Murata Button Battery, 3 V, 20 mm Diameter

The battery voltage is 3V, almost double that of normal alkaline or manganese batteries. This means that the number of batteries required for equipment can be halved for maximum space saving and weight reduction

Excellent Discharge Characteristics

Voltage characteristics remain stable even for a long period of discharge, greatly improving the reliability of equipment that uses the battery. Such equipment is also maintenance-free (battery replacement is seldom required)

Outstanding Temperature Characteristics

Murata's original organic electrolyte provides superb characteristics over a wide range of temperature from low to high

-40 to +85 degrees C (Extended temperature) -40 to +125 degrees C (Heat-resistant)

Excellent Leakage Resistance

The newly developed battery construction and electrolyte ensure maximum leakage resistance over a long span of time

Excellent Long-Term Reliability

Carefully selected active materials are used for the active material as well as for the electrolyte. These materials are sealed by Murata's innovative technology to minimize battery self-discharge. The annual self-discharge rate at room temperature and normal humidity is less than 1% of the nominal capacity
