The Applied Technical Services Family of Companies’ (FoCs’) coin battery testing services ensure that coin batteries comply with regulatory requirements. All battery technologies have their inherent dangers, but small batteries, such as coin batteries, present unique risks to consumers. Our coin battery tests help ensure that our clients comply with Reese’s Law, protecting both themselves and consumers from the severe consequences that can accompany the accidental ingestion of coin batteries.
What is a Coin Battery?
Coin batteries are small batteries comprised of a single electrochemical cell. Known for their distinct coin shape, coin batteries are commonly used to power lower-power devices such as hearing aids, car key fobs, watches, and kitchen scales. They’re revered for their low discharge rate, extended shelf life, and stable voltage output. However, their minuscule size makes them a hazard to consumers, specifically young children, so all coin batteries and products containing coin batteries must comply with Reese’s Law if they are to be sold in the United States.
What is Reese’s Law?
Reese’s law is a federal law establishing stringent regulations regarding the packaging, performance, and labeling of products containing coin batteries. Passed in 2022, the law ushered in a new wave of regulations pertaining to a wide range of consumer products, including the following:
- TV remote controls
- Vehicle key fobs
- Smart watch
- Wireless doorbell
- Thermometers
- Home security systems
- Battery-powered candles
- Kitchen scales
The Consumer Product Safety Commission (CPSC) codified ANSI/UL 4200A in 2023, making it the standard that defines the parameters of Reese’s Law.
