20-pack alkaline button cells

This pack contains 20 SR621SW alkaline button cells, each rated at 1.5 volts and 25 milliamp_hours. They are built to power watches, calculators and similar low-drain devices. The cells arrive fresh with a full charge and a three-year shelf life.

Capacity and headroom

A single cell delivers 25 milliamp_hours at 1.5 volts, which is sufficient for continuous watch operation over several years. The alkaline chemistry provides stable voltage for low-drain loads but will deplete quickly if used in higher-drain applications such as LED lights or motorised toys.

Equivalent model list

The cells are direct replacements for LR621, D364, SP364, 602, 164, 280-34, SB-AG/DG, SR60, SR60L, SR621, GP364, T, V364 and other listed cross-references. They are not suitable for devices that require silver-oxide chemistry or higher capacity ratings.

Questions about this item

Will these SR621SW cells run in a watch that currently takes an AG1 or 364?

Yes, the pack is listed as compatible with AG1, 364, LR621, D364, SR60, SR621 and several other common codes used by Swatch, Fossil, Timex and Casio models.

How can I check the cells are fresh and delivering full voltage after opening the blister?

Each cell should measure 1.5 volts on a multimeter; the supplier states they ship with a full 1.5 V charge and a three-year shelf life from 2006-era production standards.

What exactly comes in the box and do I need anything else to use them?

You receive 20 SR621SW alkaline button cells arranged as two 10-count blister cards; no charger, adapter or extra hardware is required — just insert the cell matching your device’s polarity.
