Lithium coin batteries are lightweight and high energy density batteries for a variety of applications and are used in many long-life, critical devices, such as artificial pacemakers and other implantable electronic medical devices. Also those batteries are in use in toys, keyless car entry systems, cameras, watches and clocks. Lithium cells are thin compared to their diameter.
Voltage characteristic of Sony lithium coin batteries remains stable for a long period of discharge. That improves the reliability of equipment that uses the lithium battery.
Sony's lithium batteries provide superb characteristics over a wide temperature range of -30 to +70 C°. The Sony's battery construction and electrolyte ensure superb leakage resistance over a long span of time.
Sony's innovative technology minimizes battery self-discharge. The annual self-discharge rate at room temperature is approximately 1% of the nominal capacity.
