4. Test conditions
4.1 Standard Test Conditions
All tests are conducted at temperature 25±2℃, humidity was 15%~90%RH, atmospheric pressure at 80~106kPa.Unless there are other special instructions, all performance was tested with unused cells within 1 month after production date.
4.2 Standard Charge Method
The "Standard Charge" means in an ambient temperature of 25±2℃, the cell was discharged with 1C constant current to cut-off voltage 2.0V, standing 1hour. Then charged it with 1C constant current to 3.65V, then change into constant charge mode, until the charging current down to 0.05C, then stop charging and standing 1h.
