Duracell Inc. is an American manufacturing company owned by Berkshire Hathaway that produces batteries and smart power systems. The company has its origins in the 1920s, through the work of Samuel Ruben and Philip Mallory, and the formation of the P.R. Mallory Company.
Through a number of corporate mergers and acquisitions, Duracell came to be owned by the consumer products conglomerate Procter & Gamble. In November 2014, P&G reached an agreement to sell the company to Berkshire Hathaway through a transfer of shares. Under the deal, Berkshire Hathaway exchanged the shares it held in P&G for ownership of the Duracell business.
