The Sony 364 Watch Battery is a low draining silver oxide button cell that is ideal for replacement in compact low-drain continuous use devices. With a silver oxide composition, the 364 / SR621SW coin cell has a low self-discharge and stable output voltage that lasts over the course of its service life, which is not the case with either alkaline or lithium button cells. This watch battery is the perfect fit for small and compact devices that require a low-drain in order to function over long periods of time, examples include the use of the 364 in watches, calculators, small electronic devices, keyless remote entry systems for cars and homes, digital thermometers, glucometers, and heart-rate monitors. Plus, with a shelf-life of 4-6 years, this battery is perfect for purchase in bulk quantities.
