Editor's Pick: Power-hungry devices like doorbells and game controllers drain regular batteries fast. Swap in these constant-voltage lithium batteries and you get a steady 1.5V from full charge to nearly empty, so performance won't feel weaker the longer you play. With a 3400mWh capacity and over 1,600 recharge cycles, they'll last a long time with repeated recharging. Just note you need a charger made specifically for 1.5V lithium batteries—don't use a NiMH charger.
