Energizer Button Battery, 1.55 V, 7.9 mm Diameter

This button battery provides a compact, low-profile power source for small electronic devices, delivering a nominal 1.55V from a silver oxide chemistry designed for continuous low-drain operation. It offers a slim profile suited to tight assemblies and is intended for applications where stable voltage and predictable discharge behaviour at typical room temperature are required.

• 9.5mAh capacity supports extended low-drain service
• Silver oxide chemistry yields stable voltage under light loads
• Low internal impedance 30-40ohm enhances Pulse performance
• Flat contact termination enables secure electrical connection
• Weight 0.24g minimises added mass in Compact devices

• Suitable for precision analogue watch movements
• Ideal for small medical monitoring instruments
• Used with wearable sensors requiring steady voltage
• Can be used for calculators and sensing modules
• Appropriate for remote controls with low continuous draw

The typical end-of-service cut-off is 1.2V under the specified test conditions.

Capacity is determined to 1.2V using a continuous 100Kohm drain at 21°C.

Performance figures were recorded at 21°C (70°F) to represent standard room conditions.

At the typical low-drain test the current is approximately 0.016mA delivering 1.55V initially.
