Button cell battery Renata CR2025 3V lithium — 1 piece

Renata CR2025 3V lithium button cell — single piece — is a compact power source designed for small electronic devices that require a stable 3V supply. This coin cell delivers consistent voltage and long shelf life characteristic of lithium chemistry, making it suitable for periodic replacements and spare parts. The battery is supplied as one piece for easy substitution in devices that accept CR2025-size cells.

Advantages

The Renata CR2025 offers a steady 3V output and low self-discharge, providing reliable performance over extended storage and use. Its compact, standardized CR2025 form factor ensures wide compatibility with watches, key fobs, calculators and small electronics. The lithium composition yields a high energy density relative to alkaline alternatives, resulting in a longer operational life in low-to-moderate drain devices. The single-piece packaging makes it convenient to carry a spare for emergency replacement.

How to use

To replace a spent CR2025 cell, open the battery compartment of the device according to the manufacturer’s instructions, taking care to note polarity markings. Remove the old cell and insert the Renata CR2025 with the correct orientation, ensuring firm contact with the terminals. Close the compartment securely and verify device operation. Observe standard safety precautions: avoid short-circuiting the terminals, do not attempt to recharge, and keep out of reach of children.

Usage recommendations

Store unused cells in a cool, dry place away from metal objects. Dispose of used lithium button cells according to local battery recycling regulations. Replace batteries in matched sets when devices use multiple coin cells, and use the correct CR2025 size to ensure proper fit and electrical contact.
