. They discharge faster and cannot recharge to the same level that they were able to when new.
How do you store rechargeable batteries when not in use?
What is the lifespan of a rechargeable battery?
Assuming the average lifespan of a rechargeable battery is

Rechargeable batteries can be recharged and reused from
500 to 1000 times
depending on usage. The different battery technologies affect the performance of the batteries.
Do lithium batteries go bad if not charged?
Lithium Ion batteries “go bad” when they are stored in discharged state
. It is all about battery voltage. If voltage is too low – undesireable chemical reactions will happen and battery will degrade. If battery is not empty and not used for long time – it will be fine.
