Reliable 1.55 V Silver Oxide Power

This pack contains five Energizer 371/370 SR920SW silver oxide button cells rated at 1.55 volts. They are supplied new with a factory-fresh shelf life of up to 10 years and a reported failure rate below 1/1000 of 1%. The chemistry delivers steady voltage for quartz watches and similar low-drain devices.

Ideal for Popular Watch Brands.

These cells suit owners of Swatch, Fossil, Timex and Casio watches that specify the 371/370 size. They also fit keyless entry remotes, small electronics and hearing aids requiring the same dimensions. Buyers who need rechargeable cells or higher current output for power-hungry applications should look elsewhere.

The five-unit pack lets you replace a depleted cell immediately and keep the remainder sealed until needed. Long shelf life means the spares stay reliable for years without special storage. No additional accessories or software are included with this battery-only package.
