Renata 362/361/SR721SW Silver Oxide Button Battery 5-Pack

5-pack silver oxide button cells

This pack contains five Renata 362/361/SR721SW silver oxide button batteries. Each cell delivers a nominal 1.55 volts in a compact 2.1 mm by 7.9 mm form factor. The silver oxide chemistry provides stable voltage output for precision devices. The five-piece quantity suits multi-device households or professional toolkits.

Check device code and voltage before ordering

Confirm that your device specifies a 362, 361 or SR721SW cell and requires 1.55 volts. The battery measures 2.1 mm thick by 7.9 mm in diameter, so verify the compartment accepts those exact dimensions. Cross-reference the listed equivalent codes such as 361, V362, SR720 or AG11 against your manual. Do not substitute if your equipment calls for a different chemistry or voltage.

Low self-discharge suits intermittent use

Silver oxide chemistry exhibits very low self-discharge, so cells retain charge during long storage periods. The stable 1.55 volt output minimises voltage sag in continuous low-drain applications such as watches or medical instruments. No cooling or ventilation is required for normal operation. Dispose of depleted cells according to local regulations for silver oxide batteries.
