U.S. Navy Seaman Jason De Castro and U.S. Air Force Staff Sgt. Benjamin Bugenig show the importance of proper battery disposal at Misawa Air Base, Japan, April 1, 2026. Proper disposal of batteries is important not only to service members but to anyone who uses disposable batteries, because all disposable batteries run the risk of fire or combustion due to improper discarding.
