Power: ultra compact

Two, three or more conventional batteries can be replaces by a single lithium battery. That's because there's a lot of power in this ultra-compact design: 3V. Thanks to the Panasonic lithium coin CR1220 battery, even very small devices can now be provided with a powerful source of energy.

Self-discharge: very low

90% of their original capacity, that's how much power the Panasonic lithium coin CR1220 batteries still have after 10 years. Their chemical stability, which is due to the combination of lithium and manganese dioxide, is very high. Long-term discharge has been verified at all operating temperatures under low-load discharge conditions.

Reliability and safety: very high

Panasonic batteries have won approval under the UL safety standards in the United States and wide recognition throughout the world for their high reliability and safety. This is the result of repeated tests on the various safety and performance characteristics of the Lithium Coin CR1220, plus the effects of environmental factors such as temperature that Panasonic has conducted. We have accumulated a wealth of corroborative data on the performance of our batteries that cannot be pinpointed by short-term accelerated tests.


You can use these batteries in calculators, digital watches, memory back-up, laser pens, car keys, fitness appliances and medical devices like a clinical thermometer and a tensiometer. Lithium Coin CR1220 has a proven track record for appliances where conventional batteries cannot be used.
