“Our customers aren’t thinking about batteries when they buy our watches, but they all have expectations for battery life. It’s our responsibility to provide the longest lasting batteries that the market can provide. That’s why I use Sony hundreds of times a day.”

Director, Freestyle Brands

“We have performed thousands of watch battery exchanges using only Sony batteries because my customers deserve longer lasting batteries.”

“Having sold millions of watch batteries to a wide variety of customers, we have grown to become a reliable source for honest and accurate information regarding the quality of the products we sell while striving to provide our customers with the best products in all categories at a great value. This recently became more of a challenge when customers were reporting shorter than expected battery life and battery leakage issues. After noticing a pattern with a particular watch battery brand, the decision to switch to Sony became a no-brainer. Sony’s long-lasting battery performance and antileakage technology allows us to offer our customers a battery that has them coming back wearing smiles, not looking for excuses.”

Steve Krohn, President, The BatteryXperts, Inc.

Sony’s manufacturing facility, technology and team of battery engineers (including the inventor of the mercury free silver oxide battery) was acquired by Murata in 2017. We are selling the same batteries under the Murata brand, in exactly the same packaging.
