Parameters MODEL Product Specification Content Testing method Remark Charge Voltage 42V   Discharge Cut-Off Voltage 27V   Standard Charge Charge the battery at constant current of 0.2C to reach 42.0V.   Then charge the battery at constant 42.0V voltage until the charging current decreasing to 0.02C. Standard Discharge After the standard charging, rest for 1 hour then discharge to 25.0V@0.2C.   Rated Capacity Typical capacity: 12.72Ah Standard discharge after standard charge Operation Charging: 10~45°C 60±25%R.H Temperature Range Discharging: -20~45℃ Storage ≤ month: - 20~45*C 60±25%R.H Best 10~25°C for long-time storage Temperature ≤ months: -10 ~ 25C   ≤1year: 0 ~ 30°C Impedance ≤160mΩ   Product Electric Performance Test 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) Mechanical Performance Content Testing method Requirements Vibration Test After standard charging, put battery on the vibration table. 30 min experiment from X, Y, Z axis.
