Lithium ion battery manufacturers teach you how to test battery capacity.household energy storage lithium battery Product

release time:2023-04-14 Hits: Popular:AG11 battery

　　Lithium -ion battery manufacturers tell you how to detect the capacity of lithium -ion batteries. The capacity of lithium -ion batteries determines the life of the equipment. Generally, lithium -ion battery manufacturers are equipped with special equipment for testing. Because the minimum discharge voltage of lithium ion batteries is 2.75 V, the voltage below 3 V is meaningless for the test of lithium ion batteries.

　　The capacity of lithium ion batteries is based on "An Shi" and "Mianho. For example, a 500 mAh lithium -ion battery, if its working current is 10 mA, it can work for 50 hours in a row. Usually In the case, use 0.5 C to detect lithium ion batteries.

　　1. Full the battery, the voltage after the battery is charged is 4.2 V;

　　2. The use of a multimeter is a lithium ion battery with a constant current 0.5 C, discharge according to the capacity of the battery, and set the end voltage to 3 V;

　　3. The time to discharge with constant current is multiplied by discharge current, that is, the capacity of the battery; test: If the constant current discharge time is less than 2 hours, it means that the rated voltage is insufficient and there may be counterfeiting.

　　Lithium -ion battery manufacturers teach you how to detect the capacity of lithium -ion batteries. Taking the 1,000 MAH lithium ion battery as an example, we must first understand the following voltage:

　　1. Charging end voltage: That is, no load, that is, the highest voltage in non -run state, usually 4.2 V.

　　2. Work/rated voltage: It is also a load. Usually the voltage at the time of work is 3.7 V.

　　3. Discharge end voltage: That is, the voltage that cannot work normally. There are two types of 3 V and 2.75 V.
