CR2012 drawn to scale: 20 mm across and 1.2 mm thick, beside a US quarter at 24.26 mm across. US quarter Ø 20 mm 1.2 mm thick
CR2012 at actual relative size: 20 mm across, 1.2 mm thick. The dashed circle is a US quarter, 24.26 mm across (US Mint coin specifications).

CR2012 equivalents

Similar size, check the fit

Same diameter, different thickness. These are not drop-in replacements.

Cell Size Verdict
CR2016 20 × 1.6 mm Same 20 mm diameter, but 1.6 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.
CR2020 20 × 2 mm Same 20 mm diameter, but 2 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.
CR2025 20 × 2.5 mm Same 20 mm diameter, but 2.5 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.
CR2032 20 × 3.2 mm Same 20 mm diameter, but 3.2 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.
CR2040 20 × 4 mm Same 20 mm diameter, but 4 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.
CR2050 20 × 5 mm Same 20 mm diameter, but 5 mm tall instead of 1.2 mm. Only if the holder fits; thinner cells can lose contact.

Do not use

These are the same size or a similar code, and they are not equivalents.

  • LIR2012

    Rechargeable Li-ion: 3.6-4.2 V and far less capacity; only for devices built for it.
