Everything You Need to Know About Lithium Battery Charging …
In essence, no matter how a Lithium battery is charged, a total of 300Q to 500Q of power is always added. Consequently, we may conclude that the life of a Lithium battery is proportional to the battery''s overall charge, not to the number of charges. Deep charge and shallow charging have similar impacts on lithium battery life.
