With an 18mAh capacity and a wide operating temperature range (-10°C to 60°C), it delivers stable voltage for precision devices like watches, keyfobs, and medical monitors. Made in Japan with mercury-free, RoHS-compliant materials, this 2-pack offers reliable, leak-resistant power backed by over 40 years of manufacturing expertise. ## Description 40+ years of technology development and manufacturing expertise. 364 SR621SW batteries are the perfect long lasting replacement for all your personal devices including keyfobs, blood sugar monitors, remote controls, digital thermometers, toys, calculators and more. Operating temperature: -10°C to +60°C (standard). Nominal Capacity: 18mAh Review: Reliable 1.55V Power for Watch Maintenance - I purchased this 2 pack of Murata 364 silver oxide batteries to replace the power cell in my watch. Since Murata took over the Sony battery manufacturing line, these are the direct replacements for the original Sony 364 series and offer the same high standards of performance. Technical Performance Analysis Voltage Stability: These cells maintain a consistent 1.55V output. This is critical for precision timekeeping in quartz movements where voltage drops can cause the watch to lose seconds over time. Leak Resistance: Silver oxide chemistry is superior to alkaline for watch applications because it is significantly more resistant to corrosion and leaking, protecting the internal movement of the timepiece. Shelf Life: The batteries arrived with a modern production date and a clear expiration window several years out, ensuring they retain their full charge while stored. Direct Compatibility: These were a perfect dimensional match for the SR621SW specification. They seated firmly into the battery clip without requiring any adjustment to the contacts. Maintenance Recommendation This is an efficient and cost effective way to maintain your own watches without paying a jeweler a premium for a simple swap. Given that it is a 2 pack, it provides a ready spare for future maintenance or for a second timepiece using the same movement. Pros Direct replacement for Sony 364 and SR621SW cells Stable silver oxide chemistry for quartz precision High capacity for long term operation Cons Packaging is small and easy to misplace; store in a marked container Review: It is Sony batteries - The Sony batteries was merged with Murata. I had a hard time finding the old Sony battery I had on my watch and I got to know they have changed the name.
