FAQs About CR2430 Batteries

Is a CR2430 battery the same as an CR2450?

Although the CR2450 and CR2430 batteries have the same diameter (24.5mm), they are different in height. The height of a CR2450 battery is 5.0 mm, while the height of a CR2430 battery is 3.0 mm.

Can I use a CR2450 battery as a replacement for a CR2430 battery?

Due to the height difference, a CR2450 battery is thicker than a CR2430 battery. This means that in some devices, using a CR2450 battery may cause the device to not work properly or damage the device. Therefore, it is not recommended to use a CR2450 battery in a device that requires a CR2430 battery. Unless the design of the device allows for a thicker battery, then that is a replacement!
