Detailed overview: Duracell CR2016 lithium 3V coin cell
The CR2016 battery is a 3-volt lithium coin cell. Within the family of 20 mm diameter round cells, it is the thinnest: it measures only 1.6 mm thick, versus 2.5 mm for the CR2025 and 3.2 mm for the CR2032. This slimness suits the flattest holders.
You find it in many devices: car keys and remotes, watches, gate remotes, calculators, electronic boards, bathroom scales and small gadgets. Its lithium chemistry ensures a stable 3V voltage and good life, including occasional use over several years.
This battery is sold here in a pack of 4, in its original Duracell packaging. It matches the reference DL2016. Duracell adds child-safety technology: a bitter-taste (Bitrex) coating and a hard-to-open pack, designed to limit the ingestion risk by young children, since swallowed coin cells are dangerous.
Be careful not to confuse CR2016, CR2025 and CR2032: they share the same diameter but have different thicknesses and capacities, and are not always interchangeable depending on the holder. Like all lithium coin cells, the CR2016 is single-use and recycles at end of life in battery bins. Handy to keep in reserve, the Duracell CR2016 is the ideal spare battery for flat devices.
