10-Pack Silver Oxide Button Cells
This pack supplies ten Renata 357 / SR44W silver oxide button batteries, each delivering a nominal 1.55 V. They suit watches, calculators, medical devices and other small electronics that require a stable voltage in the 11.6 mm x 5.4 mm form factor. The chemistry provides a flatter discharge curve than alkaline alternatives, helping sensitive circuits maintain accuracy. Buyers needing rechargeable cells or higher capacity formats will not be served by this product.
Sustained voltage stability
Silver oxide chemistry maintains output voltage much more consistently over the cell's life than alkaline equivalents, which decline steadily under load. The manufacturer states these cells last five times longer than the alkaline alternative in typical continuous-use scenarios. This makes them reliable for devices that draw low current for months or years without interruption. Applications demanding very high pulse currents or rapid recharge cycles fall outside the intended use.
Compatibility across common designations
The cells match a long list of industry codes including 357, SR44W, SR44, LR44, AG13, GPA76, 675A, RW82, 303 and several others, simplifying replacement across brands. Physical dimensions of 11.6 mm diameter by 5.4 mm height are standard for this class, so they fit holders designed for any of the listed equivalents. Devices requiring a different voltage, chemistry or footprint cannot use these batteries.

Questions about this item
Does the 1.55 V silver-oxide chemistry keep its voltage stable under continuous daily use?
Silver-oxide cells hold a steady 1.55 V through most of their life, avoiding the gradual drop seen with alkaline types.
What device compartment size matches the 11.6 mm x 5.4 mm dimensions?
The 11.6 mm diameter and 5.4 mm height fit any holder built for 357, SR44W or LR44 size cells.
Can these replace the SR44W and 357 cells already in my older watches and calculators?
Yes — they are direct equivalents for SR44W, 357, SR44, LR44 and all other codes listed for this size.
