When should I use Energizer^® MAX™ batteries?
Energizer ^® MAX™ batteries provide long lasting power in a full range of devices-everything from devices that keep you safe, like flashlights and smoke detectors, to ones that add fun to your life, like toys, radios and CD players, to devices that help you work, like calculators and hand-held organizers.

I like to stock up on batteries. How long do they last in the package?
Energizer ^® MAX™ batteries last seven years in the package, a shelf life as long as any alkaline battery.

How should I dispose of my batteries?
You can dispose of Energizer^® batteries with regular household trash—Energizer^® was the first to remove all added mercury from alkaline batteries.

Who invented alkaline batteries?
Lew Urry, an Energizer^® scientist, invented the first commercially viable alkaline battery more than 40 years ago. Today his handmade, prototype cell is on display at the Smithsonian Museum of Natural History.
