Coin cell battery Voltcraft CR2450 Lithium 3V 580mAh

Voltcraft CR2450 Lithium 3V 580mAh is a compact coin cell battery designed to deliver steady power for low-drain and intermittent-load electronics. With a nominal voltage of 3V and a capacity of 580mAh, this battery is suitable as a primary or replacement power source for small devices that require long shelf life and reliable voltage stability. The cell’s construction provides consistent output over extended periods and is optimized for devices where size and longevity are critical.

Advantages

The battery offers a high energy density in a small form factor, ensuring extended operating time compared with standard button cells of lower capacity. Its low self-discharge rate supports long storage life, and the stable 3V output helps maintain consistent device performance. The coin cell is designed for straightforward installation and reliable operation in a range of low-power electronics.

Suitable for

• Watches and wearable devices
• Calculators and small office electronics
• Key fobs and remote controls
• Medical devices with low power requirements (non-implantable)
• Memory backup and CMOS batteries for electronics

Key specifications

• Chemistry: Lithium
• Nominal voltage: 3 V
• Nominal capacity: 580 mAh
• Cell type: Coin / button
• Typical operating temperature range: suitable for common room-temperature applications
• Suitable for low-drain and intermittent-load devices

How to use

Insert the coin cell into the device’s battery compartment observing polarity markings: the positive (+) terminal typically faces outward or up depending on device design. Ensure the contact surfaces are clean and free of corrosion before installation. For devices with a battery holder or clip, press the cell into place until it seats securely. Replace the battery when device performance declines or when the device indicates low battery, and dispose of the used cell according to local regulations for lithium batteries.

Usage recommendations

Store unused batteries in a cool, dry place away from metallic objects and heat sources. Avoid short-circuiting the terminals and do not attempt to recharge single-use lithium coin cells. Keep out of reach of children and follow local disposal guidelines to minimise environmental impact.
