Sony Batteries are now Murata Batteries

Sony Micro Batteries, (SR, LR, CR) button & coin cells were permanently discontinued in 2019, along with all other Sony branded batteries. Sony had been the world leader in silver oxide watch batteries for many years, owning a world market share in excess of 40%. Sony was known as the leading supplier of watch batteries to many of the world’s leading watch movement manufacturers, including Citizen, Seiko, Casio, Orient and Epson.





Beginning in 2016, Sony sold its battery manufacturing facilities to MuRata Manufacturing, a Japanese electronics component manufacturer with over USD 14 billion in annual sales. Since Sony’s brand withdrawal from the battery market, MuRata has introduced its own line of MuRata branded batteries to replace Sony in the market. The MuRata line-up for SR, LR and CR button and coin cells encompasses the same complete product line. The MuRata batteries continue in the same tradition as the Sony batteries they replace, as one of the best quality button and coin cells available to consumers and manufacturers. Micropower Battery Company has been a master distributor of Sony branded batteries since 1993, distributing to North and South America and today continues with its representation of the MuRata brand.


Our inventory of Sony micro batteries is exhausted, and has been fully replaced with MuRata batteries as a direct replacement. The entire MuRata primary battery product line; silver oxide button cells, alkaline button cells and lithium manganese dioxide coin cells is available in retail/wholesale trade packaging.
