Button cell battery Varta V3/80H-FLAT 80 mAh 3.6 V — lithium coin cell for electronics

Varta V3/80H-FLAT is a 3.6 V lithium button cell with a nominal capacity of 80 mAh, designed for compact electronic devices that require a flat coin cell format. The cell delivers a steady voltage profile and extended shelf life, making it suitable for backup power and low-drain applications where a compact, long-lasting power source is needed.

Advantages

The flat lithium chemistry offers stable nominal voltage and low self-discharge, ensuring reliable performance after storage. Its compact dimensions and flat design allow installation in tight battery compartments and shallow holders. The battery’s construction supports consistent low-current discharge, which is appropriate for memory backup and small electronic circuits that need uninterrupted power over long periods.

Suitable for

• Memory backup in electronics and embedded systems
• Alarm systems and security sensors
• Small sensors and IoT endpoint devices with low current draw
• Portable electronics, handheld instruments, and remote controls with flat battery compartments

Key specifications

• Chemistry: Lithium
• Nominal voltage: 3.6 V
• Nominal capacity: 80 mAh
• Cell type: Flat button/coin cell
• Designed for low to very low continuous discharge currents
• Long shelf life and low self-discharge rate

How to use

Install the battery in the device following the polarity markings, ensuring the correct orientation of the positive and negative terminals. Use appropriate battery holders or contacts that make firm, clean contact with the cell surfaces. Replace the cell before the device indicates low voltage or when functions dependent on backup power begin to fail. Store unused cells in a cool, dry place away from metal objects that could short the terminals.

Recommendations

Do not attempt to recharge the cell, puncture, crush, or expose it to fire or high temperatures. Dispose of spent cells according to local battery recycling regulations. For devices with occasional high-current pulses, verify device current draw compatibility with a 3.6 V lithium button cell to avoid reduced runtime.
