Button Cell and Coin Battery Product Safety
16 CFR part 1263; 15 U.S.C. § 2056e; ANSI/UL 4200A-2023 as incorporated
Reese’s Law and part 1263 address ingestion hazards from button cell and coin batteries in consumer products and packaging. Securing the compartment, resisting battery release during testing and communicating the hazard are separate obligations. Defined toy and battery exclusions must be assessed specifically. The federal incorporation of UL 4200A-2023 does not mean every battery product must purchase a private UL certification mark.
