Coin-cell power for small devices

The Energizer 377BPZ is a silver oxide coin cell rated at 1.5 V, supplied as a single unit. It fits watches, calculators, toys and hearing aids that require this specific form factor. The cell replaces common references such as 376, 377, D377, SR626SW and SR66.

Steady voltage through the discharge cycle

Silver oxide chemistry delivers a flat output curve near 1.55 V for most of the cell's life. This keeps timekeeping and low-drain electronics accurate without the voltage sag seen in alkaline equivalents. The stable plateau lasts until the active material is nearly exhausted.

Direct replacement for listed cross-references

The battery matches the 376, 377, 626 and 6265 size codes called out by the manufacturer. Devices specifying a different coin-cell diameter or chemistry will not accept this cell. Buyers needing higher capacity or a rechargeable option must select a different product.

Questions about this item

How much power does the 1.5 V silver oxide cell deliver during continuous use in a watch or calculator?

The cell provides a nominal 1.55 V and is designed for low-drain devices such as watches, calculators and hearing aids, so it maintains voltage steadily over its service life.

Does the 377BPZ require any additional hardware or adapters to fit devices that take a 376 or SR626SW?

No, the 377BPZ is a direct replacement for 376, 377, D377, SB-AW, SR626SW and SR66 cells, so it fits the existing battery compartment without extra parts.

Will the 1.55 V output work reliably in older equipment originally specified for 1.5 V 377 or 626 size batteries?

Yes, the 1.55 V silver oxide chemistry matches the voltage profile of the legacy 377 and 626 cells, so older devices operate normally with this replacement.
