Discharge termination voltage: The rated voltage of lithium-ion batteries is 3.6V (some products are 3.7V), and the terminal discharge voltage is 2.5-2.75V (the battery plant gives a working voltage range or the termination voltage is given. Each parameter is slightly different. To. The discharge termination voltage of the battery should not be less than 2.5 (n is the number of batteries connected in series). Continuously discharge than the termination discharge voltage is called overlap. After the release, the battery life will be shortened, which will cause the battery to fail. When the battery is not used, the battery should be charged to the capacity of 20%, and then the moisture -proof packaging should be saved. The voltage is detected once 3 to 6 months, and charging is performed to ensure that the battery voltage is within the range of the safe voltage (above 3V).

　　Dry current: Lithium -ion batteries are not suitable for large current discharge. When large current discharge, it will generate higher temperature and loss energy and reduce discharge time. Therefore, the battery production plant gives the maximum discharge current, and the maximum discharge current given in the product characteristic table cannot be used in use.

　　Discharge temperature: The discharge curves at different temperatures are different. At different temperatures, the discharge voltage and discharge time of lithium-ion batteries are also different. The battery should be discharged (work) within the temperature range of -20 ° C to+60 ° C.
