3.Test Conditions

3.1Standard Test Conditions

3.1.1 All tests defined in this Product Specification are conducted at temperature 25℃±5℃; humidity 15℅~90% RH; atmospheric pressure 86kPa~106kPa.

3.1.2. Unless there are other special instructions, all performance was tested with unused cells within 1month after production date.

3.2Standard Charge Method

The "Standard Charge" means in an ambient temperature of 25℃±5℃, the cell was discharged with 1C constant discharge current to cut‐off voltage 2.0 V, stayed in 1hour. Then charged it

with 1C constant current to 3.65V, then change into constant charge mode, until the charging current is down to 0.05C, then stop charging and standing 1hour.
