Items Test Conditions Requirements
Capacity Retention Fully charging, store them at (20 ± 5) for
Discharging time>250min
28 days, then discharge to 30.0V @0.2C.
Cycle Life @251 Discharge to 27.5V @0.2C, then Charge the battery @0.2C to
reach 42.0V. Then charge the battery at constant 42.0V voltage until the
charging current decreasing to 0.02C. Rest for 10 min. discharge to 30.0V@ 0.2C
and rest for 10 min. Continue the charge/discharge cydes until discharge
capacity lower than 80% of rated capacity. Cycles life M300
Storage Charge the battery to 40%~65% of its rated capacity using standard
charging mode, then keep it in an 20t ± 5*C, humidity 45% ~ 85% room for 12
months, fully charge and discharge it @0.2C until voltage down to 30.0V.
Discharge time>210min
(The testing sample should be within 3 months dated from production date)
