LR44 vs LR1130

The LR44 and the LR1130 are both 1.5 volt alkaline button cells 11.6 mm across, which is why they get mixed up in multipacks. Height separates them: the LR44 is 5.4 mm and holds 110 to 130 mAh, the LR1130 is 3.1 mm and holds 50 to 70. They are not interchangeable.

Brand codes hide the difference. The LR44 sells as AG13, A76, L1154 and 157, while the LR1130 sells as AG10, LR54, 189 and V10GA. A bargain assortment pack labelled only with AG numbers puts the two side by side in near-identical blisters, and the 2.3 mm of height between them is hard to judge by eye. Measure the old cell, or read the code stamped on its face, before you buy a replacement.

Fit decides everything. A compartment machined for a 3.1 mm cell will not close over an LR44, and an LR1130 dropped into an LR44 holder usually sits too low for the contact to press, so the device flickers or reads flat. Stacking is not a workaround either: two LR1130s measure 6.2 mm and deliver 3 volts, which is both too tall and too much voltage for a single-LR44 device.

For anything where accuracy or runtime matters, both sizes have a silver-oxide upgrade in the same case. The SR44, sold as 357, replaces the LR44, and the SR1130, sold as 389 or 390, replaces the LR1130. Silver oxide holds a flat 1.55 volts almost until it dies, while alkaline sags steadily, which is why quartz watches and digital calipers behave better on the silver cells.

Frequently asked questions

Is AG13 the same as AG10?
No. AG13 is the LR44, 11.6 by 5.4 mm, and AG10 is the LR1130, 11.6 by 3.1 mm. They share a diameter, so they look alike in an assortment pack, but the LR44 is nearly twice as tall and holds roughly twice the charge. Match the height, not the width.
Can I use an LR1130 instead of an LR44?
Not reliably. The thinner cell leaves about 2.3 mm of gap in an LR44 holder, so the contact often fails to reach it and the device reads dead or cuts out when bumped. Even where a strong spring bridges the gap, you get around half the runtime.
Can two LR1130 cells replace one LR44?
No. Stacked they measure 6.2 mm, taller than the 5.4 mm the compartment allows, and they supply 3 volts where the device expects 1.5. Overvoltage can damage the circuit even if you force the cover shut. Buy the correct single cell instead.
Which lasts longer, LR44 or LR1130?
The LR44, at 110 to 130 mAh against 50 to 70. That is a straight consequence of volume, since both cells use the same alkaline chemistry at the same 1.5 volts. In a device that accepts either height, the taller cell roughly doubles the time between changes.

⚠️ Keep away from children. Swallowed button batteries, especially 20 mm lithium coins, cause severe injury within hours. If a child swallows one, call the 24/7 National Battery Ingestion Hotline (US) at 800-498-8666 or poison control at 800-222-1222 immediately. What every parent should know.
