Coin cell battery everActive CR2450 3V lithium for small electronics and memory backup

everActive CR2450 is a 3V lithium coin cell battery designed for compact electronic devices and memory backup applications. The CR2450 format combines a slim profile with stable voltage output, providing reliable power for low-drain and intermittent-use devices such as watches, calculators, key fobs, small sensors and motherboard memory retention. The construction offers long shelf life and consistent discharge characteristics suitable for devices that require steady 3V supply in a compact form factor.

Advantages

The battery delivers a stable 3V output and low self-discharge for extended storage life. Its coin cell size provides a high energy density for the format, enabling long operating time in low-drain electronics. The construction is designed to maintain consistent voltage under typical small-load conditions and to fit standard CR2450 compartments and holders. The chemistry ensures reliable performance at room temperature and predictable behavior during intermittent use.

Suitable for

• Wristwatches and small timepieces
• Calculators and portable electronic meters
• Key fobs and car remote controls
• Small sensors, remote controls and LED indicators
• Memory backup for motherboards, alarm systems and other electronics

Key specifications

• Nominal voltage: 3V
• Cell type: lithium manganese dioxide (coin cell)
• Form factor: CR2450 (flat disc coin cell)
• Typical use: low-drain and intermittent-load devices
• Storage behavior: low self-discharge for long shelf life

How to use

Install the battery with correct polarity as indicated in the device battery compartment, ensuring the positive (+) side faces the appropriate terminal. Use a non-metallic or insulated tool if necessary to avoid shorting. Verify the device manufacturer’s compatibility with the CR2450 form factor before replacing the cell. Dispose of the depleted battery in accordance with local regulations for lithium batteries and do not incinerate or expose to high temperatures.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and metal objects. Replace batteries in complete sets where devices require multiple cells, and avoid mixing new and used batteries or different chemistries to preserve device performance and safety.
