Energizer Button Battery, 7.9mm Diameter, 1.55V Nominal Voltage - 7638900052909


This button battery is a low-profile silver oxide cell designed to deliver stable 1.55V power for small electronic devices that require continuous low-drain operation. It is intended for applications where compact, lightweight energy sources are necessary and provides consistent voltage under typical ambient conditions.

Features and Benefits:


• 39mAh capacity for extended low-current operation
• 55-65Ω impedance at 40Hz for predictable discharge behaviour
• 1.2V load cut-off supporting defined end-of-service point
• 0.58g mass minimises added weight in miniature devices
• Continuous drain tested on 22KΩ at 21°C demonstrating practical performance

Applications


• Suitable for wristwatches requiring silver oxide chemistry
• Used with small medical instruments needing steady low drain
• Ideal for Compact measuring instruments and sensors
• Can be used for key fobs and small remote controls
• Replacement 7.9mm button cell for precision timing devices

What is the typical test condition used to determine capacity?


Capacity is measured to 1.2V using a continuous 22KΩ load at 21°C.

How does temperature affect operating service?


Service varies with temperature, discharge performance declines at lower temperatures and increases at higher temperatures relative to 21°C.

What is the electrical behaviour during typical use?


The cell shows a near-constant 1.55V nominal voltage with gradual decline towards a 1.2V cut-off under continuous low-drain conditions.

What construction details influence internal resistance?


The combination of gel anode, cathode mix and separator yields an impedance in the 55-65Ω range at 40Hz.

How much internal volume does the cell occupy?


The typical volume is approximately 0.15cm3.
