The Duracell Specialty 2032 lithium coin batteries are produced with high-purity lithium and provide +70% extra life* (*compared to the IEC Service Output test minimum average duration for 2032 Lithium Coins. Actual performance may vary depending on the device and usage patterns) for your specialized devices. These batteries have a shelf life of up to 10 years, giving you confidence that they will be available when needed. To prevent children from swallowing these batteries, Duracell has developed Baby Secure Technology, which includes a bitter taste layer applied to the back of the cell. Duracell also created the Baby Secure pack, a tamper-proof pack with a double blister that is impossible for children to open without scissors. These batteries are compatible with a range of devices, including keyfobs, small remotes, scales, wearables, sensors, medical equipment such as glucometers and digital thermometers, and sports gear like heart rate monitors and bike accessories.
