The Relentless pursuit of performance excellence

Energizer is forever pushing the boundaries of what's possible in battery technology. This constant passion to innovate has led to some of the highest performing power and lighting advancements ever created. It's what keeps Energizer at the forefront of new thinking, new exploring, new achieving. And it's what keeps Energizer consumers forever confident that the devices they rely on always have the power to surpass expectations.

Energizer powers possibility

The more the rest of the world says it can't be done, the more Energizer scientists are motivated to get it done. "There's no such thing as a zero-mercury alkaline battery." So Energizer created one. "It's impossible for batteries to hold power for up to 10 years when not in use." So Energizer was a pioneer in developing the technology. "Manufacturing batteries using recycled batteries demands a compromise in power and durability." So Energizer created our longest-lasting AA and AAA alkaline batteries – made with 4% recycled batteries. "You can't protect batteries against leaking." So Energizer created the first no-leak guarantee. Much like our iconic Energizer Bunny, our passion for innovation just keeps going and going…

Innovation - with a purpose.

Our passion to improve is driven by our consumers' need for reliability, longevity, responsibility and enjoyment from the devices that impact their lives. From toys to flashlights to cameras to hearing aids, today's technology is woven into the fabric of our daily lives; Energizer powers those devices and empowers those activities that make day-to-day life more complete and satisfying…for as long as technologically possible.
