Deep cycle lithium ion battery 12V 50Ah reliability test

No.ItemsStandardsTesting Methods
1Vibration TestingThe appearance of battery should not leakage, break or explosionFix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.
2High Temperature Discharge TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than 255minsPlace a full charged battery under the environments of 55 for 2 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20±5 for 2 hours.
3Low Temperature Discharge TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minutePlace a full charged battery under the environments of -20 for 15-24 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20±5 for 2 hours.
4Constant Humidity & Temperature TestingThe battery should be no remarkable breakage, distortion. Discharge time should not less than180minsPlace a full charged battery under the environments of 40 and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 200mA to the cut-off voltage.
5High & Low Temperature StorageThe battery should be no remarkable breakage, distortion. And charge/discharge normallyPlace a full charged battery in a oven with 55±2 for2 hours, then keep it under 20±5 for 4hrs, then place it in a oven with -20±2 for 2 hours, then keep for 4 hours under 20±5, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times
