Feature

• Lightweight, High Voltage and High Energy Density
  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.
  - Standard / High drain: -30 to +70 degrees C
  - Extended temperature: -40 to +85 degrees C
  - Heat-resistant: -40 to +125 degrees C
  
  
• 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.
• UL Approved Parts
  Murata's Coin Manganese Dioxide Lithium Batteries are approved by UL.
  (UL1642 File No. MH12566)
• RoHS directive・European Directives
  This product does not contain Mercury (Hg), Cadmium (Cd), nor Lead (Pb), and conforms to EC regulation values (Directive 2006/66/EC, 2013/56/EU).
  Battery pack are excluded from RoHS directive (DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment).
