Ultra-Low Self-Discharge Batteries: Long-Lasting Power, Hassle-Free Storage, Efficient Energy Solution

BPI ultra-low self-discharge NiMH battery uses Sanyo's Japanese technology, with over 70% charge retention after 10 years at room temperature. It intelligently recovers capacity when voltage drops below 0.8V and operates in extreme environments from -40°C to 60°C. With over 2000 cycles and a self-discharge rate 1/5 of conventional batteries, it significantly extends standby time. Designed for high-reliability applications like TBOX, elevator backup power, and solar lights, its ultra-low self-discharge technology highlights our core advantage
