Coin batteries don't make headlines all that often, but today shifts that trend with a smart new development. Energizer has released a new Ultimate Child Shield version of its 20mm coin lithium batteries. As the name implies, the tech is aimed at reducing the number of health risks if a child accidentally swallows the battery. These coin batteries don't cause burning in the esophagus if ingested, and they also contain a dye that will color a child's mouth blue if it comes in contact with saliva.
