The battery specification GB/T182872000 mentions that the lifespan of lithium battery cells is 300 cycles and the capacity is less than 80% of the original capacity. In fact, for current lithium battery cells, the lifespan is more than 300 cycles; For example, there are many domestic lithium batteries produced by powerful lithium battery manufacturers such as Grep Battery, BYD, Gaoneng and Lishen, which have shown that they can reach 500 cycles under normal use.
