Duracell 386/301 watch battery

Duracell is a globally recognized American brand synonymous with high-performance power solutions. Originally founded in 1924 as the P. R. Mallory Company, the 'Duracell' brand was officially launched in 1964. The product shown is a Silver Oxide 386/301 button cell battery, commonly used in high-precision devices like wristwatches, calculators, and medical equipment.

While Duracell has a massive global manufacturing footprint—including major plants in the United States and Belgium—its specialty silver oxide watch batteries are frequently sourced from specialized precision manufacturing facilities in Switzerland, a country renowned for its horological and micro-electronic expertise. Since 2016, Duracell has been a wholly-owned subsidiary of Berkshire Hathaway, the multinational conglomerate led by Warren Buffett, ensuring its position as a dominant force in the global portable power market through 2026 and beyond.
