2. Safety test
Over charge and discharge: 0.1C charge for 48hrs No conspicuous deformation and/or leakage.0.2C discharge to 1.2V,Cornbine the battery with a 2.3Ω electric resistance, after stored for a period of 24 hrs, then test the Capacity with Standard discharge Conditions.
Vibration Test: Charge at current 0.1C for 16hrs; place for 24 hrs, check the battery before and after vibration. Vibration condition: Swing: 1.5mm, Frequency: 3000CPM, Vibrate for 1hr to any direction.
Drop Test: Charge at current 0.1C for 16hrs, place for 24 hrs, check the battery before and after fall down test; Iact condition: Fall down from height 1.2m to any direction on the hard-wood board( Thickness:10mm), test for 3 times.
Charge reserve: Standard charge Storage: 28 days Standard discharge (0.2C) ≥180min
Humidity: Standard charged, stand for 10 days at 33±3℃ and 80±5% of relative humidity No leakage
External Short Circuit: After standard charge, short-circuit the cell at 20 ℃ ± 5 ℃ until the cell teerature returns to ambient teerature.(cross section of the wire or connector should bemore than 0.75mm2) No fire and no
explosion
IEC Cycle Life Test: ≥500 cycle IEC61951-2(2003)7.4.1.1
