50-pack silver-oxide button cells
This pack contains fifty Renata 357/SR44W silver-oxide button batteries, each delivering a steady 1.55 volt output. The cells measure 11.6 mm by 5.4 mm and suit watches, calculators, medical devices and small electronics that require reliable low-drain power.
Replaces alkaline LR44 and SR44 types
The silver-oxide chemistry lasts about five times longer than alkaline equivalents such as LR44 or AG13, so the upgrade is worthwhile for devices changed infrequently or where voltage stability matters. It also covers legacy designations including 357A, D357, V357, GP357, GPA76, PX76A and numerous other cross-reference codes.
Limited to low-drain 1.55 V applications
These cells are not rechargeable and cannot supply the current needed for high-drain gadgets such as LED torches or motorised toys. They must only be used in equipment designed for a single 1.55 volt silver-oxide button cell of this physical size.
