Three-pack for small devices

This pack contains three Energizer 357/303 silver-oxide button cells rated at 1.5 volts. They are designed for keyless entry fobs, calculators, watches and similar low-drain electronics that require a compact power source.

Replaces many legacy codes

Each cell substitutes for sizes such as 280-03, 280-08, 303/357, D303/357, SB-A9, SR1154SW, WS14 and SR44SW. The upgrade is worthwhile when a device calls for any of those designations and a mercury-free, long-storage alternative is preferred.

Fits slim compartments, frees drawer space

The button format slides into tight battery bays without adapters. A three-count pack covers multiple devices or spares, and the five-year storage life means unused cells stay ready without frequent replacement cycles.
