The use of lithium batteries depends on the life of the charge and discharge cycle. Usually, an ordinary 18650 can meet the standard of 600 times, and good quality can meet the requirement of 800 times. once a day, but generally can reach four years of use cycle.
If the lithium battery is not used once and stored for a long time, it requires regular maintenance. According to the requirements, half-loaded storage is required and it should be placed in a place. ventilated, cool and dry environment.
Note
Additional constant voltage charging once every three months, the charging voltage is 3.85V, and there is a charge and discharge cycle of 0 .2 C every six months. For storage, auto. -the discharge voltage is low. Batteries must be selected and disposed of in time. Batteries stored for a long timeperiod can last more than ten years, but after ten years, their capacity and internal resistance will also decrease to a large extent.
