Duracell Inc. is an American manufacturer of alkaline batteries, specialty cells, and rechargeables; it is a wholly owned subsidiary of Berkshire Hathaway since 2016.

Through a number of corporate mergers and acquisitions, Duracell came to be owned by the consumer products conglomerate Procter & Gamble (P&G).

In November 2014, P&G reached an agreement to sell the company to the international conglomeration Berkshire Hathaway through a transfer of shares.

[8] In March 2012, along with Powermat Technologies, Duracell, under the Procter & Gamble corporate umbrella, founded the Power Matters Alliance (PMA), an alliance of leading industry and governmental organizations that is dedicated to advancing smart and environmentally sound wireless power.

[14] The transfer was completed on February 29, 2016, with P&G investing $1.8 billion in cash into Duracell, and Berkshire Hathaway giving P&G back 52 million shares.

[16] The deal culminated with the vertical air intake of the car designed like a Duracell battery, which was first introduced in the 2022 Miami Grand Prix.

Lesser-used sizes such as AAAA (primarily for pagers, penlights, and blood glucose meters) and J size batteries (for hospital devices and photographic strobe flash units) are also manufactured and a range of "button cells" using zinc-air, silver-oxide, and lithium chemistries, used in calculators, watches, hearing aids, and other small (mostly medical-related) devices.
