History #

The LR44 battery is a small, cylindrical battery that is commonly used in small electronic devices. It was first developed in the 1950s by the Japanese company Nippon Electric Company (NEC). The LR44 was one of the first alkaline button cells to be developed and is still in use today.

Typical Chemistry #

The LR44 battery is an alkaline battery, which means it contains a mixture of alkaline electrolytes and a zinc anode. The electrolytes are typically potassium hydroxide and sodium hydroxide, while the anode is composed of zinc and manganese dioxide. The LR44 battery has a nominal voltage of 1.5 volts and a capacity of about 150 mAh.

Typical Use #

The LR44 battery is commonly used in small electronic devices such as watches, calculators, and remote controls. It is also used in some medical devices, such as hearing aids and glucose meters. The LR44 battery is also used in some toys and games, such as laser pointers and electronic dart boards.

Design #

The LR44 battery is a small, cylindrical battery that measures 11.6 mm in diameter and 5.4 mm in height. It has a positive terminal at the top and a negative terminal at the bottom. The LR44 battery is designed to be used in small electronic devices and is not suitable for use in larger devices. The LR44 battery is also designed to be used in low-drain applications, such as watches and calculators, and is not suitable for high-drain applications, such as digital cameras.
