I also look at whether the battery is silver oxide, since that usually gives me more stable performance and longer life.
Why I Pay Attention to Voltage and Size
I never assume all watch batteries are the same. Even a small difference in size or voltage can affect how well the battery fits and how my watch performs. Before buying, I compare the battery code on my old battery or check the device manual. That helps me avoid buying the wrong one.
