The 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 longer shelf life. 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. 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. Features: Can be used in a wide range of temperatures (-30°C to 60°C) High voltage (3V) Self-discharge is very low; long shelf life of up to 10 years A full lineup for use in a wide variety of applications No mercury added The very high weight-to-power ratio High leak protection
