Duracell Specialty 2016 lithium coin batteries are crafted using high-purity lithium to provide +50% extra life* (*compared to the IEC standard test minimum average duration for 2016 Lithium Coins. Actual performance may vary depending on the device and usage patterns) for your specialized devices. With up to 10 years of guaranteed shelf life, you can be confident that these lithium coin batteries will be available when you need them. Duracell also ensures the safety of your children and discourages them from swallowing the batteries by applying a bitter taste layer known as Baby Secure Technology on the backside of the cell. Additionally, the company has created a Baby Secure pack, which is a tamper-proof pack with double blister that cannot be opened by children without scissors. These batteries are appropriate for use in a variety of devices, including keyfobs, small remotes, scales, wearables, sensors, medical devices such as glucometers and digital thermometers, and sports devices like heart rate monitors and bike accessories.
