ANSI/UL 4200A and Reese's Law: button and coin cell batteries

Reese's Law required CPSC to set a mandatory standard for consumer products containing button or coin batteries; CPSC's rule draws on ANSI/UL 4200A with modifications, covering battery compartment security, performance tests and warnings, plus packaging warnings.

What it covers

Choosing tests

Identify whether the product contains or is intended for button/coin batteries; test compartment security and warnings; issue a GCC (or CPC for children's products).
