Ever wondered why your devices lose power so quickly?
Mystery Hour Question
Do rechargeable batteries lose power even when they aren't in use?
Qualifications: Inquisitive Mind
Answer: Depends on what kind of rechargeable battery it is, if it is a battery that is alkaline then they hold they charge for a lot longer. If it’s a nickel metal hydrate battery it will self-discharge anyway. If you continuously recharge a rechargeable battery you will kill cells.
