3. Test conditions of temperature performance
The battery Cells shall be charged with constant current 0.2C to3.65V, then charging with constant voltage 3.65V to 0.01C under 20±5℃ and discharged at 0.2C to 2.0 V. Cells shall be stored for 4 hours at the test temperature prior to discharging and then shall be discharged at the test temperature, The percentage shall be calculated using discharging capacity compared to the minimum capacity.
