Why are alkaline cells preferred for long-term storage?

Alkaline cells are preferred for long-term storage primarily because they have a slower discharge rate and a longer shelf life compared to other types of batteries. This means that when alkaline batteries are stored without use, they maintain their charge more effectively over extended periods. The chemical composition of alkaline cells allows them to retain energy longer than other batteries, such as carbon-zinc cells, which tend to lose their charge relatively quickly even when not in use.

The slower discharge rate ensures that devices can be stored for longer periods without worrying about the batteries draining or needing replacement, making alkaline batteries an ideal choice for backup or infrequently used devices. This extended shelf life is particularly advantageous for emergency supplies, remote controls, and other applications where access to power sources may be limited.
