2. Safety test
Over discharge: 0.1C charge for 48hrs No conspicuous deformation and/or leakage.
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
Vibration Resistance: Charge of voltage should be under 0.08V/pack, change of iedance should be under20milli-ohm/cell.
Drop Test: △V<0.02V/cell △Ri<5%/cell Charge at 0.1C for 16hrs,and then leave for 24hrs,check battery before / after drop
