Overview
- Energizer, which launched the Ultimate Child Shield line Wednesday, is selling 20 mm cells in 2032, 2025, and 2016 sizes used in remotes, wearables, and trackers like Apple’s AirTag.
- The company says a proprietary titanium alloy stops the electrical current that forms on contact with saliva, which is what causes alkaline burns when a battery sticks in the esophagus.
- The batteries add deterrents that include child‑resistant packaging, a bitter coating to prompt spitting, and a food‑grade dye that turns the mouth blue within seconds.
- Doctors warn the cells can still choke or block the airway or gut, and they cite more than 3,500 U.S. ingestions each year, so prevention and fast medical care remain critical.
- Energizer cites independent testing but has not disclosed technical details, and ABC News reports it has not independently verified the company’s safety claims.
