Duracell Specialty 2025 lithium coin batteries are manufactured using high-purity lithium, providing +50% extra life* (*compared to the IEC standard test minimum average duration for 2025 Lithium Coins. Actual performance may vary depending on the device and usage patterns) for your specialized devices. With a shelf life of up to 10 years, these lithium coin batteries are sure to be available when you need them. Duracell also prioritizes the safety of children and discourages battery ingestion by incorporating a bitter taste layer, known as Baby Secure Technology, on the back of the cell. Furthermore, Duracell has designed a tamper-proof pack with double blister, called the Baby Secure pack, that can only be opened with scissors and cannot be accessed by children. These batteries are appropriate for use in a variety 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.
