Maximum discharge current
108 A (5 c)
Internal resistance
18 mOhm
Operating temperature range
Discharge: -40 ~ 60 °C, Charge: -20 ~ 60 °C, Storage: -40 ~ 60 °C
Addiction Cном. from °C
40 °C - 103 %, 25 °C - 100 %, 0 °C - 86 %
Charge voltage
Буферный режим – 13.5 - 13.8 V, Temperature coefficient -20 мВ/ ˚С, Cyclic mode – 14.4 - 15.0 V, Temperature coefficient -30 мВ/ ˚С
Maximum charge current
2.16 А
Self-discharge
Могут храниться to 6 months at 25 ˚С, after which a charge is required. Higher temperatures reduce shelf life
Life time
8 years in buffer mode или более 260 cycles заряда-разряда в циклическом режиме at 100% discharge
*The battery must be charged before use. At higher ambient temperatures, storage time is reduced
