CR2032 Batteries

CR2032 batteries form part of a broader category of specialised battery types, which are often referred to collectively as coin cells or button batteries. This is due to their distinctive shape and profile, typically consisting of a slim circular housing with two flat faces anywhere from 5mm-25mm in diameter, and an overall cylinder height of between 1mm-6mm. Thinner models tend to be referred to as coin batteries, while thicker versions might more commonly be described as button cells.

What does CR2032 mean?

The CR2032 battery type is an especially popular button-type cell, designed for use in a wide range of smaller, portable or handheld electronic devices and hardware.

In size terms, it falls somewhere in the middle of the coin/button battery range: as the number 2032 in the name denotes, it’s a 20mm diameter cell, with a height of 3.2mm.

The ‘C’ in CR2032 refers to the battery’s chemistry type - namely lithium - while the ‘R’ denotes the shape of the battery (round).

CR2032 battery uses

CR2032 batteries are among the most widely used of all coin/button cells, and are particularly associated with hardware such as computer motherboards, electronic scales, remote controls, key fobs and calculators. Similar-sized coin batteries can also be used to power various sorts of medical devices, including hearing aids and pacemakers.

Among the general characteristics of a lithium button battery such as a CR2032 are:

  • Better corrosion and leakage resistance than alkaline batteries
  • Rated at 3V, like all lithium coin cells (as opposed to silver oxide coin batteries, which are rated for 1.5V)
  • Comparatively stable voltage throughout their lifespan, but with a fairly sudden drop-off towards the end of their useful life
