Duracell CR2025 lithium coin batteries, 3 V, 2-pack

Two Duracell CR2025 lithium coin cells rated at 3 V in one blister pack, so the second one stays as a spare. Duracell lists cycling computers, postal scales, clock radios, electronic organisers, blood glucose meters, heart rate monitors and pedometers.

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