CR1620 stands for a lithium manganese dioxide battery (round shape) having a 16 mm diameter and 2 mm thickness.

  • The letter C indicates the chemical composition used in the battery (here ie, Lithium Manganese Dioxide)
  • The letter R indicates the shape of the battery (here ie, Round)
  • The first two digits indicate the battery’s diameter in millimeters (here ie. 16mm)
  • The second two digits indicate the battery’s thickness (here ie. 20mm)

  • DL1620
  • VCR1620
  • KCR1620
  • KECR1620
  • KL1620
  • L1620

Here, it is evident that only the alphabets are different. The last four numerals are the same. Hence all these equivalents are replaceable with CR1632 but they differ in performance.

Note: The other chemistries may not offer the same features as the lithium-manganese dioxide chemistry. So it is necessary to verify the power requirements of the device before using an equivalent in the place of CR1632.
