Applications

Panasonic SILVER OXIDE SR621 is suitable for precision electronic devices such as digital watches, bike computers, heart rate monitors for athletes, etc. – typical applications where a high-energy density and a stable operating voltage are required. Other applications include laser pens, calculators and digital clocks.

Superior silver

Panasonic SR621 is distinguished by a large capacity and a continuous high power supply till the end of its life cycle. Although the use of silver results in a higher price compared with other button cells or coin type batteries, the long life (twice the capacity of an alkaline button cell) and stability of SR621 make it nevertheless an excellent choice.

Trusted technology for continuous power

Panasonic launched the production of Silver Oxide batteries in Japan back in 1976. Like all our batteries in this range, SR621 uses silver oxide as the positive electrode (cathode), zinc as the negative electrode (anode) plus an alkaline electrolyte. Compared to other batteries, a silver oxide battery has a higher open circuit potential (1,55V). It also has a flatter discharge curve than a standard alkaline battery.
