12

Operation Conditions

Charge

0℃~50℃, 60±25%R.H.

Low temperature charging like below 0℃ gets lower capacity and reduces cycle life.

Discharge

-20℃~60℃, 60±25%R.H.

13

Storage Conditions

-20℃~55℃, 60±25%R.H.

Cell must be recharged per half year, while battery pack with BMS per three months.
