Difference in Features
LR44 Features:
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 excellent leakage resistance.
