You can't - it has worn out from use.

Keeping batteries in the fridge can technically increase their life and help them keep charge fr longer but it won't fix worn out batteries.

Your battery needs to be replaced. Don't fiddle with it. If the old battery is mishandled or disposed of improperly, it could rupture and become a fire hazard.
