Same fit · different chemistry

CR2032 and ML2032 share dimensions but not the complete specification

The physical envelope and nominal voltage are close, but chemistry changes from Lithium manganese dioxide to Rechargeable lithium manganese.

Use only when the device maker explicitly approves both chemistry systems.

Why this verdict

  • The physical envelope matches.
  • Nominal voltage is close.
  • Chemistry and discharge behavior differ.

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.
