48-Pack Silver Oxide Button Cells

This 48-pack supplies Duracell 364 silver oxide button batteries for watches, calculators and small medical devices. Each cell delivers 1.55 volt nominal voltage in a 6.8 mm by 2.1 mm form factor. The bulk quantity suits technicians, retailers or households that replace coin cells regularly. Buyers who need rechargeable coin cells or a different chemistry should look elsewhere.

364 / SR621SW Cross-Reference

The decisive specification is the 364 / SR621SW designation, which matches a long list of equivalent codes including SR621W, V364, GP364 and 280-34. If the device manual or old cell shows any of those numbers, this pack is the correct replacement. If the required code is absent from the list, the cells will not fit or function properly.

Stable Voltage, Low Self-Discharge

Silver oxide chemistry provides a flat discharge curve so voltage remains steady until the cell is depleted. The 1.55 volt output suits precision instruments that are sensitive to voltage sag. Self-discharge is minimal, so the 48 cells retain charge during extended storage. No heat or noise is generated in normal use.

Questions about this item

How long will the 1.55 volt output last in a watch or medical device?

Silver oxide chemistry holds a steady 1.55 volts for the life of the cell, so voltage does not sag as the battery drains, giving predictable runtime in watches, glucose meters and other low-drain devices.

Are these 364 / SR621SW cells interchangeable with the LR60 or SR620 equivalents listed?

Yes, the 364 / SR621SW size matches all listed equivalents including LR60, SR620, 621, 364A, V364 and 280-34, so any device specifying those codes will accept this pack.

Will the 6.8 mm by 2.1 mm dimensions fit the battery compartment of my device?

The cells measure 6.8 mm diameter and 2.1 mm height, the standard 364 / SR621SW footprint, so they fit any compartment built to that IEC size.
