Features & Description of Ultra-Low Self-Discharge Ni-MH Batteries

Application Areas of Ultra-Low Self-Discharge Ni-MH Batteries

BPI Low-Temperature Ni-MH Batteries deliver exceptional performance in extreme conditions, operating efficiently across -40℃ to 55℃. They achieve 46% efficiency at -40℃, 75% at -30℃, and 76% at 55℃, surpassing standard batteries. The multi-tab design reduces internal resistance by 7-8mΩ, enhances discharge platform by 15mV, and supports 7C high-rate discharge with 20% extended 1C cycle life (60-70 cycles). Rigorous safety tests (150℃ heat and short-circuit) and patented anti-explosion technology ensure reliability.
