Duracell 370/371 Silver Oxide Button Battery

Duracell is one of the most recognized battery brands globally, known for its long-lasting power and iconic 'Copper Top' branding. This specific product is a 370/371 silver oxide button cell battery, commonly used in watches and small electronics. The brand's history dates back to the early 1920s when scientist Samuel Ruben and manufacturer Philip Rogers Mallory partnered to create the P.R. Mallory Company.

While the brand has changed hands several times over the decades—including ownership by Gillette and later Procter & Gamble—it is currently a wholly owned subsidiary of Berkshire Hathaway, the multinational conglomerate led by Warren Buffett. Manufacturing for Duracell products occurs at various facilities worldwide, including major plants in the United States, Belgium, and China to serve global demand.
