How long is lithium battery used?

release time:2023-03-07 Hits: Popular:AG11 battery

　　Lithium battery life is not calculated by years, but is calculated on the cycle. The life of lithium batteries is "500 times", which refers not to the number of charging, but a cycle of charging and discharge.

　　Nowadays, mobile phones are used in lithium batteries. Most of the lithium batteries are generally about 500 times, which means that from 0-100 for a loop (a cycle of 100 is one cycle). The internal resistance becomes large, the internal chemical element activity is reduced, and the rapid consumption stage is entered.

　　A charging cycle means that all the batteries of the battery are full to empty, and then the process of charging from empty to full, which is not the same as the charge. For example, a lithium battery uses only half of the electricity on the first day, and then fills it out. If the next day is still the same, it will be charged in half, and a total of two charging can only be regarded as one charging cycle, not two.

　　Therefore, it is usually possible to complete a cycle after several charging. Every time a charging cycle is completed, the battery capacity will be reduced. However, this power reduction is very small. After many cycles of high -quality batteries, 80%of the original capacity will still be retained. Many lithium battery power supply products are still used as usual after two or three years.
