- description
The LR44 is the cell that red dots and holosights run on, usually two or four at a time, and the reason it is worth buying in a pack of ten is that an optic with a flat battery is a dead optic mid-game.
The naming is the confusing part. This same cell appears as AG13, G13, L1154, V13GA, A76, 1166A, AG-13, FM28F, GP76A, KA76, RW82, LR154, 157, 303 and 357 depending on who made the device. If your manual lists any of those, this is the cell.
The specification is 1.5 volts nominal, alkaline chemistry, typically 150mAh, with a broadly linear discharge curve — which means the brightness of a sight fades predictably rather than dropping off a cliff.
Dimensions are 11.6mm diameter by 5.4mm high. They are single use and should be disposed of safely. Beyond optics, LR44s turn up in clocks, watches, calculators, thermometers, key fob lights and small toys.

Good to know before you buy
Red dots and holosights usually take two or four of these. A pack of ten is one or two refills plus a spare set.
AG13 and LR44 are the same cell. So are a dozen other codes - check the list if your manual uses an unfamiliar one.
Frequently asked questions
Is AG13 the same as LR44?
Yes. So are A76, L1154, V13GA and a dozen other codes, all for the same 11.6 by 5.4mm cell.
How many are in the pack?
Ten.
What uses them in airsoft?
Red dot sights and holosights, usually two or four per optic.
Will the sight dim before it dies?
Yes. The discharge curve is broadly linear, so brightness fades predictably rather than cutting out suddenly.
