Energizer Holdings, Inc. is an American manufacturer and one of the world’s largest manufacturers of batteries, headquartered in St. Louis, Missouri. It produces batteries under the Energizer, Ray-O-Vac, Varta, and Eveready brand names, and formerly owned a number of personal care businesses until it separated that side of the business into a new company called Edgewell Personal Care in 2015.

In January 2018, Energizer announced it was purchasing the global battery and lighting division from Spectrum Brands, which includes the Ray-O-Vac and Varta brands.

The company has its foundation in the Eveready Battery Company, which in 1980 changed the name of its Eveready Alkaline Power Cell to Energizer. In 1986, corporate parent Union Carbide sold Eveready Battery to Ralston Purina. In 2000, Ralston spun off Eveready, and the company was listed on the New York Stock Exchange as Energizer Holdings, Inc.

As of 2021, Energizer has six operational facilities in the United States. It also has a manufacturing facility in Singapore since 1946, supplying the Asia and Oceania markets. Singapore is home to Energizer’s largest international plant, which is also the only Energizer facility outside the United States capable of producing alkaline and lithium batteries.
