Duracell Specialty 2025 lithium coin batteries are made for your specialty devices. They have up to 10 years of in-storage guarantee so you can be confident these lithium coin batteries will be ready when you need them. To help ensure the safety of your children and discourage swallowing, Duracell has developed the Baby Secure Technology, a bitter taste layer applied on the back side of the cell, and has designed a Baby Secure pack, child-resistant packaging with double blister so that it is impossible for a child to open without scissors. They are suitable for use in keyfobs, small remotes, scales, wearables, sensors, medical devices (glucometers, digital thermometers), sports devices (heart rate monitor, bike accessories).
