Performance and Test Conditions
1. Standard Charge/Discharge
Standard Charge : 0.2C
Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 29.2V. The battery shall then be charged at constant voltage of 29.2 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.05CA. The battery shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
Standard Discharge : 0.2C
Battery shall be discharged at a constant current of 0.2C to 20.0V @ 20º ± 5C
If no otherwise specified, the rest time between charging and discharging is 30min.
2. Standard test conditons
Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.
