The rated operating temperature range of the battery is -20℃--55℃. All technical data are measured at a rated temperature of 25°C. The ideal operating temperature range of the battery is 20℃±5℃. Too high temperatures will shorten battery life, and too low temperatures will reduce usable capacity. The absolute upper limit of temperature is 55°C.
