What is an LR44 Battery?
An LR44 battery is a small, round 1.5V power source that measures 11.6mm wide and 5.4mm tall. In fact, think of it as the coin-sized version of AA batteries.
Most people call it LR44, but its official name is LR1154. Furthermore, this power source operates hundreds of small devices in your home.

Understanding LR44 Battery Name System
The “LR44” designation follows a simple system. Specifically:
- L = Alkaline chemistry
- R = Round shape
- 44 = Size code (11.6mm wide, 5.4mm tall)
How LR44 Battery Works
Inside every LR44 battery, zinc gives up electrons while manganese dioxide takes them. Additionally, this exchange creates electricity that powers your devices.
Here’s what happens: Your battery starts at 1.5V when fresh. Subsequently, voltage slowly drops to 0.9V as the power source dies. Importantly, this gradual decline is normal for alkaline types.
Temperature affects its performance more than you think. Moreover, cold weather cuts power by 10% for every 10°C drop. As a result, that’s why your camera dies faster in winter.
