Silver Oxide Chemistry for Steady Voltage

These Duracell 377/376 button cells use silver oxide chemistry to deliver a stable 1.55 volt output across their service life. The 6.8 mm by 2.65 mm form factor fits devices designed for this size. They arrive on a card for easy handling and storage.

Single Cell Voltage Limits Series Use

Each cell provides 1.55 volts and cannot be combined to reach higher voltages without a holder and wiring. The chemistry suits low drain applications such as watches, calculators and small medical devices. Higher current draws will reduce the effective capacity of the cell.

Card Packaging Protects Contacts

The card keeps each battery separated, preventing accidental short circuits between the positive and negative faces. Equivalent references include SR626SW, LR626, AG4 and many numeric codes such as 376, 377, 626 and 606. This helps match replacements across different brand markings.

Questions about this item

Should I pick the 377 or the 376 version on the card?

Both designations refer to the same silver-oxide cell; the card supplies batteries that meet either 377 or 376 specifications.

What does the 1.55 volt rating deliver in a watch or calculator?

It provides the stable 1.55 V output that silver-oxide chemistry maintains through most of its life, keeping timekeeping and display functions accurate.

Which devices does the SR626SW equivalent fit?

The cell matches the SR626SW size of 6.8 mm by 2.65 mm, so it fits any device designed for that standard button-cell footprint.
