Our environmental awareness led us again and again to innovating ideas reducing the use of materials that can harm the environment. However, the long life (twice the capacity of an alkaline button cell) and stability of SR44 make it a great choice. The use of silver results in a higher price compared with other button cells or coin type batteries. Superior silverĪ large capacity and a continuous high power supply till the end of its life cycle distingue the Panasonic SR44. Other devices include laser pens, calculators and digital clocks. You can use them in digital watches, bike computers, heart rate monitors for athletes: typical applications where a stable operating voltage and a high-energy density are required. Panasonic SILVER OXIDE SR44 is perfect for precision electronic devices. Panasonic launched the production of Silver Oxide batteries in Japan back in 1976. It also has a flatter discharge curve than a standard alkaline battery. Compared to other batteries, a silver oxide battery has a higher open circuit potential (1,55V). Like all our batteries in this range, SR44 uses silver oxide as the cathode or positive electrode, zinc as the anode or negative electrode and an alkaline electrolyte.

Flat discharge curve for stable power until the end of the battery life.

Small battery with a high energy density, suitable for small devices.

Very reliable performance for precision electronics.

These batteries are perfect for use in watches, medical devices, calculators and keyfobs. Panasonic silver oxide SR44 batteries offer high performance in a wide variety of appliances.
