Don't buy

We don't recommend any carbon zinc batteries because alkaline and lithium perform considerably better and have longer shelf lives. The Panasonic Extra Heavy Duty performs terribly across the board in comparison. In addition, many of the alkaline batteries we tested were cheaper to buy than the Panasonic Extra Heavy Duty.
