Setup, Compatibility & Care
To install, ensure your device is powered off or, in the case of a watch, the crown is pulled out if applicable. Handle the battery by the edges with non-metallic tweezers to avoid short-circuiting the terminals. Always verify your device manual to ensure the SR927SW or SR57 size is specified. Keep the battery in its original packaging in a cool, dry place until use. If replacing a watch battery, check the integrity of the O-ring seal; if it appears cracked or dry, it may need to be lubricated or replaced to maintain the watch's water resistance.
