In the United States, on average, over 3,000 pediatric ingestions of button batteries are reported annually. The proportion of major and fatal outcomes is increasing. Coin cells of diameter 20 mm or greater cause the most serious injuries, even if expended and intact. In Auckland, New Zealand as of 2018 there are about 20 cases per year requiring hospitalization.
