity and user expectations.
As for why some companies choose not to publish performance information such as cycle life, firstly, there are currently no mandatory regulations. Secondly, it may depend on the promotion of battery passports among companies. To solve this problem, some solutions have emerged in the long-life battery design and manufacturing field.
Regarding the basic materials and formulas of batteries, there are already formulation solutions for long-life energy storage batteries. These solutions help increase the cycle life from two or three thousand times to the expected five or six thousand cycles of iron lithium. In addition, some new electrolytes, additives, lithium salts, and other solutions also provide more possibilities for custom lithium battery pack design and manufacturing. These solutions mainly involve using new additives, material selection, and process improvements.
In this process, modeling and simulation methods play an essential role in developing long-life batteries. Modern battery models can already simulate the internal aging mechanism of the battery so that the impact of materials, formulations, design, and manufacturing characteristics on life can be predicted from a mechanistic perspective.
In addition, reasonable modeling methods can reduce the need for long-life multiple-cycle experiments and accelerate the battery development process oriented to life indicators, thus significantly shortening the development cycle.
In short, the issue of battery cycle life involves the broad application of power and energy storage batteries, which differs from a single application requirement, making the cycle life distribution range wider. When enterprises face competition and market pressure, seeking long-life, low-cost battery solutions is critical. Modeling and simulation methods play an essential role in this process, accelerating the process of battery research and development.
What new requirements will the application of battery passport bring to battery design?
Battery passport requires disclosing battery materials, energy, life, and other information, which poses many challenges during the custom lithium battery pack design stage. To achieve goals such as vehicle driving range, it is necessary to increase the energy density of batteries under the constraints of quality and capacity, which is also the focus of enterprises. At the same time, the use of environmentally friendly materials and cost reduction are also design considerations, among which cobalt-free technology has become a representative innovation in the industry.
The European Battery Act has attracted widespread attention and requires the local recycling of battery materials, highlighting the importance of battery sustainability. This impacts battery material selection and manufacturing processes, requiring sustainability considerations to be considered throughout the entire life cycle. Batteries have a long life cycle, and sustainability needs to be viewed from design and manufacturing to multiple uses, disassembly, and recycling. For example, the welding and glue inside the battery are not friendly to disassembly, so design solutions for easy recycling will bring about design changes.
In addition to performance and cost, today’s businesses must consider sustainability an important metric. Launching the battery passport will increase the transparency of battery cell design and promote cooperation and experience sharing within the industry, thereby comprehensively considering energy efficiency, environmental impact, material sources, and life cycle management in the design and achieving a more sustainable battery design.
Will the battery cell design configurations in the European market tend to be diversified or more uniform?
There has long been a structural controversy in the battery field, especially in large-scale batteries. People often hear discussions about the Unified Cell (unified cell) or 46 system. The area of energy storage batteries is relatively harmonious, with most batteries adopting a square winding hard shell system, especially the 71173 standard.
However, the diversity of structures is even more significant when it comes to power batteries. The structures of power batteries include square rolls, soft bags, blades cylinders, etc., with different shapes. Although the square roll configuration is still the mainstream, the other three structures also have their advantages. Especially for large cylindrical structures, such as the 46 series, the specifications continue to expand from 80, 95, 120, etc., and the capacity of a single battery develops from 3Ah to more than 30Ah or even higher. This structure is famous in the European market, and some OEMs support related power battery companies to create large cylindrical configurations.
The reason why the sizeable cylindrical configuration is popular is mainly reflected in two aspects: first, it continues the high efficiency of the winding production method; Secondly, when using the twisted cylindrical structure, it can better control the silicon content, The influence of factors such as high volume expansion materials on internal stress.
On the market, various configurations go hand in hand. Although some European and American companies have invested in Chinese power battery companies in the early stages, such as Volkswagen and Mercedes-Benz, there has yet to be a clear winner. Some companies have chosen soft-pack configurations, while others are moving towards large cylinders. Some companies have even proposed the concept of Unified Cell, which has the same appearance but different internal structure. This approach can reduce production diversity, such as coil production, casings, mechanical parts, etc.
To sum up, the choice of battery structure is still changing dynamically, and there is no clear winner yet. Similar to the situation in the Chinese market, this “let the bullets fly for a while” problem also exists in the European market. European and American companies’ investment and development strategies in Chinese battery companies and structure selection show that the market has not yet formed a clear consensus.
What changes can companies make on the R&D side to cope with new challenges and seize new opportunities?
The future development of the power battery industry will mainly focus on the two themes of reducing costs and improving efficiency. This is not a simple relationship from zero to one, but a process from one to one hundred about how to do better and faster based on the existing foundation. China is at the forefront in this regard, and the battery industry has entered a stage of high-quality development with an absolute size, slowing relative growth, but still full of vitality.
This also means the battery industry will maintain solid growth for some time. At this stage, accelerated development and cost reduction are crucial to the fate of the enterprise.
Among them, intelligent technology will bring revolutionary changes in the battery design and manufacturing field. Traditional battery design methods usually involve diverse sample preparation and testing processes, which wastes battery materials, staffing, and time.
Is there a new battery design method and corresponding design tools that can significantly shorten the design cycle from the traditional one year or even two years to a few weeks or months? A similar situation exists in battery manufacturing. Various wastes in the manufacturing process, such as yield issues, energy consumption, emissions, etc., must be addressed. Even when exploring new configurations, such as tab welding for large cylindrical batteries, long pole blades, etc., these problems still need to be faced.
Therefore, intelligent new design and manufacturing technologies will be the key to solving these challenges. From a design perspective, innovative technology can significantly shorten the design cycle and reduce waste. On the manufacturing side, intelligent technology can optimize factory management, improve production efficiency, reduce energy consumption and emissions, and even move towards the goal of green and zero-carbon factories.
In short, as China’s battery industry is about to enter a stage of high-quality development, intelligent technology will be a powerful tool to help companies accelerate growth and reduce costs. The introduction of this technology will have a positive impact in the field of battery design and manufacturing, pushing the industry towards a more efficient and sustainable direction.
The impact of the new battery law on battery manufacturing
The battery passport contains information about some manufacturing segments. Does it pose more challenges or opportunities for battery production?
The newly promulgated battery passport regulations, involving battery labels and manufacturing information, provide a situation where opportunities and challenges coexist. Implementing a battery passport will help standardize the entire battery manufacturing, use, and recycling process and improve the regulation and efficiency of battery use. This will help monitor various parameters during custom lithium battery pack use, improving battery quality. This will have positive significance for regulating and developing the entire industry.
Are there any obvious differences in carbon emission performance between the front, middle and back stages of battery production?
Carbon emissions are relatively evenly distributed among the front, middle, and rear sections. The energy consumption involved in the entire manufacturing process, such as heating, cooling, chemical formation, or liquid injection, consumes energy. The continuity of the battery manufacturing process, from material design to manufacturing process, requires the control of energy consumption. Therefore, achieving improvements in carbon footprint requires a concerted effort from both battery materials and manufacturing technologies.
Technical approaches to improve carbon footprint
Manufacturing technology has a significant impact on carbon footprint, especially in terms of improvements in manufacturing processes and processes. In a short time, energy consumption can be reduced by improving manufacturing processes and processes. At the same time, in the long term, it is necessary to optimize the entire manufacturing process, starting from the battery design and material system. For example, changing and optimizing the battery material system can reduce the energy consumption of the manufacturing process and thereby improve the carbon footprint.
The help and role of lithium battery equipment companies
From the perspective of custom lithium battery pack equipment manufacturers, equipment plays a vital role as executors and controllers in battery manufacturing. By establishing digital control and data systems, the equipment can help manufacturers optimize the manufacturing process and improve quality while also helping to solve the challenges of the new battery passport regulations.

Lithium (Li), as the charge carrier in traditional li ion customized battery packs and emerging lithium metal batteries, has always been an indispensable medium to ensure battery operation. However, battery energy, longevity, and safety improvements are urgently needed in various applications, including electric vehicles and grid energy storage. Currently, inactive lithium (dead lithium) in the form of a solid electrolyte interface phase (SEI) and metallic lithium that loses contact with the electrode and loses the conductive path are considered to be the main reasons for capacity fading and insufficient life. It depends largely on the nature of SEI on the negative electrode surface for these unfavorable factors.he volume change of lithium during cycling causes the SEI to rupture, fresh lithium is exposed to the electrolyte again to form a new SEI. Such repeated damage/repair of the SEI makes the previously used strategies to improve SEI stability unavailable. In addition, the potential relationship between SEI film fragments (dead SEI) and metallic lithium due to electrode disengagement and loss of conductive pathways is unclear, making clarifying strategies to suppress dead lithium to prevent battery failure more challenging.
In view of this, the team of Professor Tao Xinyong of Zhejiang University of Technology and Professor Lu Jun of Argonne National Laboratory (co-corresponding author) quantified the Li2O content in the SEI layer based on the recent understanding that Li2O dominates SEI on lithium metal anodes. More importantly, the team revealed the correlation between SEI film fragmentation and dead lithium and showed that lithium loss in the SEI and dead lithium fragmentation are major causes of expected performance degradation in lithium metal batteries.
Based on such findings, the team proposed a method to reduce SEI fragment content through the redox reaction of iodine mediator (I3-/I-), which can effectively activate electrochemistry in dead SEI and Inactive lithium. The proposed Li2O transfer from the dead SEI to the newly exposed lithium surface not only effectively eliminates the accumulation of dead SEI and lithium metal fragments during lithium deposition/stripping cycles but also significantly suppresses the highly active metal-induced electrolyte decomposition in batteries.
The team used biomass materials as carbon sources to prepare carbon-loaded iodine capsules (ICPC) and found that I3-/I- spontaneous redox can effectively restore dead lithium to compensate for lithium loss. Notably, the deactivated lithium in LiO of dead SEI and deceased lithium metal fragments are transferred to the high-voltage cathode and subsequently recycled to compensate for the loss of lithium, thereby significantly improving the cycle reversibility of lithium metal batteries. The electrochemical performance shows that lithium metal total cells based on limited li ion customized battery packs exhibit ultrahigh performance (1000 cycle life and high Coulombic efficiency of 99.9%); using this strategy to match LiFePO4 (LFP) and LiNi0.8Co0.1Co0.1Mn0 .1O2 (NCM811) and other commercial cathode-assembled button and pouch batteries have shown very encouraging cycle performance and ultra-high efficiency. Therefore, this strategy opens up new avenues for mitigating the capacity fading caused by inactive lithium supply of lithium metal batteries and improving their cycle life, and also for other anode materials challenged by dead SEI and dead lithium, such as silicon, tin, alloys, etc., providing the possibility of large-scale application. Related research results, “Rejuvenating dead lithium supply in lithium metal anodes by iodine redox,” were published in Nature Energy.

Currently, lithium-ion batteries are used in industrial equipment in various industries. Since there are no fixed custom lithium battery pack specifications and size requirements in various industrial fields. Therefore, there are no conventional lithium batteries for industrial equipment and they all need to be customized. So how long does it take to make li ion customized battery packs?
Under normal conditions, it takes about 15 days to custom lithium battery pack;
Day 1: After receiving the order requirements, the R&D personnel evaluate the order requirements, quote samples and establish customized product projects.
Day 2: Selection and circuit design for product battery cells
Day 3: Make a structural drawing and confirm with the customer, and conduct business negotiations
Day 4: Start material selection, BMS protection board design, battery assembly, cycle charge and discharge, circuit and other tests and debugging verification
Then the packaging, warehousing, quality inspection, outbound delivery, and transportation to the customer are carried out, and the customer conducts sample testing and other work. Under normal circumstances, it takes about 15 working days.
Our lithium battery assembly is not like a small workshop where unknown batteries and BMS protection boards are directly packaged in series and parallel and shipped without testing and verification. This kind of battery is generally a price war. The price of the battery is very low and there is no after-sales guarantee. Basically, it is a one-time business. We will conduct strict testing on all materials, including battery cells, BMS, power harnesses and plugs. All materials must pass the inspection before they can be used to make li ion customized battery packs .

Part of RV ownership is maintenance. In this video, we replace our motorhome’s 4 house batteries and talk about some things we’ve learned about battery maintenance. We hope that you can learn from our mistakes to get the most out of your RV’s battery life. We replaced 4 6-volt golf cart batteries with 4 new 6-volt golf cart batteries. We did a lot of research to decide what batteries to buy and we learned a few things along the way.
Tips for Replacing Your RV’s House Batteries
Study Your Battery Bank Before You Start! Before you begin removing your old house batteries, be sure that you take pictures of the compartment so that you can see how everything is connected. Some RV battery bays are pretty tight and it can be difficult to see everything in the back, so be sure to snap some photos in the back of the bay as well. We’d also suggest drawing a simple diagram to remind you of how the batteries are positioned, where the positive and negative terminals are located and which cables connect to what so that you can be sure all of your cables will reach what they need to.
Decide What Type of Battery is Right For You There are three main types of batteries used for RV house batteries: traditional lead acid (also called flooded cell batteries), AGM (which stands for Absorbed Glass Mat or sometimes Absorbent Glass Mat depending on where you look), and Lithium. The type of batteries you choose can be based on price, space, power needs and how you use your RV. Whichever you decide to go with, all of your batteries should be the same type, size and age. Be consistent.
Save Money By Recycling Retailers today will charge a “core” fee when you are buying batteries. This is a recycling fee that is placed on every battery. We avoided this fee by giving them our old batteries when we bought the new ones.
Not All Batteries Are Created Equal Do your research ahead of time to determine what will be right for your needs. RV House Batteries are available in 6-volt and 12-volt and in a wide variety of amperages. Know what you currently have and how that works out for you. And spend some time doing some research online to narrow down what you are looking for so you aren’t wasting gas running all over town. And remember, 6-volt batteries will be connected differently than 12-volt batteries. So, again, pay close attention to how your batteries are connected.
Using Our Battery Quick Fill System to Top Off Our House Batteries
If You Choose Lead Acid Batteries You will need to maintain the level of distilled water in your batteries. This can be a pain in the butt if some of your batteries are difficult to access. Since 2014, we have used a battery quick fill system to easily and quickly add distilled water to our house batteries. The filling tubes stay connected at all times. When it’s time to check the water level, we connect the end of that tube to our hand pump which has another tube that we put down into the bottle of distilled water. All we have to do is squeeze the pump a a few times. It tops off all of our house batteries simultaneously and will not allow them to overfill. It is really super simple and we highly recommend it. As long as we have lead acid batteries in our RV, we will use a battery quick fill system! Here’s one like ours if you’d like to get one for yourself: Flow-Rite RV2000 RV Edition 2 Battery Kit. (We have 2 of these since we have 4 6-volt house batteries.)
Types of RV House Batteries
Lead Acid Batteries Also called “flooded cell” batteries, lead acid batteries are the least expensive option for replacing the house battery bank in most RVs. They are also the most common type of battery you’ll probably find in most campers. The price is nice (especially when you are replacing multiple batteries), but there are a few downsides to lead acid batteries. They require more maintenance than the other types of batteries. As we mentioned above, you have to keep a close eye on the fluid levels of these batteries. Low fluid levels can affect performance and may significantly shorten your battery’s life. With the quick fill system we suggest above this is super easy to do, but you have to remember to perform this maintenance regularly.
You also want to keep an eye on the charge level of your lead acid batteries. We’ve read that allowing the battery charge level to drop below 50% will potentially damage the battery and shorten its life. This isn’t a problem when you are plugged into shore power, but be very mindful of your charge levels if you are boondocking and be sure to check on your batteries regularly when your RV is in storage! Lead acid batteries will lose their charge in storage even if you have disconnected them.
AGM Batteries Absorbed Glass Mat batteries are sealed and do not require you to add distilled water. So they require a little less maintenance than lead acid batteries, but they are also more expensive. You still need to monitor your charge levels just like you would with lead acid batteries. Just like their lead acid cousins, AGM batteries will lose their charge in storage even when disconnected.
We’ve read reports that say that AGM batteries may recharge more quickly than lead acid, but they may also be more sensitive to overcharging. Some articles we read also said that AGMs might be more sensitive to temperature changes than their lead acid counterparts.
Lithium Batteries The newest option (and the technology that seems to be quickly changing at the moment) is lithium. Lithium batteries are a lot more expensive than the other options. Traditionally, they are sized completely differently than most RV house batteries and have been known to be very sensitive to temperature. However, they are lighter in weight (which is always a good thing in RVs!), more powerful, and can use up more of their charge without risking damage to the life of the battery.
We’ve read that the latest chemistries in lithium batteries for RVs are less sensitive to temperature changes and allow the batteries to maintain their charge in storage for up to a year! When we were doing our research, we came across some new lithium batteries that were sized just like the 6-volt golf cart batteries (GC2) we currently have, so they would have worked easily with our existing battery location and brackets.
Tips for Maintaining Your RV’s Batteries
Keep An Eye On the Water Levels We can’t stress this one enough! If you have lead acid batteries, like us, then you have to maintain the distilled water levels of your batteries. Start checking those water levels as soon as you buy your RV. Even brand new RVs can have batteries without sufficient water. (Maybe that particular RV has been on the lot for a little while?) Never assume what your RV has been through before you found it. Be consistent about checking the fluid levels and maintain them easily with a Flow-Rite battery quick fill system. (Have we told you how much we love ours? It has saved us a ton of head bumping and unmentionable language over the years!) 🙂
Use a Trickle Charge If you have access to a standard 110 power plug, you can use a Camco 30amp to 15amp Adapter or a Camco 50amp to 15amp Dogbone Adapter to trickle charge your RV’s house batteries while it is in storage. However, do not assume that it is charging just because you have it plugged in. If the power to your storage area fails for any reason, your RV batteries may end up discharging instead of charging. This happened to us twice. So always go back within 24 hours after you plug in to trickle charge to check on your batteries. We’ve read that your batteries should be fully charged within that 24 hours, so you’ll want to unplug them and disconnect them at that point anyway. (especially if you do not have a good energy management system to keep your batteries from overcharging)
Don’t Assume Anything We have learned this the hard way! The batteries are the heart of your RV. There is nothing worse than getting ready for a camping trip only to find that your batteries are low or dead. Be proactive in maintaining your batteries and you will never be surprised. This is especially true for part-time or seasonal RVers. Be sure you check on your batteries regularly. Don’t assume anything when it comes to them.
Disconnect the Batteries When Not Using or Charging If you are storing your RV, even for a few days, and you will not be trickle charging the batteries, be sure to disconnect them. For our travel trailer, this meant physically disconnecting the battery cable. In our motorhome, it means that we set the inside battery button to “Store” and the chassis battery switch inside our battery bay to “Off”. We’ve also learned to check to make sure the Inverter/Charge Controller is turned off before we set these battery switches. But remember, lead acid and AGM batteries will still lose some of their charge even when they are disconnected. So be sure to come back to check on them at least every couple of weeks.
Use Your RV As Often As Possible! RV batteries like to be used, so try to get out and go camping as often as possible (as if you need another excuse, right?). It’s also easier to remember to check and maintain your batteries when you are using it than when it is in storage away from you.
Battery capacity (how many amp-hours it can hold) is reduced as temperature goes down, and increased as temperature goes up. This is why your car battery dies on a cold winter morning, even though it worked fine the previous afternoon. If your batteries spend part of the year shivering in the cold, the reduced capacity has to be taken into account when sizing the system batteries. The standard rating for batteries is at room temperature 25 degrees C (about 77 F). At approximately -22 degrees F (-30 C), battery Ah capacity drops to 50%. At freezing, capacity is reduced by 20%. Capacity is increased at higher temperatures – at 122 degrees F, battery capacity would be about 12% higher.
Wide temperature variations
Battery charging voltage also changes with temperature. It will vary from about 2.74 volts per cell (16.4 volts) at -40 C to 2.3 volts per cell (13.8 volts) at 50 C. This is why you should have temperature compensation on your lead-acid battery charger or charge control if your batteries are outside and/or subject to wide temperature variations.
Internal temperature of a battery
Thermal mass means that because they have so much mass, they will change internal temperature much slower than the surrounding air temperature. A large insulated battery bank may vary as little as 10 degrees over 24 hours internally, even though the air temperature varies from 20 to 70 degrees. For this reason, external (add-on) temperature sensors should be attached to one of the POSITIVE plate terminals, and bundled up a little with some type of insulation on the terminal. The sensor will then read very close to the actual internal battery temperature.
Battery life reduces at higher temperatures
Even though battery capacity at high temperatures is higher, battery life is shortened. Battery capacity is reduced by 50% at -22 degrees F – but battery LIFE increases by about 60%. Battery life is reduced at higher temperatures – for every 15 degrees F over 77, battery life is cut in half. This holds true for ANY type of lead-acid battery, whether sealed, Gel, AGM, industrial or whatever. This is actually not as bad as it seems, as the battery will tend to average out the good and bad times.
One last note on temperatures – in some places that have extremely cold or hot conditions, batteries may be sold locally that are NOT standard electrolyte (acid) strengths. The electrolyte may be stronger (for cold) or weaker (for very hot) climates. In such cases, the specific gravity and the voltages may vary from what we show.
Now we have launched a low temperature battery, HiMASSi Smart & Temp battery, which supports charging at -31 ℉.
