Size:1 Pack The high volumetric energy density of Duracell silver oxide button
cells, and their ability to deliver this energy at relatively high current
drains, makes them ideal for miniature devices where space is limited. Silver
cells also have an extremely stable discharge voltage, good shelf life, and
the ability to operate over a wide temperature range. This 1.5-volt silver
oxide battery is primarily used to power watches, thermometers, handheld games
and calculators.
