All around you, Panasonic Coin Lithium batteries are providing safe power in devices we all depend on for life. High energy density and high 3 V output voltage support the trend towards device miniaturization. In fact, a single Coin Lithium can sometimes replace two or three conventional coin batteries. Use of organic electrolytes with a solidifying point lower than other battery types makes Coin Lithium ideal for use in wide range of temperatures. Backed by 90 years’ leading technical expertise, Panasonic Coin Lithium has evolved to become the world’s trusted micro-battery for safe, long-lasting power in diverse applications, from household electronics to the IoT devices that energize smart society.

Double Child Guard
Double Child Guard enhances protection against accidental battery ingestion by infants and young children. In addition to child resistant packaging, the coin lithium battery is coated with denatonium benzoate, an intensely bitter substance that activates the tongue’s type II taste cells, sending an aversive signal to the brain and triggering a reflex to expel the battery. Together, these innovative safety measures help reduce the risk of accidental battery ingestion.
Note: The bitter coating is applied to CR2016E, CR2025E, and CR2032E Coin Lithium batteries.

Bitter Coating
A bitter substance is applied to the battery’s negative terminal to deter accidental ingestion by infants and young children. The bittering agent, denatonium benzoate, is one of the world’s bitterest substances and is widely used in products designed to discourage ingestion. Developed under the guidance of pediatric experts, the coating application was optimized through verification testing involving infants and young children to determine the amount required to effectively deter accidental ingestion.

The Secret Behind the Structure
Coin Lithium has a unique case design that contributes to its amazing endurance. Concave cathode case and dimpled anode surface increase material adhesion, limit a rise in internal resistance, and support stable voltage and efficient discharge for lasting power.
