The Panasonic CR1220 Lithium Coin Cell is a powerful replacement battery typically used in calculators, heart rate monitors, remote starters and other small electronics. The pint-sized power source uses a sophisticated Lithium Manganese Dioxide chemistry, which not only provides the cell with the high voltage needed for high-performance devices, but has an extremely low self-discharge rate, giving it a lengthy shelf life.

Applications

For devices where traditional batteries cannot be used, Lithium Coin CR1220 has a proven track record. You can use the batteries for digital watches, laser pens, calculators, fitness appliances, car keys and medical devices like a tensiometer and a clinical thermometer.

Ultra-compact power

The Panasonic lithium coin CR1220 battery has a high voltage of 3V and an ultra-compact design: that means lots of power in one battery. So when you needed two, three or more traditional batteries, now you only need one lithium battery. Your small devices are by this provided with a powerful source of energy.

High reliability and safety

Repeated tests were conducted by Panasonic on the various performance and safety characteristics of the Lithium Coin CR1220 battery. Also the effects of environmental factors such as temperature were tested. A wealth of corroborative data on the performance of the Panasonic batteries has been accumulated and this cannot be pinpointed by short-term accelerated tests. The result is that Panasonic have won approval under the UL safety standards in the United States and wide recognition throughout the world for their high reliability and safety.

Very low self-discharge

Because the Panasonic lithium coin CR1220 batteries are chemically very stable, they still have 90% of their original capacity even after 10 years. The stability is the result of the combination of lithium and manganese dioxide. The long-lasting function of these batteries has been verified at all operating temperatures under low-load discharge conditions.
