Button cell battery Voltcraft ML 2032, 3 V, 65 mAh

Rechargeable button cell battery Voltcraft ML 2032 delivers a nominal voltage of 3 V and a rated capacity of 65 mAh in the standard 2032 form factor. It is designed to provide compact, stable power for small electronic devices that require a 3 V ML2032-type cell. The battery is suitable for use where a rechargeable alternative to disposable coin cells is preferred and fits into devices with space for a 20 mm diameter, 3.2 mm thick button cell.

Advantages

The Voltcraft ML 2032 offers rechargeability with consistent voltage output, reducing the need for frequent replacements. Its compact dimensions match the standard 2032 footprint, making it a direct fit for many watch, small electronics and sensor compartments. The battery's chemistry provides low self-discharge and reliable performance in applications with intermittent loads. Being rechargeable, it can lower long-term operating costs and environmental waste compared to single-use coin cells.

Suitable for

• Wristwatches and wearable timepieces requiring a 3 V coin cell
• Calculators and handheld electronic instruments
• Remote controls for small devices and key fobs
• Medical sensors and monitoring devices with compatible battery compartments
• Backup memory modules and real-time clock circuits in compact electronics

Key specifications

• Cell type: rechargeable button cell (ML chemistry)
• Nominal voltage: 3 V
• Rated capacity: 65 mAh
• Form factor: 2032 (20 mm diameter, approx. 3.2 mm thickness)
• Typical use: low-drain to moderate intermittent-load devices

How to use

Install the Voltcraft ML 2032 into the device's battery compartment observing correct polarity. Use a compatible charger specified for rechargeable ML-type coin cells and follow the charger's instructions for charging current and duration. Avoid charging in equipment not designed for rechargeable cells. When replacing an existing disposable coin cell with this rechargeable type, confirm that the device's contacts and space accept the 2032 form factor and that the device does not apply charging current to the cell during operation.

Usage recommendations

Store batteries in a cool, dry place and avoid exposure to high temperatures. Recharge according to the charger manufacturer's guidelines and do not dispose of the battery in fire. If the battery shows signs of damage or leakage, discontinue use and follow local regulations for battery disposal.
