Deep cycle lithium ion battery 12V 50Ah reliability test
| No. | Items | Standards | Testing Methods |
| 1 | Vibration Testing | The appearance of battery should not leakage, break or explosion | Fix 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. |
| 2 | High Temperature Discharge Testing | The battery should be no remarkable breakage, distortion. Discharge
time should not less than 255mins | Place 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. |
| 3 | Low Temperature Discharge Testing | The battery should be no remarkable breakage, distortion. Discharge
time should not less than 180 minute | Place 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. |
| 4 | Constant Humidity & Temperature Testing | The battery should be no remarkable breakage, distortion. Discharge
time should not less than180mins | Place 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. |
| 5 | High & Low Temperature Storage | The battery should be no remarkable breakage, distortion. And
charge/discharge normally | Place 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 |
