When the battery needs to be stored for a long time, it should be charger to closet to 50% SOC with a voltage about 49.5V and placed under the recommended storage conditions. The battery needs to be charged at least every 6months if out of use.(Charge first , discharge then recharge 50%)) |
3.Test Conditions
3.1 Standard Test Conditions
3.1.1 Unless otherwise specified, all product performance specifications are tested at temperature 25℃±2℃,relative humidity 45%~75%RH.
3.1.3 Unless otherwise specified all product performance specifications are tested on unused products within 1 month of the date of manufacture.
3.2 Standard Charger Model
Standard charging refers to charging at the ambient temperature of 25±2℃ with 0.33c constant current to the charging limit voltage, and then charging at constant voltage to the charging current less than 0.02c.
3.3 Quick Charging Model
Fast charging refers to charging at 0.33c constant current to charging limit voltage, and then charging at constant voltage to charging current less than 0.02c.
3.4 Standard Discharge Model
Standard discharge is the discharge of the battery to the termination voltage at an ambient temperature of 25±2℃ with a current of 0.33c.
3.5 Quick Discharge Model
Rapid discharge is the discharge of 1C current to the termination voltage.
