Energizer Button Battery, 11.6mm Diameter, 1.55V Nominal Voltage - 7638900253047

This button battery provides a compact, low-drain power source for small electronic devices, operating at a nominal 1.55V and utilising a silver oxide chemical system. It is intended for continuous low-current applications at normal ambient temperatures and offers predictable discharge behaviour to maintain device function over extended service periods.

Features and Benefits:

• 84mAh typical capacity for extended operational time
• 1.55V nominal voltage for stable low-voltage supply
• Impedance 10-25ohm to support steady current delivery
• Flat contact termination for secure electrical connection
• Typical weight 1.35g enabling lightweight device designs

Applications

• Used with wristwatches requiring Compact coin cell power
• Suitable for small medical devices needing steady output
• Ideal for calculators and continuous low-drain instruments
• Can be used for key fobs and small remote controls

What is the expected end-of-discharge voltage for common loads?

The typical cut-off used for capacity measurement is 1.2V under the specified test conditions.

How was the 84mAh capacity determined?

Capacity was measured to 1.2V using a continuous 15kΩ drain at 21°C.

How does temperature affect service life?

Service varies with temperature, higher temperatures reduce available service percentage while lower temperatures generally preserve percentage service over time.

What internal construction elements support performance?

The cell comprises a gel anode, separator, gasket, can and cathode configured for silver oxide chemistry to maintain consistent output.

What electrical behaviour should be expected at low discharge rates?

At very low drains the cell shows prolonged service hours with gradual voltage decline as indicated by the typical discharge characteristics.
