Save time, money, and the earth by vowing never to use disposable batteries again. Get the best power, cycle life, and charge retention with Energizer® NiMH rechargeable batteries. Requires either the Fast Charger or Universal Charger (neither included). We highly recommend the Fast Charger since it only takes 15 min to recharge AA and AAA NiMH batteries--3 charges during 1 class period.

Four AA batteries and car adapter included with Fast Charger make it a great deal. Charging C, D, or 9-V NiMH batteries also requires the Universal Charger (also charges AA and AAA batteries).
