LR44 Batteries

LR44 Button Cell BATTERIES

LR44A76, or AG13 are the most common type of button cell batteries. They are manufactured in large quantities, and are available from nearly every battery manufacturer. LR44 button cells are used in electronic toys such as Hexbugs, calculators, LED lights in wheel nuts on cars, and just about every other place that a small amount of electricity is required at a low cost.

All LR44 cells have a standard voltage of 1.5V, and size of 11.6mm in diameter by 5.4mm in height. As an Alkaline battery they are inexpensive to produce. This allows for really cheap prices to end users. The multitude of battery suppliers has resulted in many different names for the LR44 battery, including A76AG13, G13, L1154, V13GA, plus many more.

In low-drain applications such as watches and calculators a SG13 button cell (also called SR44, 357 or EPX76) can be used to replace the LR44 button cell. This Silver Oxide battery will last much longer than the alkaline version.
