LR44 battery equivalents
LR44, AG13, A76, 357, 303 and SR44 all fit the same slot. Energizer sells its A76 (an LR44) as a replacement for 157, 303, 357, AG13, EPX76, LR44, S76, SG13 and SR44.[1 · Oct 29, 2026] The difference is chemistry: LR44 is alkaline, SR44 (357/303) is silver oxide.[2 · Oct 29, 2026][3 · Oct 29, 2026]
LR44 vs SR44 (357/303) side by side
| LR44 (Energizer A76) | SR44 (Energizer 357/303) | |
|---|---|---|
| Chemistry | Alkaline (manganese dioxide)[2 · Oct 29, 2026] | Silver oxide[3 · Oct 29, 2026] |
| Nominal voltage | 1.5 V[2 · Oct 29, 2026] | 1.55 V[3 · Oct 29, 2026] |
| Typical capacity | 175 mAh to 0.9 V[2 · Oct 29, 2026] | 150 mAh to 1.2 V[3 · Oct 29, 2026] |
| Typical weight | 1.85 g[2 · Oct 29, 2026] | 2.3 g[3 · Oct 29, 2026] |
| Standard names | IEC LR44, ANSI/NEDA 1166A[2 · Oct 29, 2026] | IEC SR44, ANSI 1131SO[3 · Oct 29, 2026] |
| Size | 11.6 mm across × 5.4 mm thick, maximum (0.457 × 0.213 in)[3 · Oct 29, 2026] | |
The two capacity figures use different cut-off voltages (0.9 V and 1.2 V), so they aren't a like-for-like runtime comparison.
Which one should I buy?
- Toys, calculators, small gadgets: Energizer lists its A76 for watches, toys, calculators and medical devices.[4 · Oct 29, 2026]
- If the manual or old battery says SR44, 357 or 303: buy that. Energizer's guide lists 357/303 for toys, games, books, medical devices, electronics, sporting goods and pet collars.[4 · Oct 29, 2026]
- The A76 bulges as it discharges but, Energizer says, stays within the maximum height on its drawing.[2 · Oct 29, 2026]
- Keep them away from children. Button batteries stuck in the esophagus can cause severe damage in just 2 hours. If one is swallowed, call the National Battery Ingestion Hotline at 1-800-498-8666 right away.[5 · Oct 29, 2026]
Other names you'll see on the pack
Energizer's cross-reference adds V13GA, 4276 and KA76 for the A76, and SR44W, V357, V303, SG13 and GS13 for the 357/303.[4 · Oct 29, 2026] AG13 is a name many packs use; Energizer lists it among the batteries the A76 replaces.[1 · Oct 29, 2026]
