3 |
Low Temperature Discharging |
After standard charge, put the battery in a cooling box of -10±2℃ for 16~24hr ,and then discharge the battery with constant current of 0.2C5A and keep record of the discharging time. After 2hr of standby at 20±5℃, check the performance of the battery pack. |
Discharge time is no less than 3.5 hours. no explosion. |
4 |
High Temperature Discharging |
After standard charge, put the battery in a heating box of 55±2℃ for 2hr, and then discharge the battery with constant current 1C5A and keep record of the discharging time. After 2hr of standby at 20±5℃, check the performance of the battery pack. |
Discharge time is not less than 51 minutes. no explosion. |
5 |
Shelf Life |
After standard charge, shelve the battery pack for 28 days at 20±5℃,and then discharge it with constant current of 0.2C5A ,recording the discharging time. |
Discharge time is not less than 4.25 hours. |
6 |
Cycle Life |
Fully discharge the battery before this test ,then charge it with constant current 1C5A,when the voltage of the battery reaches the charge limited voltage , charge the battery with constant voltage until the charging current below 20mA,then have a 0.5h~1h rest period, next ,discharge with current 1C5A to the cut-off voltage .After a 0.5h~1h rest period ,begin next charge and discharge cycle. when two times over discharge time is less than 36min, life of the battery is end. |
Cycle life is not less than 1000 cycles. No liquid leakage during the test. |
NO |

Test Procedure |
Requirements |
1 |
Constant Humidity and Temperature |
1. After standard charge, keep the battery for 48 hr in an insulated box at constant relative humidity of 90~95% and constant temperature of 40±2℃; 2. Take out the battery pack from the box and standby for 2hr at room temperature and check the battery; 3. Finally discharge the battery with constant current 0f 1C5A to the cut-off voltage and keep record of the discharging time. |
