Energizer 357/303 Series Button Battery, 1.55V Nominal Voltage, 138mAh Capacity - 7638900252989

This button battery provides a Compact silver oxide power source for low-drain electronic devices, delivering a steady 1.55V output suitable for continuous and intermittent use. It is intended for applications requiring a small, lightweight cell with consistent voltage under light loads and predictable service behaviour across common ambient temperatures.

Features and Benefits:

• 138mAh capacity supports extended low-drain operation
• 1.55V nominal voltage maintains consistent device performance
• Low impedance of 2-8Ω ensures efficient Pulse response
• 6.8KΩ drain yields approximately 685 hours service time
• Flat contact termination simplifies installation in compartment holders

Applications

• Suitable for analogue and digital wrist instruments
• Ideal for portable calculators and small electronic toys
• Used with medical monitors requiring stable low-drain power
• Can be used for laser pointers and measurement tools

What is the typical current draw under standard test conditions?

Typical drain at 1.37V is 0.201mA when tested on a 6.8KΩ continuous load at 21°C.

How does temperature affect service performance?

Service varies with temperature, the datasheet shows reduced service at low temperatures and improved service at higher temperatures relative to 20°C.

What is the electrical cut-off criterion used for capacity rating?

Capacity is specified to 1.2V cut-off under the continuous 6.8KΩ discharge test at 21°C.

What are the cell construction components relevant to its operation?

The cell includes a gel anode, cathode layers, separator, gasket and metal can affecting internal resistance and sealing.
