Development of the world’s first mercury-free silver oxide battery in 2004
Historically, mercury has been used in button batteries to reduce hydrogen gas generated inside the battery because the elimination of mercury was considered technically impossible. Murata undertook the challenge of designing mercury-free silver oxide batteries to contribute to the protection of the environment and consumers. Murata successfully introduced the world’s first mercury-free silver oxide batteries in 2004 and went on to develop a mercury-free alkaline manganese button battery in 2009.
Unique manufacturing process for strong anti-leakage performance
Murata’s button batteries have superior anti-leakage performance thanks to its unique sealing material and technology. Our patented “J-shaped gasket” was invented as a unique sealing solution to maintain air pressure inside the battery. Optimization of the gasket shape results in the reduction of leakage risks during long-term storage.
SR Series* Nominal Voltage 1.55V, Operating Temperature Range -10°C to +60°C
