Are alkaline batteries rechargeable?

Alkaline batteries are disposable, meaning they cannot be recharged after use. This is because the chemical reaction within alkaline batteries is irreversible during discharge; once the reaction is complete, the battery can no longer generate electricity.

Unlike alkaline batteries, rechargeable batteries (such as nickel-metal hydride and lithium-ion batteries) can be charged and discharged repeatedly. The chemical reaction within these batteries is reversible, so they can be recharged with an external power source to restore their power.

It is important to note that you should never attempt to recharge alkaline batteries. Doing so can cause safety hazards such as leakage of internal chemicals, swelling, or even explosion. For safety reasons, please dispose of alkaline batteries according to local recycling regulations after use.
