  • Excellent cost performance
    High cost performance has been achieved owing to the use of manganese dioxide as a cathode material.
  • Excellent stable discharge and high-drain pulse discharge characteristics
    Stable voltage output is available during the high-drain pulse discharge.
  • Excellent leakage resistance
    Murata-unique sealing structure, coupled with special sealing- material treatment, has helped accomplish the excellent leakage resistance.
