Energizer Button Battery, 1.55V Nominal Voltage, 34mAh Capacity - 7638900252972

This button battery provides a Compact silver oxide power source for low-drain devices, delivering a stable 1.55V nominal voltage and formulated for continuous, low-current operation. It is designed for small electronics where consistent voltage and minimal size are required, functioning reliably across normal ambient temperatures.

Features and Benefits:

• 34mAh capacity supports extended low-drain operation
• 1.55V nominal voltage preserves device voltage stability
• Silver oxide chemistry offers stable output under light loads
• Low impedance of 15-30ohm improves Pulse response
• 0.5g mass minimises weight impact in miniature devices

Applications

• Suitable for wristwatch power requirements
• Used with small medical monitoring devices
• Ideal for calculators and handheld instruments
• Can be used for small sensors and measurement tools

What continuous drain was used to determine capacity?

Capacity was measured at a continuous 33Kohm drain and specified to 1.2V.

How is end-of-life voltage defined for this cell?

The load cut-off for service is set at 1.2V.

What impedance should designers expect at audio-frequency testing?

Impedance at 40Hz ranges between 15ohm and 30ohm.

How long does the cell run under the test drain at 21°C?

At 33Kohm continuous drain the documented run time is approximately 718 hours.
