Looking for batteries that can handle demanding devices and extreme conditions? Energizer Ultimate Lithium CR2016 are the ideal choice for key fobs, remote controls, glucose meters, sports and heart rate monitors, games, toys, and keyless entry systems. Thanks to lithium technology, they provide reliable performance and long service life even at low or high temperatures.
Safety comes first. The new Color Alert technology temporarily turns the mouth blue upon contact with saliva to signal possible ingestion. The non-toxic bitter coating helps discourage putting the battery in the mouth, and the secure packaging requires scissors to open.
