LR1130 battery equivalents
The LR1130 is a 11.6 × 3.05 mm silver-oxide cell, used in larger quartz watches, and as the alkaline LR1130 in calculators and toys. It's sold under several names: SR1130SW, SR1130W, 390, 389, AG10, 189, LR54, L1131, SR54.
Equivalents
| Sold as | Type | In a watch |
|---|---|---|
| SR1130SW, 390 | Silver oxide, low drain | Best for an ordinary analog quartz watch |
| SR1130W, 389 | Silver oxide, high drain | Works in any watch, and suits one with a backlight, alarm or chronograph |
| LR1130, AG10, 189, LR54, L1131 | Alkaline, 1.5 V | Fits, but runs down sooner and the voltage sags; use only in a pinch |
| SR54 | Older or alternative codes | Same size; check the chemistry on the pack |
Look-alikes that won't fit
These are also 11.6 mm across, so they look right in the pack, but the thickness is different. They aren't substitutes.
- 366 SR1116SW1.65 mm thick (-1.4 mm)
- 381 SR1120SW2.05 mm thick (-1 mm)
- 344 SR1136SW3.6 mm thick (+0.55 mm)
- 386 SR43SW4.2 mm thick (+1.15 mm)
- LR44 SR44SW5.4 mm thick (+2.35 mm)
Never use a lithium coin cell in its place. Lithium cells run at 3 volts, twice what a silver-oxide watch movement expects.

Questions
- Is 390 the same as 389?
- They're the same size (11.6 × 3.05 mm) and the same silver-oxide chemistry. The 390 (SR1130SW) is the low-drain version for ordinary analog watches; the 389 (SR1130W) is high-drain, for watches with a light, alarm or chronograph. The 389 works in any watch that takes a 390.
- Is LR1130 the same as SR1130SW?
- Same size, different chemistry. LR1130 (also sold as AG10) is alkaline and SR1130SW is silver oxide. The alkaline cell fits, but it holds about 44–70 mAh against 74–85 mAh and its voltage drops as it drains, so a watch runs a shorter time on it.
- Can I use a 344 instead of a LR1130?
- No. Both are 11.6 mm across, but the 344 is 3.6 mm thick and the LR1130 is 3.05 mm. A thicker cell won't let the caseback or holder close, so the watch won't run reliably.
- How long does a LR1130 battery last?
- In a typical analog quartz watch, two to five years. It holds about 74–85 mAh; a running chronograph, a backlight or an alarm drains it faster. Unused cells keep for several years in the pack.
