Nowadays, the name Duracell is synonymous with batteries. That said, it’s no surprise the American company garnered a spot on our list given what the StayCharged are capable of. The batteries last 50 percent longer than standard alkaline batteries when used in high-draining devices such as game controllers and baby monitors, and if stored, they retain the bulk of their charge for up to a year. You can recharge the batteries up to 400 times before noticeable degradation occurs and Duracell even guarantees the batteries will last at least five years when predominantly used in high-draining devices. The latter point makes the StayCharged ideal for the avid gamer on a budget.
