Cell Usage Instructions

Charging

The charging temperature range of the cell is -20℃~60℃.

Charge the cell to 4.25V with a constant current and constant voltage of 0.5C, with a cut-off current of 0.05C. It is not recommended to use a current exceeding 1C.

When charging at -20℃~-10℃, the current should not exceed 0.1C.

Do not charge continuously beyond the standard time.

Connect the positive and negative terminals of the battery correctly; reverse charging is strictly prohibited. If the positive and negative terminals are reversed, the cell cannot be charged. At the same time, reverse charging will reduce the charge-discharge performance and safety of the cell, and cause heating and leakage.

Discharging

The discharge temperature range of the cell is -40℃~60℃.

The discharge cut-off voltage is 2.5V, and the discharge cut-off voltage is 2.0V in an environment where the temperature is lower than 0℃. The maximum constant current discharge current is 3C.

It should be noted that during long-term non-use, the cell may be in an over-discharged state due to its self-discharge characteristics. To prevent over-discharge, the cell should be charged regularly to maintain its power at around 40% SOC.

Cell Connection

It is recommended to use ultrasonic welding or spot welding technology to connect the cell to the protection circuit module or other components.

Storage Recommendations

The cell should be stored in an environment with a temperature range of 0~45℃, relative humidity <65% RH, and free of corrosive gases.

The cell is best stored at 30%~40% SOC.

For long-term storage (more than 3 months), the cell should be stored in an environment with a temperature range of 0~25℃, relative humidity <65% RH, and free of corrosive gases.
