Comparison

CR2032 vs LIR2032

Same approximate 20 × 3.2 mm coin size — CR2032 is a 3 V primary Li-MnO2 cell; LIR2032 is a rechargeable Li-ion coin (~3.6 V). Not a drop-in replacement.

Same size family — different chemistry

Short answer

Do not put an LIR2032 in a device that names CR2032 unless the OEM explicitly allows a rechargeable coin. Higher voltage and different chemistry can damage electronics.

Only use LIR2032 when the device or OEM documentation names LIR / rechargeable coin explicitly.

What is the same

Roughly the same diameter and thickness class — they can look identical in a drawer.

What is different

CR2032: primary lithium manganese dioxide, ~3.0 V, not designed for recharge.

LIR2032: rechargeable lithium-ion, typically ~3.6–3.7 V nominal, lower capacity than primary CR2032, different duty cycle.

Do not use list

Do not treat LIR2032 as a “rechargeable CR2032.”

Do not confuse LIR2032 with ML2032 (another rechargeable class) or BR2032 (different primary lithium subclass).
