Generally, What are Lithium-Ion Batteries?
Lithium-ion batteries are rechargeable power sources where lithium ions move between the anode and cathode during charge and discharge cycles. Highly valued in consumer electronics, these batteries boast high energy density, no memory effect, and a slow loss of charge when idle. Available in diverse shapes and sizes, lithium-ion batteries are significantly lighter than traditional lead-acid batteries and provide a higher open circuit voltage, enabling efficient power transfer at lower currents. They offer:
- Lightweight Design: Up to 80% lighter than comparable lead-acid batteries.
- Superior Longevity: Lasts 300-400% longer than lead-acid.
- Low Shelf Discharge Rate: Less than 2% per month compared to 5-8% for lead-acid.
- Drop-in Replacement: Seamlessly replaces your OEM battery.
- Expected 8-10 Years of Battery Life.
- Enhanced Safety: No explosive gasses or acid spills.
- Environmentally Friendly: Free from lead or heavy metals.
- Safe to Operate!
While “Lithium-ion” is a general term encompassing chemistries like LiCoO2, LiPo, and LiFePO4, Himax primarily focuses on designing, manufacturing, and marketing LiFePO4 batteries for our deep cycle and starter battery ranges.
What are LiFePO4 (Lithium Iron Phosphate) Batteries?
Lithium Iron Phosphate (LiFePO4) batteries offer distinct advantages over traditional LiCoO2-based lithium-ion batteries. They provide significantly higher specific capacity, superior thermal and chemical stability, enhanced safety, improved cost performance, faster charge and discharge rates, and an impressive cycle life of over 2,000 charge cycles, all within a compact, lightweight lithium battery package. Himax leverages this advanced chemistry to create highly reliable 12V 40Ah LiFePO4 Batteries.
Why Choose Himax Electronics’s Lithium-Ion “Deep Cycle” Energy Storage Batteries?
Himax’s 12V 40Ah Deep Cycle Battery solutions provide multiple advantages over standard lead-acid batteries for demanding energy storage applications:
- Substantially Lighter: Our 12V 40Ah RV Battery or 12V 40Ah Medical Lithium Battery is a mere fraction of the weight of a lead-acid equivalent.
- More Powerful & Consistent: Himax lithium-ion batteries maintain a higher operating voltage, delivering faster performance for longer durations. Unlike lead-acid batteries that drop to 12.5V at 20% capacity used, our lithium batteries sustain over 12.8V even with only 20% capacity remaining.
- Ultra-Low Self-Discharge Rate: While lead-acid batteries can lose 4%-25% of charge monthly, our lithium chemistry loses less than 3% per month. This means your 12V 40Ah Energy Storage Battery can remain unused for months without significant power loss.
- Environmentally Responsible: Himax batteries contain no toxic substances like poisonous lead or corrosive sulfuric acid, eliminating the risk of explosive gassing events common with lead-acid. They require no acid level maintenance or venting, making them a truly environmentally friendly battery.
- Exceptional Longevity: While cheap lead-acid batteries last 1-2 years and AGM/Gel types 3-5 years, Himax’s long cycle life battery solutions provide an impressive 8-10 years of use, far exceeding any lead-acid option. Proper usage, ensuring discharge not beyond 80% DOD, maximizes this lifespan.
- Rapid Recharging: Himax lithium-ion batteries can accept charge current up to 5 times faster than lead-acid, with a charging efficiency of about 97% (vs. 75% for lead-acid). This translates to less energy consumption and reduced strain on your charging system, whether it’s for solar energy storage or backup power supply.
What Advantages Does Himax Electronics’s “Deep Cycle Batteries” Have Over Other Batteries?
Himax incorporates the latest advancements in lithium-ion battery technology with custom features to deliver superior solutions:
- Internal Cell Balancing Circuit: Each Himax Electronics battery integrates a micro-processor controlled internal cell balancing board, meticulously designed to maximize the performance and longevity of every cell within the pack.
- Advanced Battery Management System (BMS): Our lithium-ion smart batteries feature a robust solid-state switch that controls temperature volatility and prevents overcharging/discharging, significantly improving the overall lifespan, performance, and safety of the battery pack.
- Quality Engineering & Components: Himax’s innovation laboratory prides itself on the design and construction of our batteries, utilizing the highest quality components at every stage. Our built-in intelligent components guarantee the safety and quality of each Himax product, from a single 12V 40Ah battery to a large custom battery pack.
- Prismatic Cells for Optimal Fit: Unlike cylindrical cells with limited sizing, Himax utilizes prismatic cells, which are rectangular packages. This allows for flexible design and sizing to perfectly match the dimensions of your battery case, ensuring a perfect drop-in fit for most vehicles and equipment, alongside superior thermal management properties.
How Does Himax Electronics’s “Deep Cycle” Capacity (Ah) Rating Compare to Lead-Acid Ah Ratings?
Himax Electronics 12V 40Ah Deep Cycle Batteries boast a true lithium capacity rating at a 1C discharge rate. This means a 40Ah Himax lithium-ion battery can reliably provide 40A for 1 hour. In stark contrast, most lead-acid batteries list a 20hr or 25hr Ah capacity rating; a “40Ah” lead-acid battery discharging at 1 hour would typically yield only 20Ah of usable energy. Furthermore, discharging lead-acid batteries below 50% Depth of Discharge (DOD) will cause damage.
Himax lithium-ion batteries feature 1/3 the internal resistance of a similar capacity lead-acid battery and can be safely discharged to 90% DOD. Lead-acid internal resistance increases as they discharge, meaning the actual usable capacity can be as low as 20% of their stated rating. Himax lithium-ion batteries maintain a consistently higher voltage throughout their discharge cycle, ensuring more usable power for applications like off-grid energy storage.
