The US Consumer Product Safety Commission (CPSC) voted to approve a mandatory standard to reduce button cell and coin battery ingestion hazards to children six years and younger. These batteries are used in many types of consumer products from keyless entry remotes and wireless game controllers.

Pursuant to Reese's Law, CPSC voted to adopt ANSI/UL 4200A-2023 Standard for Safety for Products Incorporating Button Batteries or Coin Cell Batteries, as the mandatory standard for consumer products containing button cell or coin batteries. The Commission also established labeling requirements for button cell or coin battery packaging.
