Review: Watch batteries that just work - When I stocked the break room with this Murata 364 pack, it was for the wall clock over the dumbbell racks and a couple of cheap stopwatches my trainers use for intervals. Our old batteries died halfway through a leg day class and that was annoying. Swapped these in and the clock’s been dead-on for weeks, plus the stopwatch hasn’t glitched once during EMOMs. i like that I don’t have to think about them after installing. One small box, toss it in the drawer, problem solved. what really made me glad was not having staff yell “timer died” in the middle of a session. ## Features - 364 SR621SW 1.55V Silver Oxide Button Cell Watch Battery, 18mAh - Continuing the long tradition of Japanese quality micro batteries with high performance and reliability - For use in popular devices such as remotes, car keyfobs, medical devices, and wearables - -10℃ to 60℃ Operating Temperature & excellent self-discharge performance - Made in Japan, 0% Mercury.
