Westinghouse CR2450 3 V lithium coin cells 5-pack

Reliable coin-cell power

This 5-pack of Westinghouse CR2450 lithium coin cells delivers 3 V output for compact electronic devices. Each cell measures 24.5 mm by 5 mm and is supplied on a card for easy storage. The chemistry provides stable voltage across the discharge curve. Suitable for owners of key fobs, medical sensors, calculators and similar low-drain equipment.

Simple drop-in replacement

The batteries fit any holder designed for the CR2450 form factor, including equivalents such as BR2450, ECR2450, KCR2450, LM2450 and 5029LC. No soldering or adapters are required; the card packaging keeps spares organised until needed. This frees up drawer space compared to loose cells and ensures the correct orientation is obvious. Builders who need a rechargeable format or a different diameter cannot use this pack.

Consistent output over time

Lithium chemistry maintains a steady voltage during extended use rather than dropping sharply after an initial burst. The manufacturer rates shelf life at up to 10 years, so cells retain usable capacity after long storage. Temperature resistance supports reliable operation in environments that see seasonal variation. Devices that demand high peak currents or rapid recharge cycles are not served by this chemistry.
