This LRV08 size battery consists of eight small alkaline cells bundled together to provide a nominal capacity between 40 and 52 mAh, making it a reliable choice for low-drain electronics like remote controls for garage doors or security systems. Measuring 28.5 mm in height and 10.3 mm in diameter, this compact cell weighs just 7.92 g, allowing it to fit easily into small battery compartments without adding bulk.
