Purpose and Fit

The Energizer 357BPZ is a 1.5 V silver-oxide coin cell sold as a single unit. It suits watches, calculators and small medical devices that require the 357 size and low-drain chemistry.

Capacity and Limits

Rated at 138 mAh, the cell delivers steady voltage for low-drain loads such as timekeeping or memory backup. It is not designed for high-drain applications like LED flash units or motor-driven toys where capacity would deplete rapidly.

Cross-Reference Utility

The packaging lists equivalents including 280-03, 280-08, 303/357, SB-A9, SR 1154 SW and SR 44 SW codes. This lets buyers match the cell to existing device markings without guessing the correct replacement.

Questions about this item

Will this 357 silver-oxide cell replace the SR44SW in my vintage watch movement?

Yes — the cross-reference list includes SR44SW, SR44W, 303/357 and 280-03/280-08, so it fits any device specifying those codes.

How can I confirm the 1.5 V output is stable after installation?

Measure open-circuit voltage with a multimeter; a fresh cell reads at or above 1.5 V DC and holds that level under the low-drain load typical of watches and calculators.

Does the single-unit pack contain only the bare 357 cell or any extra hardware?

The 1-pack supplies one silver-oxide coin cell only — no holder, adapter or tools are included.
