LR44 is a common name for a standard type of 1.5 volt button cell alkaline battery, commonly used in small LED flashlights, digital thermometers, clocks, and laser pointers.
The silver-oxide battery variant SR44 has the same outer dimensions and approximately the same nominal voltage as an LR44 cell, but higher energy density. Although LR44 and SR44 are two distinctly different batteries, in common usage they are usually considered the same battery with only a 'quality' difference.
R44 indicates a round (cylindrical) 11.4±0.2 mm diameter and 5.2±0.2 mm height as defined by the British/European standard BS EN 60086:1998, Primary batteries.[1]

IEC code
The first and second letter of this battery code conforms to the alphanumeric coding system defined by the International Electrotechnical Commission (IEC) in its 60086-3 standard (Primary batteries, part 3 Watch batteries). The first letter indicates the electrochemical system used:
- L: (−) zinc electrode – alkali metal hydroxide electrolyte – manganese dioxide electrode (+)
- S: (−) zinc electrode – alkali metal hydroxide electrolyte – silver oxide electrode (+)
The second letter R indicates a round (cylindrical) form.
