What Reese's Law is
CPSC says Reese's Law, Public Law 117-171, is carried out through 16 CFR part 1263, which sets performance and labeling requirements for consumer products containing button cell or coin batteries. Part 1263 says it is "intended to eliminate or adequately reduce the risk of injury and death to children 6 years old and younger from ingesting these batteries."
What it calls for
CPSC says battery compartments containing replaceable button cell or coin batteries must require a tool or at least two independent and simultaneous hand movements to open. CPSC describes warnings on the packaging, on the product, and in the instructions.
How toys fit in
CPSC says toys that comply with the battery requirements of 16 CFR part 1250 are exempt from part 1263, and that ASTM F963 section 4.25 covers battery-operated toys.
Keep batteries away
CPSC says to keep button or coin batteries away from young children. That includes spare and used batteries.
If a battery may have been swallowed

FAQ
General information only, for adults choosing toys for children. We do not test, certify, or rate any product, and we do not say any toy or kit is safe or right for a particular child or age. Before you buy or use one, read the maker's age grade, warnings, and instructions, follow any adult supervision directions, and check for recalls at cpsc.gov/Recalls. Keep small parts, magnets, button and coin batteries, and kit chemicals away from young children. A swallowed magnet, button battery, or coin battery needs medical help right away; do not delay. If you think a child swallowed or touched something harmful, call Poison Help at 1-800-222-1222. In an emergency, call 911.
