Technical Requirements

1 Testing Conditions

1.1 Standard charge methods

1.1.1 Constant current/constant voltage charge method

At (25±5)℃, the cell should be charged to an upper voltage limit within (3.1～3.3)V with constant current I_Charge, then the cell be charged at that constant voltage until the charge current falls to below 0.5I_Charge. The said upper voltage limit is recommended to be 3.25V and no more than 3.3V.

1.1.2 Constant voltage charge method with protective resistor

At (25±5)℃, the charge circuit refers to the one in figure 1 and relevant parameters are demonstrated in Table 3. Charging continues until the charging current falls to less than 0.05mA.

1.2 Standard discharge procedures

1.2.1 Standard discharge at constant current

At (25±5)℃, the fresh cell should be discharged at constant current I_const selected between 0.03 to 0.1mA for the duration of (%DOD x Nominal capacity/I_const) hours , the cutoff voltage is 2.0V.

1.2.2 Standard discharge with constant resistance load

At (25±5)℃, the fresh cell be discharged continuously to the cutoff voltage of 2.0V with a loading equivalent resistor of 30kΩ in series.

1.3 Standard testing environment

Temperature: 20～30℃

Relative humidity: 25%～85%RH

Atmosphere pressure: 86～106kPa

Measuring and testing instruments as reference: program controlled Neware BTS standard coin battery
