Description

The Duracell CR2450 is a 3V lithium coin cell battery measuring 24mm diameter by 5.0mm height, packaged as a single unit. Built with high-purity lithium chemistry, the CR2450 delivers stable voltage output across its discharge cycle and carries a 10-year in-storage guarantee backed by Duracell's Duralock Power Preserve technology, which minimises self-discharge when the battery is not in use.

CR2450 cells power car key fobs, remote controls, small medical devices such as glucose monitors, fitness trackers, bathroom scales, bike computers, and some watch models requiring higher capacity than CR2032 or CR2025 alternatives. The 5.0mm thickness makes the CR2450 one of the thicker coin cells in the CR range, offering approximately 620mAh capacity compared to the 240mAh of a CR2032, which extends runtime in devices with moderate continuous draw or occasional high-drain pulses such as key fob transmitters.

The lithium chemistry operates across a temperature range of -20°C to +60°C, making the CR2450 suitable for outdoor devices and car-based applications where temperature fluctuations occur. The single-pack format reduces packaging waste for users replacing one battery at a time and avoids the cost of multi-packs when only one cell is needed. The battery carries child-resistant blister packaging with 'Baby Secure Pack' design, meeting IEC 62115 safety requirements.

Frequently Asked

What devices use CR2450 batteries?

Car key fobs, remote controls, bathroom scales, glucose monitors, fitness trackers, bike computers, some watches, and small medical devices. The CR2450's higher capacity (approximately 620mAh) suits devices with moderate continuous draw or intermittent high-drain pulses.

How long does a CR2450 last in storage?

Duracell guarantees 10 years of shelf life when stored in the original packaging. Duralock Power Preserve technology minimises self-discharge, so batteries remain ready for use after extended storage.

Can a CR2450 replace a CR2032?

No. The CR2450 is 5.0mm thick, while a CR2032 is 3.2mm thick. Although both are 24mm in diameter and provide 3V, the CR2450 will not fit battery compartments designed for CR2032 cells due to the thickness difference.

What temperature range does it tolerate?

Lithium coin cells operate across -20°C to +60°C, making the CR2450 suitable for car key fobs left in vehicles during winter or outdoor devices exposed to temperature fluctuations.
