Can lithium AA batteries be recharged?
Lithium batteries are primary cell batteries, which means they cannot be recharged once empty . They use the metal lithium as an anode. Lithium batteries have a high charge density, meaning they last longer than other batteries and can hold more power.
Do batteries expire?
Unfortunately, yes. All batteries have an expiration date mentioned on the packaging and on the cell itself . The battery may still work after that date, but with minor performance.
Why does freezing a battery revive it?
