25-Pack Silver Oxide Button Cells

This pack contains twenty-five Renata 377 / SR626SW silver oxide button batteries, each delivering 1.55 V. They suit watches, calculators, medical devices and small electronics that require a stable voltage in a 6.8 mm x 2.65 mm form factor. Buyers who need rechargeable cells or higher capacity formats will not be served by this chemistry.

Simple drop-in replacement

Installation is a direct swap: remove the old cell and insert the new one with the correct polarity. The flat profile fits tight compartments, but the 2.65 mm thickness leaves no margin for bent contacts or corroded holders. Misalignment or debris in the battery bay are the common causes of poor connection.

Silver oxide voltage limits

The 1.55 V output stays steady until near depletion, unlike alkaline equivalents that sag early. However, the chemistry cannot supply high pulse currents, so devices with motors, bright LEDs or radio transmitters may brown out. The pack size of twenty-five suits regular maintenance but not high-drain continuous use.

Questions about this item

How can I confirm the 1.55 V silver-oxide cells are working after installation?

Use a multimeter to read 1.55 V across the terminals; the device should power on steadily without voltage sag.

What comes in the 25-piece pack and what must I buy separately?

The pack contains 25 Renata 377/SR626SW cells measuring 6.8 mm x 2.65 mm; no charger or holder is included.

Which of the listed equivalents — 377, SR626SW, AG4 or 376 — should I choose for my watch?

All listed codes refer to the same 1.55 V 6.8 x 2.65 mm silver-oxide cell; pick the code your device manual specifies.
