|
Cycle Life
@25℃ |
Discharge to 40V @0.2C, then Charge the battery @0.2C to reach 58V. Then charge the battery at constant58.4V voltage until the
charging current decreasing to 0.02C. Rest for 10 min. discharge to 40V@ 0.2C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity. Cycles life ≥3000 |

|
storage
|
Charge the battery to 40%~65% of its rated capacity using standard charging mode, then keep it in an 20℃±5℃, humidity 45%～85% room
for 12 months, fully charge and discharge it @0.2C until voltage down .(The testing sample should be within 3 months dated from production date) Discharge time≥360min |
