Coin cell battery RENATA 701977 3V Lithium (coin-type, 3 V)

RENATA 701977 is a 3V lithium coin cell battery designed for small electronic devices that require a compact, long-life power source. The coin-type form factor delivers stable voltage and a long shelf life typical of lithium chemistry, making it suitable for applications where consistent low-current power is needed and space is limited.

Advantages

The battery provides stable 3V output and low self-discharge, enabling extended storage and reliable operation in low-drain devices. Its compact coin shape allows easy replacement in tight housings, and lithium chemistry offers a longer shelf life compared with alkaline alternatives. The cell is intended for consistent performance across typical temperature ranges encountered in consumer and medical electronics.

Suitable for

• Wristwatches and chronometers
• Calculators and small electronic instruments
• Remote controls and key fobs
• Medical devices with low power consumption (e.g., glucometers, thermometers)
• Memory backup for electronic equipment

Key specifications

• Nominal voltage: 3 V
• Cell type: Lithium coin cell
• Form factor: Coin-type, compact diameter and slim profile
• Intended use: Low-drain devices and memory backup
• Storage characteristic: Low self-discharge for extended shelf life

How to use

Ensure the device is powered off or in a safe state before replacing the cell. Carefully open the battery compartment according to the device instructions, observe correct polarity when inserting the coin cell, and close the compartment securely. Dispose of the replaced battery according to local regulations for lithium batteries and avoid short-circuiting or exposing the cell to high temperatures.

Usage recommendations

Store unused batteries in a cool, dry place away from metal objects and direct heat. For devices that remain unused for long periods, remove the battery to prevent potential leakage and preserve both the device and the battery life.
