Lithium button cell Energizer CR2025 3V - pack of 2

The Energizer CR2025 3V lithium button cell supplied in a pack of two is a compact power source for a variety of small electronic devices. Its nominal voltage of 3 volts and standard CR2025 size provide stable power for timekeeping, remote control functions and low-to-moderate drain electronics. The cell’s chemistry and design support a long shelf life and predictable discharge behavior, making it suitable for replacement in devices that require a non-rechargeable coin battery in the CR2025 format.

Advantages

The lithium chemistry delivers a consistent 3V output and a low self-discharge rate, extending usable life when stored. The CR2025 format is widely compatible with watches, key fobs, calculators and many small electronic devices, simplifying replacement. Supplied as a pack of two, this product ensures an immediate spare cell is available. The cells are designed to provide reliable voltage under typical operating conditions for products intended to use CR2025 batteries.

Suitable for

• Wristwatches and wearable timepieces
• Car key remotes and garage door remotes
• Calculators and small handheld electronic devices
• Medical devices such as glucometers and thermometers that specify CR2025
• Electronic toys, fitness trackers and small sensors

How to use

Before installation, confirm the device manufacturer’s recommended battery type and polarity. Open the battery compartment according to the device instructions, remove the exhausted cell and insert the new CR2025 with the correct orientation, ensuring firm contact with the terminals. After replacement, close the compartment securely and verify device operation. Dispose of used lithium cells according to local regulations for battery recycling or hazardous waste.

Usage recommendations

Store unused cells in a cool, dry place away from direct sunlight and metal objects to avoid short-circuiting. Avoid mixing new and used batteries or different chemistries in a single device. Keep batteries out of reach of children and seek immediate medical attention if a battery is swallowed.
