Energizer Button Battery, 6.8mm Diameter, 1.55V Nominal Voltage - 7638900055108

This button battery is a low-profile silver oxide cell designed to deliver 1.55V for small continuous low-drain devices. It combines a Compact form with a flat contact termination and is intended for applications where consistent voltage and a lightweight energy source are required. The cell’s construction supports stable output across typical ambient conditions encountered in consumer and professional equipment.

Features and Benefits:

• Silver oxide chemistry provides stable voltage during discharge
• Nominal voltage of 1.55V supports precise electronic timing
• Typical capacity of 15mAh yields extended service at low drains
• Low internal impedance of 30-40Ω improves voltage under load
• Lightweight 0.28g reduces overall device mass
• Flat contact termination ensures secure surface connection

Applications

• Used with wrist instruments requiring thin cell profiles
• Suitable for Compact sensing devices with low current draw
• Ideal for replacement in small electronic timers and toys
• Can be used for precise calibration gadgets needing steady voltage
• Suitable for Compact medical monitoring accessories

What is the expected cut-off voltage under defined test conditions?

The load cut-off is specified at 1.2V for the capacity measurement.

How was the typical capacity determined?

Capacity was measured to 1.2V using a 94kΩ continuous drain at 21°C.

What is the cell’s impedance characteristic?

Impedance at 40Hz is given in the range 30-40Ω, affecting dynamic response.

How thin is the cell for tight assemblies?

The cell has a low profile with a height of 1.6mm.

What physical size and contact style are provided?

The cell has a diameter of 6.8mm and a flat contact termination.
