The Energenie LR44 is a set of four alkaline batteries designed for small electronic devices that require a steady 1.5 V power source. With a nominal capacity of 150 mAh, these single-use cells are commonly used to keep calculators, wristwatches, children's toys, and compact remote controls functioning reliably. Each battery is compact, measuring 11.6 mm in diameter and 5.4 mm in height, which allows them to fit into tight compartments without adding significant weight, as a single cell weighs only 1.86 g. Because they are also compatible with AG13 and A76 formats, you can easily use them across various small gadgets that share these standard dimensions.
