Same size · different voltage

LIR2032 and ML2032 fit the same case but are not electrically interchangeable

LIR2032 is rated at 3.6 V and ML2032 at 3 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: 3.6 V versus 3 V.
  • Chemistry also changes from Lithium ion to Rechargeable lithium manganese.

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.
