1. CHARACTERISTICS
Unless special stated, tests should be carried out within one month of delivery.
Ambient conditions:
Ambient Temperature: 20±5℃
Relative Humidity: 65±20%RH
Notes: 1)Standard charge/discharge condition
Charge: 140mA(0.1C)×16hours
Discharge: 280mA(0.2C) to 1.0V
2）Except special explaining, the battery shall not leakage and PVC shall not breakage during the test.
