Why Lithium Iron Phosphate Batteries Are The Best Way To Power Your Floor Machine

Floor-Machines-with-Lithium-Battery

Floor-Machines-with-Lithium-Battery

Lithium batteries are making their way into the Floor Cleaning market and for good reason. If you look at all of the benefits, they are hands-down the best solution to power your floor cleaning machines. Learn why below:

LIFE

Probably the most well-known and obvious benefit is significantly longer life. Lithium iron phosphate (LiFePO4) batteries will provide 5 – 10 times more cycles than lead-acid batteries. This means, you aren’t replacing your batteries every 2-4 years. And, replacing lead-acid batteries is not a fun task; first there is downtime to do the battery replacement, then there is the heavy lifting to remove old batteries and install new batteries. Finally, there is the disposal of the spent batteries.

PRODUCTIVITY

Another major benefit is the runtime or range. There are a few reasons LiFePO4 batteries can, and do, provide increased runtime over lead-acid batteries.

1. The main reason is that a lithium battery provides the full rated capacity, regardless of the rate of discharge. Lead-acid batteries are typically rated at the 5-hour or 20-hour rate, which are based on constant current, laboratory-tested, and low rates of discharge.

For example, a 200Ah (based on the 20-hr rate) lead-acid battery will provide 200Ah if it is run at a constant current of 10A for 20 hours. However, that same battery may provide only 135Ah if it is run at a constant current of 75A for 1.8 hours.

With lead-acid batteries, as the rate of discharge increases, not only does the runtime decrease but the overall size of the fuel tank decreases.

In a real application, the current is never constant, in fact, it varies continuously and often significantly. It is unpredictable. So with a lead-acid battery, you are never really getting the published battery capacity, in a floor machine.

With a lithium iron phosphate battery, the fuel tank remains the same size regardless of the state of discharge. A 200Ah battery will provide 200Ah whether it is discharged at 10A or 100A. The battery will always deliver its published capacity.

2. Another reason LiFePO4 batteries provide more runtime than lead-acid batteries, is the capacity degradation over the life of the battery is slow and minimal.

Traditional wet lead-acid batteries typically provide around 80% capacity when brand new. They work up to their full capacity and remain there for a couple hundred cycles and then decline over the next couple hundred cycles. AGM or Gel lead-acid batteries will provide their full capacity when brand new and steadily decline right away. Some Gel batteries will maintain their full capacity for a few hundred cycles but then rapidly decline.

Lithium iron phosphate batteries provide full rated capacity immediately and continue to do so for about 1000 cycles, with a slow decline to 80-90% capacity between 1000 to 2000 cycles.

3. Lithium batteries charge quickly and can be opportunely charged without damaging the battery. This can significantly extend the range of your LiFePO4 battery per shift.

Increased runtime, means increased productivity!

POWER

Lead-acid batteries provide full power for a relatively short period of time because the voltage declines steeply during usage. Lithium iron phosphate batteries provide full power throughout usage. This means, your floor cleaning equipment has full power throughout its shift.

CONVENIENCE

How convenient are lithium batteries? Very. No maintenance, no adding water, no cleaning acid residue from cables, connections, battery tops and equipment. No replacements, or at least not for many years, and easy installation due to being incredibly light compared to lead-acid batteries.

ROBUST

Lithium iron phosphate batteries are difficult to damage. They can’t be over-charged because the Battery Management System protects against that. Unlike lead-acid batteries, if they are under-charged or left in a partial state of charge, they will not be damaged.

SAFETY

Lithium iron phosphate batteries are safe. Not all lithium chemistries are the same. LiFePO4 are an inherently safe chemistry. They produce a fraction of the heat generated by other lithium chemistries, due to their structural stability. Not to mention, they eliminate exposure to harmful gases that are continuously vented from lead-acid batteries.

COST

Lithium iron phosphate batteries offer great savings compared to lead-acid, between 20-50%, when you consider the total cost of ownership. Although the upfront cost of lithium is higher, the areas of saving are numerous. Reduced maintenance, battery replacement, labor and charging costs all add up to substantial savings. The lifetime cost is less than lead-acid and we’ve done the math to prove it!

Energy Storage: Global Capacity Predicted To Surge By A Third Every Year In 2020s

Battery-Storage-Projects

The consultancy predicts that US and China will drive global growth in cumulative energy storage capacity, which should top 740GWh by the end of the decade

Energy storage is poised for a decade-defining boom, with capacity set to grow by almost a third worldwide every year in the 2020s to reach around 741GWh by 2030, according to analyst Wood Mackenzie.

The firm’s latest forecasts for the burgeoning sector released on Wednesday point to a 31 per cent compound annual growth rate in energy storage capacity in the 2020s.

Growth will be concentrated in the US, which will make up just under half of global cumulative capacity by 2030, at 365GWh, the analysis predicts, while front-of-the-meter (FTM) energy storage will continue to dominate annual deployments, accounting for around 70 per cent of global capacity additions to the end of the decade.

The US FTM market is set to surge through 2021 due to significant short-term resources planned before slowing slightly through 2025. Beyond 2025, growth will become steadier as wholesale market revenue streams grow and utility investment is normalised, the report adds.

In particular, utility resource planning in the US is set to take a front seat for deployments over the coming decade, it says, in line with major recent shifts in utility approaches to renewables and storage, with the majority of utilities dramatically shifting planned resources towards renewables and storage due to cost and state-driven clean-energy goals.

“We note a 17 per cent decrease in deployments in 2020, 2GWh less than our pre-coronavirus outlook,” said the consultancy’s principal analyst Rory McCarthy. “We expect wavering growth in the early 2020s, but growth will likely accelerate in the late 2020s, to enable increased variable renewable penetration and the power market transition.”

Just behind the US in energy storage deployment, China is expected to see exponential growth in storage capacity, accounting for just over a fifth of global cumulative capacity at 153GW by 2030, according to Wood Mackenzie.

Europe’s growth story, on the other hand, is expected to be slower than its global counterparts, with the UK and Germany continuing to dominate the continent’s FTM market out to 2025, with the markets in France and Italy also opening up.

Wood Mackenzie senior analyst Le Xu emphasized that “storage holds the key to strong renewables growth.”

“The question is whether storage can capture stable long-term revenue streams,” she added. “Low-cost and longer duration storage can increasingly out-compete coal, gas and pumped hydro, enabling higher levels of solar and wind penetration. However, most lithium-ion energy storage systems economically max out at 4 to 6 hours, leaving a gap in the market.”

China’s CATL Poised To Overtake LG Chem As Top EV Battery Maker

EV-Battery-3.2v-100ah-200ah-280ah

EV-Battery-3.2v-100ah-200ah-280ah

Global competition for the world’s top spot for the manufacture of rechargeable batteries is getting fiercer as China is stepping up efforts to overtake its South Korean rival in the fast-growing electric vehicle market, Koreainvestors.com reports.

According to market research firm SNE Research on Oct. 5, South Korea’s LG Chem Ltd. maintained its market lead with 15.92 GWh of battery capacity supply in the first eight months of this year, accounting for 24.6% of the global EV battery market.

China’s Contemporary Amperex Technology Co. (CATL) came in second with 15.54 GWh, or 24% of the global market, followed by Japan’s Panasonic, whose market share stood at 19.2%.

Korea’s two other EV battery makers — Samsung SDI Co. and SK Innovation Co. — ranked fourth and sixth with 6.3% and 4.2%, respectively.

Data showed China’s CATL is swiftly closing in on market leader LG Chem. In July, LG Chem’s market share was 1.3 percentage points higher than CATL’s.

“LG Chem was able to keep its market leader position in the first half as the Chinese EV market shrank due to the coronavirus pandemic. But with the gradual recovery of the Chinese market since July, China’s battery makers are quickly narrowing the gap with their Korean rivals,” said a battery industry official.

Electric vehicles sold in China reached 83,000 units in August, more than half the global EV sales of 163,000 units.

China’s CATL poised to lead global market

CATL, which takes up 50-60% of the Chinese battery market, aims to expand its presence in Europe by building a plant in Germany and forging a partnership with Daimler AG.

Analysts said Chinese EV battery makers, on the back of strong government support, could overtake their Korean rivals in the near future. The Chinese government recently announced that it will extend state subsidies to its battery makers until the end of 2022. Such subsidies were scheduled to be phased out by the end of 2020.

Energy market researcher BloombergNEF predicts Chinese manufacturers will take the top spot in the global supply of EV batteries by the end of this year, leaving their Korean and Japanese rivals behind.

Korean companies are also facing competition from smaller rivals in Europe, where the growing EV market has helped LG Chem and other Korean battery makers gain ground in the global market.

Crowded EV battery market

According to foreign media reports, Northvolt AB, a Swedish battery developer and manufacturer, recently raised 600 million euros (820 billion won) in investment funding, in which German automaker Volkswagen also participated.

With the raised funds, Northvolt is known to be expanding its annual battery production capacity in Europe to 150 GWh by 2030.

Electric vehicle makers are also joining the race.

At its annual Battery Day on Sept. 22, Tesla Chief Executive Elon Musk said the company will make next-generation batteries for its electric cars in-house to cut costs.

The company said its battery production will rise to 100 GWh a year by 2022, similar to LG Chem’s annual output capacity for this year.

Why Can’t The Maximum Voltage Of A Lithium-ion Battery Exceed 4.2V?

Lithium-Ion-Battery

The voltage of a lithium-ion battery is determined by the electrode potential. Voltage, also known as potential difference or potential difference, is a physical quantity that measures the energy difference of electric charges in an electrostatic field due to different potentials. The electrode potential of lithium-ion batteries is about 3V, and the voltage of lithium-ion batteries varies with different materials.

For example, a general lithium-ion battery has a nominal voltage of 3.7V and a full-charge voltage of 4.2V; a lithium iron phosphate battery has a nominal voltage of 3.2V and a full-charge voltage of 3.65V. In other words, the potential difference between the positive electrode and the negative electrode of a lithium-ion battery in practical use cannot exceed 4.2V, which is a requirement based on material and use safety.

Lithium-Ion-Battery

If the Li/Li+ electrode is used as the reference potential, μA is the relative electrochemical potential of the negative electrode material, μC is the relative electrochemical potential of the positive electrode material, and Eg, the electrolyte potential range, is the difference between the lowest electron unoccupied energy level and the highest electron occupied energy level. So the maximum voltage of the lithium-ion battery is determined by μA、μC、Eg.

The difference between μA and μC is the open-circuit voltage (the highest voltage value) of the lithium-ion battery. When this voltage value is in the Eg range, the normal operation of an electrolyte can be ensured. Normal operation means that the lithium-ion battery moves back and forth between the positive and negative electrodes through the electrolyte, but does not undergo oxidation-reduction reactions with the electrolyte, So as to ensure the stability of the battery structure. The electrochemical potential of the positive and negative materials causes the electrolyte to work abnormally in two forms:

  1. When the electrochemical potential of the negative electrode is higher than the lowest electron and unoccupied energy level of the electrolyte, the electrons of the negative electrode will be captured by the electrolyte, and the electrolyte will be oxidized, then the reaction product will form a solid-liquid interface layer on the surface of the negative electrode material particles. As a result, the negative electrode may be damaged.
  2. When the electrochemical potential of the positive electrode is lower than the highest electron-occupied energy level of the electrolyte, the electrons in the electrolyte will be captured by the positive electrode and oxidized by the electrolyte. Then the reaction product forms a solid-liquid interface layer on the surface of the positive electrode material particles, resulting in the positive electrode may be damaged.

However, the possibility of damage to the positive or negative electrode is due to the existence of the solid-liquid interface layer, which prevents the further movement of electrons between the electrolyte and the positive and negative electrodes, and instead protects the electrode material.

That is to say, the lighter solid The liquid interface layer is protective. The premise of this protection is that the electrochemical potential of the positive and negative electrodes can slightly exceed the Eg interval, but not too much.

For example, the reason why most of the current lithium-ion battery anode materials use graphite is that the electrochemical potential of graphite related to Li/Li+ electrodes is about 0.2V, which slightly exceeds the Eg range (1V~4.5V), but because of its protective properties, the solid-liquid interface layer prevents the electrolyte from being further reduced, thus stopping the continuous development of the polarization reaction.

However, the 5V high-voltage cathode material is far beyond the Eg range of the current commercial organic electrolyte, so it is easily oxidized during charging and discharging. With the increase of charging and discharging times, the capacity decreases and the service life also decreases.

The reason why the open-circuit voltage of the lithium-ion battery is selected to be 4.2V is that the Eg range of the electrolyte of the existing commercial lithium-ion battery is 1V ~ 4.5V. If the open-circuit voltage is set to 4.5V, the output power of the lithium-ion battery may be increased, but it also increases the risk of battery overcharge, and the harm of overcharge has been explained by a lot of data, so there is no additional explanation here.

How to Connect Batteries in Series and Parallel?

CONNECTING-BATTERIES-IN-SERIES---PARALLEL
Series - Parallel Connected Batteries

If you have ever worked with batteries you have probably come across the terms series, parallel, and series-parallel, but what exactly do these terms mean?

Series, Series-Parallel, and Parallel is the act of connecting two batteries together, but why would you want to connect two or more batteries together in the first place?

By connecting two or more batteries in either series, series-parallel, or parallel, you can increase the voltage or amp-hour capacity, or even both; allowing for higher voltage applications or power hungry applications.

Connecting Batteries In Series

Connecting a battery in series is when you connect two or more batteries together to increase the battery systems overall voltage, connecting batteries in series does not increase the capacity only the voltage.

For example if you connect four 12Volt 26Ah batteries you will have a battery voltage of 48Volts and battery capacity of 26Ah.

To configure batteries with a series connection each battery must have the same voltage and capacity rating, or you can potentially damage the batteries. For example you can connect two 6Volt 10Ah batteries together in series but you can not connect one 6V 10Ah battery with one 12V 10Ah battery.

To connect a group of batteries in series you connect the negative terminal of one battery to the positive terminal of another and so on until all batteries are connected, you would then connect a link/cable to the negative terminal of the first battery in your string of batteries to your application, then another cable to the positive terminal of the last battery in your string to your application.

When charging batteries in series, you need to use a charger that matches the battery system voltage. We recommend you charge each battery individually to avoid battery imbalance.

CONNECTING BATTERIES IN SERIES

Connecting Batteries In Parallel

Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity, with a parallel battery connection the capacity will increase, however the battery voltage will remain the same.

For example if you connect four 12V 100Ah batteries you would get a 12V 400Ah battery system.

When connecting batteries in parallel the negative terminal of one battery is connected to the negative terminal of the next and so on through the string of batteries, the same is done with positive terminals, ie positive terminal of one battery to the positive terminal of the next. For example if you needed a 12V 300Ah battery system you will need to connect three 12V 100Ah batteries together in parallel.

Parallel battery configuration helps increase the duration in which batteries can power equipment, but due to the increased amp-hour capacity they can take longer to charge than series connected batteries.

CONNECTING BATTERIES IN PARALLEL

Series – Parallel Connected Batteries

Last but not least! There is series-parallel connected batteries. Series-parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system.

For example you can connect six 6V 100Ah batteries together to give you a 24V 200Ah battery, this is achieved by configuring two strings of four In this connection you will have two or more sets of batteries which will be configured in both series and parallel to increase the system capacity.

If you need any help with configuring batteries in series, parallel or series parallel please get in contact with one of our battery experts. (Article cited: power-sonic.com)

Battery Construction

12-volts-battery

The word battery simply means a group of similar components. In military vocabulary, a “battery” refers to a cluster of guns. In electricity, a “battery” is a set of voltaic cells designed to provide greater voltage and/or current than is possible with one cell alone.

The symbol for a cell is very simple, consisting of one long line and one short line, parallel to each other, with connecting wires:

cell

The symbol for a battery is nothing more than a couple of cell symbols stacked in series:

battery

As was stated before, the voltage produced by any particular kind of cell is determined strictly by the chemistry of that cell type. The size of the cell is irrelevant to its voltage. To obtain greater voltage than the output of a single cell, multiple cells must be connected in series. The total voltage of a battery is the sum of all cell voltages. A typical automotive lead-acid battery has six cells, for a nominal voltage output of 6 x 2.0 or 12.0 volts:

12 volts battery

The cells in an automotive battery are contained within the same hard rubber housing, connected together with thick, lead bars instead of wires. The electrodes and electrolyte solutions for each cell are contained in separate, partitioned sections of the battery case. In large batteries, the electrodes commonly take the shape of thin metal grids or plates and are often referred to as plates instead of electrodes.

For the sake of convenience, battery symbols are usually limited to four lines, alternating long/short, although the real battery it represents may have many more cells than that. On occasion, however, you might come across a symbol for a battery with unusually high voltage, intentionally drawn with extra lines. The lines, of course, are representative of the individual cell plates:

unusually high voltage symbol for battery

How is the Size of the Battery Relevant?

If the physical size of a cell has no impact on its voltage, then what does it affect? The answer is resistance, which in turn affects the maximum amount of current that a cell can provide. Every voltaic cell contains some amount of internal resistance due to the electrodes and the electrolyte. The larger a cell is constructed, the greater the electrode contact area with the electrolyte, and thus the less internal resistance it will have.

Although we generally consider a cell or battery in a circuit to be a perfect source of voltage (absolutely constant), the current through it dictated solely by the external resistance of the circuit to which it is attached, this is not entirely true in real life. Since every cell or battery contains some internal resistance, that resistance must affect the current in any given circuit:

ideal real battery 1

The real battery shown above within the dotted lines has an internal resistance of 0.2 Ω, which affects its ability to supply current to the load resistance of 1 Ω. The ideal battery on the left has no internal resistance, and so our Ohm’s Law calculations for current (I=E/R) give us a perfect value of 10 amps for current with the 1-ohm load and 10 volt supply. The real battery, with its built-in resistance, further impeding the flow of current, can only supply 8.333 amps to the same resistance load.

The ideal battery, in a short circuit with 0 Ω resistance, would be able to supply an infinite amount of current. The real battery, on the other hand, can only supply 50 amps (10 volts / 0.2 Ω) to a short circuit of 0 Ω resistance, due to its internal resistance. The chemical reaction inside the cell may still be providing exactly 10 volts, but the voltage is dropped across that internal resistance as current flows through the battery, which reduces the amount of voltage available at the battery terminals to the load.

How to Connect Cells to Minimize the Battery’s Internal Resistance?

Since we live in an imperfect world, with imperfect batteries, we need to understand the implications of factors such as internal resistance. Typically, batteries are placed in applications where their internal resistance is negligible compared to that of the circuit load (where their short-circuit current far exceeds their usual load current), and so the performance is very close to that of an ideal voltage source.

If we need to construct a battery with lower resistance than what one cell can provide (for greater current capacity), we will have to connect the cells together in parallel:

batterys internal resistance

Essentially, what we have done here is to determine the Thevenin equivalent of the five cells in parallel (an equivalent network of one voltage source and one series resistance). The equivalent network has the same source voltage but a fraction of the resistance of any individual cell in the original network. The overall effect of connecting cells in parallel is to decrease the equivalent internal resistance, just as resistors in parallel diminish in total resistance. The equivalent internal resistance of this battery of 5 cells is 1/5 that of each individual cell. The overall voltage stays the same: 2.0 volts. If this battery of cells were powering a circuit, the current through each cell would be 1/5 of the total circuit current, due to the equal split of current through equal-resistance parallel branches.

REVIEW:

  • A battery is a cluster of cells connected together for greater voltage and/or current capacity.
  • Cells connected together in series (polarities aiding) results in greater total voltage.
  • Physical cell size impacts cell resistance, which in turn impacts the ability for the cell to supply current to a circuit. Generally, the larger the cell, the less its internal resistance.
  • Cells connected together in parallel results in less total resistance, and potentially greater total current.

Cracking the Code of a Scientific Anomaly: Decades-Old Mystery of Lithium-Ion Battery Storage Solved

Yu-Lab-Battery-Testing-System-scaled

For years, researchers have aimed to learn more about a group of metal oxides that show promise as key materials for the next generation of lithium-ion batteries because of their mysterious ability to store significantly more energy than should be possible. An international research team, co-led by The University of Texas at Austin, has cracked the code of this scientific anomaly, knocking down a barrier to building ultra-fast battery energy storage systems.

The team found that these metal oxides possess unique ways to store energy beyond classic electrochemical storage mechanisms. The research, published in Nature Materials, found several types of metal compounds with up to three times the energy storage capability compared with materials common in today’s commercially available lithium-ion batteries.

Yu Lab Battery Testing System

By decoding this mystery, the researchers are helping unlock batteries with greater energy capacity. That could mean smaller, more powerful batteries able to rapidly deliver charges for everything from smartphones to electric vehicles.

“For nearly two decades, the research community has been perplexed by these materials’ anomalously high capacities beyond their theoretical limits,” said Guihua Yu, an associate professor in the Walker Department of Mechanical Engineering at the Cockrell School of Engineering and one of the leaders of the project. “This work demonstrates the very first experimental evidence to show the extra charge is stored physically inside these materials via space charge storage mechanism.”

To demonstrate this phenomenon, the team found a way to monitor and measure how the elements change over time. Researchers from UT, the Massachusetts Institute of Technology, the University of Waterloo in Canada, Shandong University of China, Qingdao University in China and the Chinese Academy of Sciences participated in the project.

At the center of the discovery are transition-metal oxides, which are compounds that include oxygen bonded with transition metals such as iron, nickel and zinc. Energy can be stored inside the metal oxides — as opposed to typical methods that see lithium ions move in and out of these materials or convert their crystal structures for energy storage. And the researchers show that additional charge capacity can also be stored at the surface of iron nanoparticles formed during a series of conventional electrochemical processes.

Yu Advanced Electrode Material Lab

A broad range of transition metals can unlock this extra capacity, according to the research, and they share a common thread — the ability to collect a high density of electrons. These materials aren’t yet ready for prime time, Yu said, primarily because of a lack of knowledge about them. But the researchers said these new findings should go a long way in shedding light on the potential of these materials.

The key technique employed in this study, named in situ magnetometry, is a real-time magnetic monitoring method to investigate the evolution of a material’s internal electronic structure. It is able to quantify the charge capacity by measuring variations in magnetism. This technique can be used to study charge storage at a very small scale that is beyond the capabilities of many conventional characterization tools.

“The most significant results were obtained from a technique commonly used by physicists but very rarely in the battery community,” Yu said. “This is a perfect showcase of a beautiful marriage of physics and electrochemistry.”

UPS Backup Battery

UPS-Backup-Battery

Power failures do occur at times in our places of residents, businesses, and workplaces. This power failure can last for an extended period. And as we know, without electricity, all our work or pleasure will stop. Therefore, there is the need to have backup systems so that our work is protected from damage or data loss.

Also, backup systems help us minimize the financial loss caused by blackouts, low voltages, and other power supply problems.

Therefore, let us learn one excellent backup system known as an Uninterruptible power supply (UPS).

UPS-Backup-Battery

What is the UPS Backup Battery?

An Uninterruptible power supply (UPS) is also known as a battery backup, is an electronic device that provides emergency power when your regular power supply fails. UPS provides instant protection from input power interruptions by giving out the stored energy in batteries, robust capacitors, and flywheels.

Instant loss of power and power surges are two leading causes of damage to your devices. Thus, UPS protects hardware components of machines such as computers, data centers, telecommunication equipment, and all other electrical equipment. Power disruption can cause damage, fatalities, severe business disruption, or data loss.

UPS comes in different sizes, ranging from those meant to protect one computer without a monitor to those large units used to power entire data centers or buildings. Cheap power strips can protect your electrical devices but do not offer protection against drops in voltage, brownouts, blackouts, and other power supply problems.

Let us take, for instance; you are dealing with a project at home on your laptop with it plugged into an appropriate surge protection strip. You are busy with your work, and then suddenly, there is a power blackout. Although all the devices go off, your work won’t be interrupted since the laptop has a battery. This offers time to save your work then shut down your computer.

But for desktop computers, it is a different case. If you worked on your project on a desktop computer during the outage, then the system goes off when power is interrupted. This leads to loss of unsaved work and also gives your computer a lot of stress. UPS now plays its role here. It offers a window of time to save your work then shut the computer down in the right way.

You can also work for the entire period of interruption using the power stored in the UPS. Even in your absence, many UPS units come with software that enables them to detect a power outage and enables the computer to shut down automatically.

Main Types Of UPS Units

There are three main types of UPS units, namely:

A standby UPS unit – This type of battery backup charges its battery and then waits for the main power to be interrupted. When there is a power outage, the Standby UPS switches to the battery backup. It can support the device for a period of between 20-100 milliseconds, which is within the acceptable tolerance threshold.

A Line-Interactive UPS unit has the same design as a standby UPS unit, but a special transformer is included. This particular transformer makes this type of UPS better in dealing with brownouts and power surges. If you are residing in an area frequently affected by brownouts, this is the device to purchase.

An online UPS unit – this is the most expensive type of UPS. It completely separates the device attached to it from the wall power. There is never a single millisecond of power interruption with this backup system when there is power loss. The device is effectively an electronic firewall between your devices and the world, scrubbing and stabilizing all the electricity your devices are exposed to.

Can UPS Work Without the Battery?

UPS works mostly on batteries. Most UPS runs on batteries, and they cannot operate on dead or missing batteries. But in case you have the one that runs without batteries, then you will get the same voltage regulation and surge as you will be working with batteries.

Without batteries, the UPS will offer minimal protection, and even only the UPS’s surge side will work. You will not get line conditioning without a well-functioning battery. It is good to always have healthy batteries in your UPS for maximum protection of your hardware devices.

How do You Pick the Right UPS Backup Battery?

Picking the right battery for your home or device is always crucial. But these are the factors to consider when purchasing a UPS battery;

Durability

When choosing your UPS batteries, you should consider the batteries that can last for an extended period. Batteries that last for a short period are costly because you will require frequent replacements of your battery.

Size

Know the size of the battery that your UPS backup system requires. Do not purchase before checking because you can end up purchasing over-sized or under-sized batteries.

Appliances To Be Protected

It is always excellent to know the number and size of the appliances you want to protect using your UPS. If you are using the UPS in your computer, only then pick the small units UPS, but if used to support the entire building or home, you will need to have UPS with higher units.

Cost

Cost always plays a crucial role in the purchase of any product. It is good to purchase batteries that will not affect your budget. But the price should not be considered so much that the quality is left out. What benefit will you get if you purchase a battery at a lower price but dies after a few days? You will get a significant loss from cheaper batteries.

Type Of UPS

There are three main types of UPS discussed above. They have different power consumption rates. Therefore, it is good to know the type of UPS’s power consumption rate that you are currently using.

Conclusion

It is said that preventing an accident before it happens is wise. Therefore, it is crucial to protect your devices before becoming a victim of damages or data loss. Install a UPS in your workplace, home, or business, and get the best results. Always ensure that your UPS has healthy and working batteries. (Article cited: large.net)

The systems using AGM batteries require replacement once a year to ensure reliability. Generally, the labor cost of replacing AGM batteries exceeds the cost of the product itself, especially in Australia, Europe, North America and other places. The risks and hazards of frequent battery replacement cannot be ignored.
