Energizer

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. This acquisition was finalized in January 2019 after a lengthy regulatory approval process. In November 2018, Energizer also purchased the global auto care division from Spectrum (brands which include Armor All, STP, and A/C Pro).
