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.

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.

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.
