About the LR1130
The 11.6 mm button cell, the same diameter as an LR44 and thinner. That similarity causes real trouble — an LR44 will not sit in an LR1130 holder and an LR1130 in an LR44 holder makes intermittent contact.

Same diameter, different thickness
These are the cells most often confused with a LR1130, because they are exactly as wide and only differ in one dimension.

|---|---|---|---|
| CR1220 | 12 mm | 2 mm | -1.1 mm |
| LR44 | 11.6 mm | 5.4 mm | +2.3 mm |

Frequently asked questions
What size is a LR1130 battery?
11.6 mm across and 3.1 mm thick — 0.46 × 0.12 inches.
What voltage is a LR1130?
1.5 V (Alkaline).
What is another name for a LR1130?
AG10, 389, SR1130, L1131 — all the same cell.
Can I use a CR1220 instead of a LR1130?
They are the same diameter, 11.6 mm, and different thicknesses: 3.1 mm against 2. A CR1220 is thinner, so it may rattle or lose contact, and it holds less. Same voltage, so nothing is damaged by trying.
