Overview
- Energizer introduced its Ultimate Child Shield line on Wednesday, with 2032, 2025, and 2016 coin cells now on sale in the U.S.
- Energizer says a proprietary titanium‑alloy design stops the electrical reaction that burns the esophagus, though it has not shared technical details.
- The batteries add a bitter coating, a saliva‑activated blue dye to flag ingestion, and child‑resistant packaging.
- Doctors warn the cells can still cause choking or a blockage, and they note more than 3,500 U.S. ingestions a year as a reason to seek immediate care.
- Apple has warned bitter‑coated cells may not work in AirTags depending on coating alignment, raising questions about device compatibility.
