Panasonic VI-3TF2-SK9B CR2450 3V Lithium Battery

The Panasonic CR2450 is a 3-volt lithium primary coin cell battery engineered for devices that demand more capacity than standard CR2032 cells can provide. With a rated capacity of 620mAh, it delivers significantly more energy in a form factor that is only slightly larger in diameter, making it a common choice for automotive key fobs, medical monitoring equipment, digital thermometers, and other compact electronics. Panasonic's lithium chemistry ensures a continuous and stable voltage supply throughout the battery's life, so devices operate at full performance rather than gradually dimming or slowing as the cell drains.

Beyond raw capacity, the CR2450 offers practical advantages in storage and environmental resilience. Its long shelf life means you can buy spares and keep them ready without worrying about self-discharge, and its temperature resistance allows reliable operation in both heated indoor environments and cooler outdoor conditions. As a single-use primary cell it is not rechargeable, but for the low-drain, long-duration applications it is designed for, the combination of high energy density, stable output, and extended shelf life makes the Panasonic CR2450 a dependable choice.
