Panasonic lithium coin batteries still have 90% of their original capacity even after 10 years. They are chemically very stable, due to the combination of lithium and manganese dioxide. At all operating temperatures under low-load discharge conditions, long-term discharge has been verified.
Ultra Compact Power
In an ultra compact design, the Panasonic lithium coin battery has a high voltage of 3V. That's why a single lithium battery can replace two, three or more conventional batteries. A powerful source of energy is also available for very small devices.
High Reliability and Safety
Repeated tests have been conducted by Panasonic tests on the various safety and performance characteristics of the Lithium Coin, plus the effects of environmental factors such as temperature. A wealth of corroborative data on the performance of the batteries has been accumulated that cannot be pinpointed by short-term accelerated tests. As a result, 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.
