rechargable battery This series are intended for using in hight temperature environment. The main characteristics are as follows: 1.Excellent charging function in high temperature condition. Under the ambient temperature of 50℃, when discharging the battery at 0.2C current after charging at 0.05C current for 48h, the battery can fulfill 90% of the rated capacity. 2.Capable of lasting charging The positive and negative electrode as well as the separator has nice performance in high temperature situation, which ensures the battery can endure overcharge in high temperature environment. 3.Life cycle in high temperature environment. The battery is charged and discharged or dinarily in gradual rising temperature. 4. Stable performance The best raw material ally with advantage prescription to make sure the battery has stable performance 5.Environmental-friendly Free of Cd, Pb, Hg and other poison element,nopollution to environment. 6.Usage Widely used in solar power light/emergency lights and back-up electricity supply system.
