Button/coin lithium battery everActive CR2450, 3 V, 5 mm height — pack of 5

The everActive Single-use battery CR24505BL is a lithium coin cell sized CR2450 with a nominal voltage of 3 V. Supplied in a pack of five, each cell has a thickness of 5 mm and a diameter of 24.5 mm, providing compact, stable power for a range of small electronic devices. The design is intended for applications where a long shelf life and consistent output are required, while the single-use chemistry delivers reliable performance until end of service.

Advantages

The battery uses lithium chemistry to offer high energy density and low self-discharge, which helps preserve capacity during storage. Its compact CR2450 form factor fits devices that accept button/coin cells with a 24.5 mm diameter and 5 mm thickness. A nominal voltage of 3 V is compatible with many consumer electronics, and the five-cell pack provides spare units for replacements. The single-use construction makes the cells maintenance-free and ready to install.

Suitable for

• Wrist devices and small medical instruments designed for CR2450 cells
• Key fobs and security sensors
• Remote controls and small wireless peripherals
• Memory backup modules and real-time clocks in consumer devices
• Battery-powered calculators and LED indicators

How to use

Insert the cell into the device following the polarity markings (+ on the top) and the device manufacturer’s instructions. Ensure the battery compartment is clean and dry before installation. Replace only with the same type and size (CR2450) to maintain device performance. Dispose of spent lithium cells according to local regulations for household batteries and recycling programs.

Recommendations

Store unused cells in a cool, dry place away from direct sunlight and heat sources to reduce self-discharge. Do not attempt to recharge, open, or short-circuit the cells. Keep out of reach of children and follow local disposal rules for lithium batteries.
