Button cell battery everActive CR2430 Lithium 3 V, 24.5 mm × 3 mm, pack of 5

The Everactive Single-use battery CR24305BL is a lithium coin cell designed to supply stable 3 V power to small electronic devices. With a thickness of 3 mm and a diameter of 24.5 mm, this pack contains five CR2430-size batteries suitable for consumer electronics that require a compact, long-lasting power source. The battery chemistry and form factor are intended to deliver consistent voltage over shelf life and use, making it suitable for low- to moderate-drain devices where replacement access may be occasional.

Advantages

These lithium CR2430 batteries offer a high energy density and low self-discharge rate, which supports long storage life and dependable performance in intermittent-use devices. Their compact coin-cell form provides a secure fit in CR2430-compatible compartments and maintains stable output at a nominal voltage of 3 V. The five-piece pack provides spare cells for multiple devices or future replacements.

Suitable for

• Key fobs and car remotes that use CR2430 size cells
• Small medical devices such as thermometers and glucose meters
• Watches and wearable electronics compatible with CR2430
• Calculators, small toys and electronic tools with coin cell compartments

How to use

Insert the battery into the device following the polarity markings: the positive (+) side typically faces outward or toward the spring contact depending on the device design. Ensure the compartment is clean and free of corrosion before inserting a new cell. Replace all batteries in multi-cell devices at the same time when recommended by the device manufacturer. Dispose of used lithium batteries according to local regulations and recycling guidelines.

Recommendations

Store batteries in a cool, dry place away from direct sunlight and metal objects. Avoid short-circuiting, disassembling, heating above recommended temperatures, or exposing batteries to fire. Keep out of reach of children and seek immediate medical attention if a battery is swallowed or inserted into the body.
