Murata 391 Battery Silver Oxide Watch Battery 1.55V (formerly SONY)

Murata Manufacturing purchased SONY battery manufacturing business in 2017. Effective 2019 SONY branded micro batteries ceased and are now marketed under the Murata brand name.

Sony was the first Corporation to provide the first mercury free silver oxide battery to consumers. Silver oxide batteries are primary cells that have a high energy/weight ratio. Silver oxide is used as the positive electrode (cathode) while zinc is used as the negative electrode (anode) with an alkaline electrolyte. Silver oxide batteries provide an extremely high quality, compact battery for the high performance devices today. Murata (formerly Sony) ensures consistent reliability and performance in every cell. While Silver Oxide batteries are known for mainly wrist watches the application usage due to the high energy density and discharge characteristics have given the cells a broad range of application usage. Please read and observe the following precautions thoroughly. Improper battery handling may cause leakage, heating, explosion of the battery, which may lead to injury or product failure. Never charge the battery. Charging the battery may cause decomposition of the battery electrolyte or increase of the battery internal pressure. Leakage, heating, explosion of the battery may be caused as a result of it. Keep away from infants. If infant happened to swallow the battery, consult a doctor immediately. Do not heat or disposed in fire or disassemble the battery. When the battery is stored or disposed, isolate positive (+) and negative (-) terminals of the battery to avoid those terminals touch each other.
