Same size · different voltage

CR2032 and LIR2032 fit the same case but are not electrically interchangeable

CR2032 is rated at 3 V and LIR2032 at 3.6 V. Matching dimensions do not make cells with materially different nominal voltages safe replacements.

Use the exact voltage and battery system specified by the device manufacturer.

Why this verdict

  • The physical envelope matches.
  • Nominal voltage differs: 3 V versus 3.6 V.
  • Chemistry also changes from Lithium manganese dioxide to Lithium ion.

What to verify in the device

Check the original compartment label, the current manual, polarity, terminal style and whether the device explicitly permits a chemistry or rechargeable alternative.
