Duracell DL2025 / CR2025 lithium coin batteries are ideal for use in key fobs, car key remotes, sensors, medical and sports devices. They offer up to 70% extra life compared to the minimum average duration of the Electronic Key IEC standard test for 2025 lithium coin batteries.

In partnership with the European Association of Paediatrics, this is Duracell’s most secure battery ever. It features a non-toxic bitter taste ring-shaped layer with Bitrex, applied to the back side of the cell to discourage swallowing by babies and toddlers. It also comes in baby-secure packaging – a double blister that’s difficult to open without scissors.
