Pilha botão Varta V3/80H 80 mAh 3,6 V Lítio

Varta V3/80H is a button cell lithium battery with a nominal voltage of 3.6 V and a capacity of 80 mAh. It is designed for small electronic devices that require a compact power source with consistent output and long shelf life. The cell delivers stable voltage suitable for intermittent or continuous operation in low-drain and moderate-drain applications, and is compatible with devices that accept the V3/80H form factor.

Advantages

The battery offers a compact round form factor and a high energy density relative to its size, enabling extended operation in miniature electronics. Low self-discharge ensures reliable storage life, while the lithium chemistry provides stable voltage over most of the discharge curve. The cell is suitable for temperature ranges typical for consumer and professional electronics and maintains performance in devices requiring occasional infrequent power bursts or steady low-current draw.

Suitable for

• Watches and timekeeping devices
• Memory backup modules for small electronics
• Wireless sensors and remote transmitters
• Portable medical instruments with compact battery compartments
• Industrial instruments and measurement devices with low to moderate power demands

Key specifications

• Chemistry: Lithium
• Nominal voltage: 3.6 V
• Nominal capacity: 80 mAh
• Form factor: button cell / coin cell
• Typical use: low-drain and moderate-drain miniature devices

How to use

Install the battery in the device following the manufacturer’s polarity markings and enclosure instructions. Ensure the battery is seated correctly in the compartment and that contact surfaces are clean and free of corrosion. Replace with the same type and voltage to preserve device functionality and avoid damage. Dispose of used cells according to local regulations for lithium batteries and do not attempt to recharge primary lithium cells.

Recommendations

Store unused batteries in a cool, dry place away from direct heat and metal objects. Avoid mixing new and used cells or different battery chemistries in the same device. For devices that are infrequently used, remove the battery if long-term storage of the device is planned to prevent potential leakage or contact degradation.
