SR44 vs LR44
Both are 11.6mm x 5.4mm coin cells, but an SR44 (silver oxide) holds a steadier 1.55V and is the better choice for watches. An LR44 (alkaline) works for low-drain devices but runs down faster.
| SR44 | LR44 | |
|---|---|---|
| Diameter | 11.6mm | 11.6mm |
| Thickness | 5.4mm | 5.4mm |
| Voltage | 1.55V | 1.5V |
| Chemistry | Silver oxide | Alkaline |
| Capacity | ~175mAh | ~118mAh |
What batteries are equivalent to the SR44?
The SR44 is interchangeable with any cell of the same diameter, thickness and voltage, so an equivalent can be substituted without changing the device. Buyers look these cells up under three numbering systems at once — IEC, ANSI and manufacturer codes — and the list below covers the names the SR44 is sold under.

Where is the SR44 battery used?
The SR44 is used in watches, calculators, medical devices and other compact devices that draw small currents over long periods. Its 1.55V output and 175mAh capacity suit equipment that has to run for months without a battery change. The blocks below set out what to check for each device type.
SR44 Watch Battery
The SR44 is a common watch battery cell. Match the model number on your old cell (SR44 = SR44W = 357 = 303) to the one you replace it with — same size and voltage means an easy swap.
What do buyers ask about the SR44 battery?
Need the SR44 priced, or the same cell printed and packed under your own brand? Send the quantity, the target market and the packaging format, and we return price, MOQ band and the SR44 data sheet.
Printed, blister-carded and boxed in our own plant, from 50 cartons per product line. Samples are available before a production run — tell us the device the cell goes into.
