LR44 vs LR1130: Same Diameter, Different Thickness

LR44 (AG13/A76) and LR1130 (AG10/L1131) share an ~11.6 mm diameter and 1.5V alkaline chemistry, but LR44 is 5.4 mm thick while LR1130 is only ~3.0 mm. Mixing them up is one of the most common button-cell shopping errors.

Are LR44 and LR1130 interchangeable?

Not interchangeable — match thickness as well as diameter.

A LR1130 vs LR44 swap fails on thickness, capacity. If the door only closes when you force it, or the device works only while you press the cover, you have the wrong cell — not a weak spring you should ignore.

LR44 vs LR1130 specs: thickness, capacity

They share 1.5 V and Alkaline and 11.6 mm diameter, which is why LR44 vs LR1130 looks interchangeable on a store shelf. Highlighted rows are the ones that change the purchase: thickness, capacity.

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 LR44 and LR1130 batteries

If you searched LR1130 vs LR44, you are on the same comparison with the names reversed. The difference between LR44 and LR1130 batteries is not the word “vs” — it is the specs that do not match after you ignore the similar photos.

Thickness — 5.4 mm vs 3 mm

LR44 is 5.4 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.

Capacity — 110–130 mAh vs 70–80 mAh

Typical LR44 capacity is 110–130 mAh. LR1130 is 70–80 mAh. Runtime only follows that gap inside the correct holder. Extra capacity in the wrong tray does not last longer — it often does not run at all.

How the size code works (LR44 vs LR1130)

Coin and button codes are rulers, not brand slogans. The letters mark chemistry class. The digits encode size. LR44 measures 11.6 × 5.4 mm; LR1130 measures 11.6 × 3 mm. Once you read the code that way, LR1130 vs LR44 stops looking like a preference and starts looking like a fit check.

Can I use a LR44 instead of a LR1130?

Usually no. LR44 is 11.6 × 5.4 mm at 1.5 V (Alkaline). LR1130 is 11.6 × 3 mm at 1.5 V (Alkaline). Those are not the same part.

If the spent cell or tray said LR1130, specify that code. Forcing LR44 can crack a cover, lose contact, or apply the wrong voltage.

Can I use a LR1130 instead of a LR44?

Usually no. Going the other way does not fix a diameter, thickness, or voltage miss. LR1130 in a LR44 holder has the same problem with the names flipped.

Brand labels and aliases

Retail packs hide the IEC size behind house codes. LR44 also appears as AG13, A76, LR1154. LR1130. Those prefixes do not change the outline unless the chemistry letters change (BR, LIR, ML, PR).

How to identify LR44 versus LR1130

You do not need a full datasheet to settle LR44 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: LR44, 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: LR44 is 11.6 mm; LR1130 is 11.6 mm.
  4. Measure thickness: LR44 is 5.4 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 LR44 when…

  • Tray or old cell says LR44 / AG13 / A76 / 76A
  • Toys, laser pointers, and thicker button-cell gadgets
  • You measured ~5.4 mm height on the spent cell

Choose LR1130 when…

  • Tray says LR1130 / AG10 / L1131
  • Thin calculators, thermometers, and calipers
  • You measured ~3.0 mm height — not a full LR44 stack

Compatibility and substitution

A thin LR1130 in an LR44 holder usually loses spring contact. A thick LR44 will not close in an LR1130 door. Do not confuse either with 3V CR1130 lithium cells.

Do not stack cells, grind a can, or use foil as a permanent spacer to fake LR1130 with LR44. Read the stamp, then the spec table. If the door will not close without force, you have the wrong height or diameter.

LR44 vs LR1130 FAQ

Is LR1130 the same as LR44?

No. Same diameter family, different thickness. LR44 is 5.4 mm; LR1130 is about 3.0 mm.

I bought AG10 instead of AG13 — will it work?

Probably not. AG10 maps to LR1130 (thin); AG13 maps to LR44 (thick). Check the number after AG.

What is the silver oxide upgrade for each?

LR44 → SR44/357. LR1130 → SR1130SW/389/390. Upgrade within the same thickness class.

I searched LR1130 vs LR44 — is this the right page?

Yes. LR44 vs LR1130 and LR1130 vs LR44 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.
