❓ why
Why do batteries wear out even when they are not being used?
Quick Answer
Batteries slowly lose charge because of internal side reactions and self-discharge. The chemicals inside are not perfectly stable, even in storage.
The Full Story
Inside a battery, reactions can continue at a slow rate even when the device is switched off. This self-discharge happens because electrodes, electrolytes, and impurities can still undergo unwanted chemical changes. Temperature matters too: warmer conditions usually speed up these side reactions. That is why batteries left on a shelf for months or years often hold less charge than when they were new.
Key Facts
1.All batteries self-discharge to some degree
2.Higher temperatures usually increase self-discharge
3.Lithium-ion batteries still lose charge during storage
