Button Cell Battery Testing and Certification

Button cell batteries, also known as button batteries, are batteries shaped like a small button, typically characterized by a larger diameter and thinner thickness (compared to cylindrical batteries such as AA). Button cell batteries are categorized by shape, alongside cylindrical, square, and irregular-shaped batteries.

Button cell batteries are commonly available in rechargeable and non-rechargeable types. Rechargeable versions include 3.6V lithium-ion button cells (LIR series) and 3V lithium-ion button cells (ML or VL series). Non-rechargeable options include 3V lithium-manganese button cells (CR series) and 1.5V alkaline zinc-manganese button cells (LR and SR series).

According to new U.S. regulations, button cell batteries must undergo UL 4200a:2023 testing and bear a label. Common button cell types include AG3, AG10, and AG13 used in toys and gifts, CR2032 used in computer motherboards, CR2025 used in electronic dictionaries, and CR2016 or SR44, SR626 used in electronic watches.
