Full equivalents, what does not substitute, and where it is used." url: https://atoneplace.net/battery/sr1130/ site: "At One Place" --- # SR1130 battery **What replaces a SR1130: 389, 390, SR54, SR1130W, SR1130SW, SR1131** 1.55 V silver oxide, 11.6 × 3.05 mm (diameter × height) The SR1130 is a single-use 1.55 V silver oxide button cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit. ## Specification - **IEC designation:** SR1130 - **ANSI / NEDA:** 1138SO - **Nominal voltage:** 1.55 V - **Chemistry:** Silver oxide - **Size:** 11.6 × 3.05 mm (diameter × height) - **Typical capacity:** 85 mAh - **Rechargeable:** No — never charge it ## Codes that mean the same battery *Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.* | Code | Fits? | | --- | --- | | 389 | Yes — same cell | | 390 | Yes — same cell | | SR54 | Yes — same cell | | SR1130W | Yes — same cell | | SR1130SW | Yes — same cell | | SR1131 | Yes — same cell | | D389 | Yes — same cell | | V389 | Yes — same cell | | 1138SO | Yes — same cell | | GP389 | Yes — same cell | | SB-BU | Yes — same cell | ## Codes that look close but are not | Code | Why it is not a substitute | | --- | --- | | LR1130 / LR54 / 189 | The alkaline cell in the same 11.6 × 3.0 mm can, at 1.5 V with a sloping discharge and 80 mAh against 85. Fine in a toy; wrong in a caliper or a light meter, where the reading depends on a stable supply voltage. | | SR44 / 357 | Same 11.6 mm diameter but 5.4 mm tall. It will not fit, and where three of these stack to make 4.65 V the substitution changes the whole stack. | > The SR1130 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape. ## Where it turns up - Larger quartz watches - Digital calipers and dial indicators - Laser pointers - Medical thermometers ## Common questions ### What is equivalent to a SR1130? 389, 390, SR54, SR1130W, SR1130SW, SR1131, D389, V389, 1138SO, GP389, SB-BU — all the same 1.55 V cell under different manufacturer codes. ### Can I use a LR1130 / LR54 / 189 instead of a SR1130? The alkaline cell in the same 11.6 × 3.0 mm can, at 1.5 V with a sloping discharge and 80 mAh against 85. Fine in a toy; wrong in a caliper or a light meter, where the reading depends on a stable supply voltage. ### Is the SR1130 rechargeable? No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes. ## Related pages - [LR44 battery](https://atoneplace.net/battery/lr44/) - [SR626SW battery](https://atoneplace.net/battery/sr626sw/) - [SR44 battery](https://atoneplace.net/battery/sr44/) - [PR41 battery](https://atoneplace.net/battery/za312/) - [PR48 battery](https://atoneplace.net/battery/za13/) - [SR621SW battery](https://atoneplace.net/battery/sr621sw/) - [PR44 battery](https://atoneplace.net/battery/za675/) - [SR920SW battery](https://atoneplace.net/battery/sr920sw/) - [LR41 battery](https://atoneplace.net/battery/lr41/) - [PR70 battery](https://atoneplace.net/battery/za10/) - [SR927SW battery](https://atoneplace.net/battery/sr927sw/) - [LR1130 battery](https://atoneplace.net/battery/lr1130/) ## Sources - Official vendor product documentation — At One Place (/about/)
