Duracell CR2450 lithium coin battery, 3 V

The Duracell CR2450 is a large 3 V lithium coin cell. Duracell lists cycling computers, postal scales, clock radios, blood glucose meters, heart rate monitors and lights. Check the code against the old battery before ordering, as a CR2450 does not replace smaller sizes.

The maker highlights: Duralock Power Preserve keeps an unused battery charged for up to 10 years, and the packaging is child-resistant.
