What characterizes non-rechargeable batteries?

Non-rechargeable batteries are characterized by their use of irreversible reactions. When a non-rechargeable battery is used, the chemical reactions that occur within it lead to the production of electricity, but these reactions cannot be reversed once the battery is depleted. As a result, the materials undergo permanent changes, and the battery cannot be restored to its original charged state.

In contrast, rechargeable batteries rely on reversible chemical reactions, which allow them to be recharged and used multiple times. The notion of a battery being used indefinitely is not applicable in this context, since all batteries, whether rechargeable or not, will eventually run out. Additionally, the option stating no chemical reactions is incorrect because all batteries, including non-rechargeable ones, function through chemical reactions to generate electricity. The irreversible nature of the reactions in non-rechargeable batteries is what defines their operation and lifecycle.
