FAQ

Generally, what are Lithium-Ion Batteries?
Lithium-ion batteries are advanced rechargeable batteries where lithium ions move between the anode and cathode during charge and discharge. Renowned for their high energy density battery and absence of memory effect, they are lighter than lead-acid batteries and offer a higher open circuit voltage for efficient power transfer at lower currents.

Features of Ionic Lithium-ion Deep Cycle Batteries (Himax Electronics utilizes similar advanced LiFePO4 technology):

While the text refers to “Ionic,” Himax’s premium Li-ion batteries embody these cutting-edge features for superior performance:

Lightweight: Up to 80% lighter than comparable lead-acid alternatives, offering a true drop-in replacement for your OEM battery.
Extended Lifespan: Lasts 300-400% longer than lead-acid, with an expected 8-10 years of battery life.
Enhanced Safety: No explosive gasses during charging, no acid spills, and environmentally friendly (no lead or heavy metals). Our advanced Battery Management System (BMS) protection ensures safe and reliable operation, guarding against overcharging, short circuits, and overheating.
High Discharge Current: Our batteries maintain a higher voltage during discharge, offering more usable energy even when capacity is low.

What are LiFePO4 (Lithium Iron Phosphate) Batteries?
Lithium Iron Phosphate (LiFePO4) batteries offer significant advantages over traditional LiCoO2 chemistries. They provide much higher specific capacity, superior thermal and chemical stability, enhanced safety, improved cost performance, enhanced charge and discharge rates, and a significantly enhanced cycle life of over 2,000 charge cycles.

Why Choose Himax Electronics’s High-Performance Li-ion Deep Cycle Energy Storage Batteries?

Himax Electronics batteries are engineered for excellence, providing numerous advantages over standard lead-acid batteries for energy storage:

Substantially Lighter: Experience the benefit of a fraction of the weight, making installation and handling easier.
More Powerful: Operate at a higher voltage, ensuring consistent, robust power even as capacity decreases.
Low Self-Discharge Rate: Go for months without worry; our chemistry loses less than 3% charge per month.
Environmental Friendly: Our batteries contain no toxic substances, offering a safe, maintenance-free, and environmentally friendly solution.
Long Lasting: With an expected 8-10 years of use, Himax batteries easily outlast any lead-acid alternative.
Fast Recharging: Benefit from up to 5 times faster charging and superior charge efficiency, saving time and energy.

Himax Electronics Advantages Over Other Li-ion Battery Suppliers:

Internal Cell Balancing Circuit: Our batteries feature a micro-processor controlled internal cell balancing board to maximize the performance and lifespan of each cell.
Advanced Battery Management System (BMS): Each Himax custom battery pack includes a robust BMS, offering comprehensive protection against overcharging, over-discharging, short circuits, and overheating, ensuring optimal lifespan and safety.
Quality Engineering: Our innovation laboratory prides itself on utilizing the highest quality components in all phases of design and construction, guaranteeing the safety and quality of every Himax product.
Prismatic Cells (for custom solutions): Unlike cylindrical cells, our prismatic cell designs offer flexible sizing for a perfect drop-in fit in most vehicles, along with superior thermal management.

Himax Electronics “Deep Cycle” Capacity (Ah) Rating vs. Lead-Acid Ah Ratings:

Himax “Deep Cycle” batteries boast true lithium capacity ratings at 1C discharge rate. A 12Ah Himax Electronics Li-ion battery will deliver 12A for 1 hour. In contrast, a 12Ah lead-acid battery, often rated at 20hr or 25hr, might only provide 6Ah of usable energy in 1 hour before damaging deep discharge occurs. Himax batteries can be safely discharged to 90% DOD, offering significantly more usable capacity than lead-acid counterparts which suffer from rising internal resistance and limited discharge depths (often only 20% of mfg. rating usable). Our batteries maintain a consistently higher voltage during discharge, ensuring superior performance.

IMPORTANT: PRE-USE GUIDELINES

DO:

Perform a Pre-Installation Check! Ensure a thorough examination before installation:
Inspect Each Cell: Visually check for any damage, swelling, leaks, or missing accessories. Do not use a cell if the casing is pierced, leaking, cracked, or otherwise visibly damaged.
Clean the Terminals: Ensure bus bars, wire terminal lugs, and terminals are clean and free from corrosion or debris. This helps reduce resistance between the DC terminal and cable connection.
Test Voltage and Capacity: Use a multimeter to check each cell’s voltage and internal resistance, and a battery analyzer or specialized tester to confirm capacity.
Top Balance Before Use: Charge all cells to full voltage before assembling them. We recommend using chargers specifically designed for Li-ion cells.

DON’T:

Do Not Discharge Immediately After Delivery: Allow the battery to settle before use.
Do Not Mix Cells from Different Series: Even if they are the same type and capacity, avoid mixing cells from different manufacturing series or batches. Always use cells from the same batch.
Avoid Loose Terminal Connections: Ensure all terminals are securely fastened to prevent performance issues.
