Silver Oxide - SR721

Suitable for small high drain appliances

SR721 benefits

• Small battery with a high energy density, suitable for small devices
• Flat discharge curve for stable power until the end of the battery life
• Very reliable performance for precision electronics
• Wide range available
• No mercury added
• Low self-discharge

Exceptional silver

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 SR721 make it nevertheless an excellent choice. Until the end of its life cycle, the Panasonic SR721 battery will have a large capacity and a continuous high power supply.

Appliances

Appliances in which you can use the Panasonic SILVER OXIDE SR721 include precision electronic devices such as digital watches, bike computers, heart rate monitors for athletes, and laser pens, calculators and digital clocks. etc. They are particularly adequate for appliances where a stable operating voltage and a high-energy density are required.

Continuous power thanks to reliable technology

Silver oxide as the positive electrode (cathode), zinc as the negative electrode (anode) plus an alkaline electrolyte are the elements of which the SR721 is composed, just like all our batteries in this range. A silver oxide battery has a higher open circuit potential (1,55V) and a flatter discharge curve than a standard alkaline battery, compared to other batteries. Did you know that the production of Silver Oxide batteries was launched by Panasonic back in 1976?

Without added mercury

As a result of our environmental awareness, we could again and again work on innovating ideas reducing the use of materials that can harm the environment. This is also why the SR721 Silver Oxide battery today has 0% mercury added.
