Description
The Duracell LR54 is a 1.5V alkaline button cell battery supplied in packs of two, measuring 11.6mm diameter by 5.4mm height. Also sold as AG10, 189, V10GA and D189A depending on manufacturer naming conventions, the LR54 powers watches, calculators, small toys, laser pointers, digital thermometers and compact photographic equipment that require a coin-style cell in this size.
Designed for devices with low to moderate current draw, the LR54 alkaline chemistry provides stable voltage output across the discharge curve and retains charge during storage at room temperature. This makes them suitable both for immediate use in a device and as backup stock kept in a drawer or toolbox. The 1.5V nominal voltage matches the requirements of most button-cell-powered electronics designed for this cell size.
Duracell manufactures the LR54 to the same construction standards as its larger alkaline cells, with a steel case, zinc anode and manganese dioxide cathode separated by an alkaline electrolyte. The button format requires precise sealing to prevent leakage in small devices, and the 11.6mm x 5.4mm dimensions fit the standard LR54/AG10 battery compartment found across multiple device categories. Each pack contains two cells individually sealed in blister packaging.

Frequently Asked
What devices use LR54 batteries?
LR54 batteries are used in watches, digital calculators, small LED torches, laser pointers, digital thermometers, glucose meters, small toys and compact photographic equipment. Any device with a battery compartment labelled LR54, AG10, 189, V10GA or D189A will accept this cell.
Are LR54 and AG10 the same battery?
Yes. LR54 is the IEC (International Electrotechnical Commission) designation, while AG10 is the common industry name. The same physical cell is also sold as 189, V10GA, D189A and LR1130 by different manufacturers. All are 11.6mm x 5.4mm, 1.5V alkaline button cells.
How long do LR54 batteries last in storage?
Duracell alkaline button cells retain charge for several years when stored at room temperature in their original blister packaging. Actual shelf life depends on storage conditions — cool, dry environments maximise retention. Once installed in a device, runtime depends on the current draw of that specific device.
Can LR54 batteries be recharged?
No. LR54 alkaline button cells are single-use and must not be recharged. Attempting to recharge an alkaline cell can cause leakage, rupture or other damage. Dispose of used cells responsibly through battery recycling facilities.
