Its maintenance-free design and high discharge rate make it ideal for backup power and off-grid applications. The battery meets UL and CE certifications for safety.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the EXP12180 Battery Ensure Safety and Durability?
The EXP12180 uses an Absorbent Glass Mat (AGM) design to prevent electrolyte leakage and resist vibrations. Its sealed construction eliminates maintenance requirements while providing overcharge protection. The lead-calcium alloy grids enhance corrosion resistance, ensuring a 5-7 year lifespan under proper cycling conditions.
The battery’s multi-layer separator technology combines glass microfiber and polyethylene membranes to prevent internal short circuits. This design withstands 15G shock resistance and maintains structural integrity during rapid charge/discharge cycles. Pressure-regulated valves automatically release excess gas during overcharging while maintaining a sealed environment. For extreme temperatures, the EXP12180 utilizes tin-coated copper terminals that resist sulfation even in high-humidity environments.

What Maintenance Practices Extend the EXP12180’s Lifespan?
Store at 50% charge in 15-25°C environments when idle. Clean terminals quarterly with baking soda solution to prevent voltage drop. Use torque-limiting tools to secure connections at 8-10 Nm. Equalize charge every 10 cycles using 15.5V for 2-4 hours to balance cell voltages.
Implementing a controlled discharge profile significantly impacts longevity. Avoid draining below 10.5V (1.75V/cell) as this accelerates plate sulfation. For seasonal storage, perform capacity checks every 3 months using a 10A load tester. When cleaning terminals, apply anti-corrosion gel containing zinc stearate after neutralization. Users should monitor charge acceptance weekly – a 15% reduction in charging current indicates potential aging.
“The EXP12180’s combination of high-purity lead plates and compressed AGM separators results in exceptionally low internal resistance (≤18mΩ). This enables 95% energy efficiency during discharge cycles – a 15% improvement over standard VRLA batteries. For cyclic applications requiring 150+ discharges annually, it’s become an industry benchmark.”

FAQs
- Can the EXP12180 Be Used in Series/Parallel Configurations?
- Yes, up to 4 units can be connected in series (48V) or parallel (72Ah). Ensure all batteries are within 0.1V open-circuit voltage difference before connecting.
- What Warranty Does ExpertPower Provide?
- 3-year pro-rated warranty covering manufacturing defects. Capacity below 60% within 12 months qualifies for free replacement.
- How to Test EXP12180 Health?
- Measure specific gravity (1.280±0.005) with a temperature-compensated hydrometer. Conduct load testing at C/20 rate – voltage should stay above 10.5V after 20 hours.
