## Murata LR1120 (AG8 / 191) 1.55V Alkaline Watch Battery – Pack of 10

Murata LR1120 is a genuine 1.55V alkaline button cell, commonly cross-referenced under the code AG8 / 191. It is manufactured by Murata and is designed for small watches, laser pointers, calculators, and compact torches. This listing is for 10 x LR1120 batteries only.

### Benefits

Fitting the correct battery chemistry and voltage matters more than people often expect: an incorrect substitute can run a watch fast, slow, or shorten the life of the movement. The LR1120 is matched to the AG8 / 191 specification so your watch keeps time the way its manufacturer intended. Alkaline button cells offer a steady, dependable voltage for lower-drain devices and are generally a cost-effective option.

### How to Confirm Fit

Watch batteries of the same physical size are sometimes sold under different code names by different manufacturers, since there’s no single universal numbering system across the industry. Before ordering, check the code stamped on your existing battery or printed inside your watch’s battery hatch, and match it against AG8 / 191. If your old battery shows a different code, compare the physical diameter and thickness against the LR1120 rather than relying on the code name alone.

### Fitting Guidance & Safety

Many watches with a screw-off or snap-off case back can be opened at home with a small case-back tool, but we’d suggest a jeweller or watch specialist if you’re not confident, especially on water-resistant models, since disturbing the seal can affect water resistance until it’s re-tested. Handle button cells by the edges, avoid letting metal tools touch both terminals at once, and keep spare cells away from children and pets, as they are a swallowing hazard.

### Important Information

This listing covers the battery only; it does not include a watch, tool kit, or case-back opener. For chronographs, smartwatch hybrids, or any watch with additional electronic functions, please confirm with your watch’s manual that the LR1120 is the correct specification for that movement, as some multi-function watches are calibrated for a specific drain rate.
