Energizer Button Battery, 9.5mm Diameter, 1.55V Nominal Voltage - 7638900253078
This button battery is a low-drain silver oxide cell designed to supply 1.55V for small electronic devices such as timepieces and precision instruments. Manufactured to IEC 60086-3 standards, it operates across a practical temperature range and offers stable output suitable for applications requiring steady voltage over long standby periods.
Features and Benefits:
• 1.55V nominal voltage delivers consistent device operation
• 55mAh capacity supports extended low-current service
• Silver oxide chemistry ensures stable discharge profile
• Flat contact termination suits compact, low-profile assemblies
• Self-discharge under 5% per year preserves shelf life
• 55mAh capacity supports extended low-current service
• Silver oxide chemistry ensures stable discharge profile
• Flat contact termination suits compact, low-profile assemblies
• Self-discharge under 5% per year preserves shelf life
Applications
• Used with analogue and digital wristwatches requiring 1.55V
• Suitable for medical timing devices with low-drain demands
• Ideal for Compact measuring instruments needing stable voltage
• Can be used for small sensors and remote controls
• Appropriate for repair and replacement of SR48 SR54 batteries

What load and temperature produce the stated capacity?
Capacity is measured at a continuous discharge through an 18.2kΩ load at 20°C down to 1.2V.
How does the cell behave electrically under low drain?
The silver oxide chemistry provides a near-flat voltage during extended low-current discharge, supporting predictable device timing.
What is the expected annual self-discharge at typical storage conditions?
Self-discharge is specified as less than 5% per year when kept at 20°C.
What are the manufacturing and approval references for the cell?
The cell is produced to IEC 60086-3 standard.
