Renata 357 / SR44W Silver Oxide Button Battery 25-Pack

25-pack silver oxide button cells

This 25-pack supplies Renata 357/SR44W silver oxide button batteries rated at 1.55 volts. Each cell measures 11.6 mm by 5.4 mm and fits devices that require the 357, SR44W, LR44, AG13 or equivalent designations. The silver oxide chemistry provides stable voltage output for precision instruments. The pack is intended for users who maintain multiple devices or want a long-term reserve.

Replaces alkaline LR44 cells

Silver oxide cells last up to five times longer than alkaline equivalents in the same 11.6 mm by 5.4 mm form factor. The upgrade is worth it when a device demands steady 1.55 volt performance over months rather than weeks. Typical beneficiaries include watches, medical thermometers, calculators and small electronic toys that drain alkaline cells quickly. The 25-pack quantity suits households or workshops that replace cells in batches.

Limited to 1.55 volt button format

The 11.6 mm by 5.4 mm size and 1.55 volt rating restrict use to equipment designed for this exact button footprint. Devices requiring higher voltage, larger diameter or rechargeable chemistry cannot use these cells. The chemistry is non-rechargeable, so the batteries must be replaced once depleted. Buyers needing rechargeable packs, higher capacity or different form factors should look elsewhere.
