L1131 vs LR1130: Are They the Same?

Both refer to the thin 11.6 × ~3.0 mm alkaline button family also sold as AG10. They are shopping equivalents — and both are much thinner than LR44.

Are L1131 and LR1130 interchangeable?

Interchangeable for shopping purposes — confirm thickness vs LR44.

Shop by a fresh name-brand pack of the same outline. The retail prefix (DL, ECR, AG, A76) is usually a label, not a new size. Confirm voltage and chemistry before you treat any “almost the same” listing as a drop-in.

L1131 vs LR1130 specs: thickness

They share 1.5 V and Alkaline and 11.6 mm diameter, which is why L1131 vs LR1130 looks interchangeable on a store shelf. Highlighted rows are the ones that change the purchase: thickness.

Read physical fit before capacity. Extra milliamp-hours only help when the holder is built for that cell. A “better” spec in the wrong tray is a mechanical or voltage mismatch, not an upgrade.

Difference between L1131 and LR1130 batteries

If you searched LR1130 vs L1131, you are on the same comparison with the names reversed. The difference between L1131 and LR1130 batteries is not the word “vs” — it is the specs that do not match after you ignore the similar photos.

Thickness — 3.1 mm vs 3 mm

L1131 is 3.1 mm thick; LR1130 is 3 mm. Holders are built for one stack height. The thinner cell loses spring pressure (“works only when I press the cover”). The thicker cell jams the door or bends the clip.

How the size code works (L1131 vs LR1130)

Coin and button codes are rulers, not brand slogans. The letters mark chemistry class. The digits encode size. L1131 measures 11.6 × 3.1 mm; LR1130 measures 11.6 × 3 mm. Once you read the code that way, LR1130 vs L1131 stops looking like a preference and starts looking like a fit check.

Can I use a L1131 instead of a LR1130?

Usually yes. L1131 and LR1130 belong in the same holder class when voltage, chemistry, and outline match. Use a fresh name-brand pack.

If the spent cell said LR1130, L1131 is the correct replacement only when the spec table shows the same size and voltage. A similar prefix (LIR, ML, BR, 14500) is not this swap.

Can I use a LR1130 instead of a L1131?

Usually yes — it is the same pair in the other order. LR1130 vs L1131 does not change fit or voltage.

Buy the fresher authentic pack. Counterfeit retail wrappers are a bigger risk than the extra letter on the can.

Brand labels and aliases

Retail packs hide the IEC size behind house codes. L1131 also appears as LR1131, SG10. LR1130. Those prefixes do not change the outline unless the chemistry letters change (BR, LIR, ML, PR).

How to identify L1131 versus LR1130

You do not need a full datasheet to settle L1131 vs LR1130. You need the stamp, the tray, or a cheap pair of calipers. A store bin labeled only “button cell” or “3V lithium” will not do that work for you.

  1. Read the code on the old cell: L1131, LR1130, and the brand prefixes that map to each one.
  2. If the print is worn off, check the tray, battery door, or user manual before buying.
  3. Measure diameter if the codes are gone: L1131 is 11.6 mm; LR1130 is 11.6 mm.
  4. Measure thickness: L1131 is 3.1 mm; LR1130 is 3 mm.
  5. Buy the matching code. Extra capacity or a thicker can only helps when the holder is built for that cell.

Choose L1131 when…

  • Listing or tray says L1131

Choose LR1130 when…

  • Manual says LR1130 / AG10

Compatibility and substitution

Measure height if the only cells in the drawer are LR44 — diameter alone will mislead you.

Do not stack cells, grind a can, or use foil as a permanent spacer to fake LR1130 with L1131. Read the stamp, then the spec table. If the door will not close without force, you have the wrong height or diameter.

L1131 vs LR1130 FAQ

Is L1131 a lithium cell?

No. Consumer L1131 listings are 1.5V alkaline. CR1130 is the 3V lithium look-alike name.

I searched LR1130 vs L1131 — is this the right page?

Yes. L1131 vs LR1130 and LR1130 vs L1131 are the same pair. Fit, voltage, and chemistry do not change when you flip the order.

Should I always trust a cross-reference chart?

Use this guide as a starting point, then confirm voltage, chemistry, and physical size with your device manual or the marking on the old cell.
