The lithium polymer battery cycle life testing standards

Lithium polymer battery Li-ion battery under the conditions of 20 ± 5 ℃ according to 0.5C charge changed to constant voltage charging, when the polymer lithium battery voltage reaches 4.2V, until the charge current is less than or equal to # / # 186 # / # capacity 0.01C, stop charging stand for 0.5h to 0.5C discharge to 3.0V way to cycle life

when three consecutive discharge capacity <initial capacity of 80% for the termination, the cycle life of ≥ 300.
