Energizer CR2016 Ultimate Lithium Coin Battery 3-In-1 Child Shield 2 pack

Featuring the world’s first 3-in-1 Child Shield with three lines of defense: colour alert, a bitter coating, and secure packaging. Colour alert technology dyes the mouth blue seconds after contact with saliva to indicate possible ingestion. Non-toxic bitter coating helps discourage ingestion, while the secure packaging is almost impossible to open without scissors. Ideal for use as remote batteries and medical device batteries; also an ideal power source for your keyless entry system, toys and games. Our longest lasting 2016 coin cell batteries last up to 12 years in storage to provide reliable power when you need it most.
