(25°C)
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.
