Energizer Holdings, Inc.

A maker of batteries and portable lighting, this company powers everyday gadgets under familiar brands like Energizer, Eveready, Rayovac, and Varta. Its roots stretch to 1896, when Conrad Hubert founded the American Ever Ready Company to sell his invention, the first handheld flashlight. A fun fact: its mascot, the drumming Energizer Bunny, first appeared in ads in 1989.
