What is equivalent to a LIR2032?

LIR2032H, ML2032 (similar role, manganese-titanium chemistry) — all the same 3.6 V cell under different manufacturer codes.

Is the LIR2032 rechargeable?

Yes. Use a charger made for its chemistry and never substitute a primary cell of the same size.

What replaces a LIR2032

LIR2032H, ML2032 (similar role, manganese-titanium chemistry)

3.6 V lithium-ion (rechargeable), 20 × 3.2 mm (diameter × height)

The LIR2032 is a rechargeable 3.6 V lithium-ion (rechargeable) coin cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

Specification

IEC designation: LIR2032
Nominal voltage: 3.6 V
Chemistry: Lithium-ion (rechargeable)
Size: 20 × 3.2 mm (diameter × height)
Typical capacity: 40 mAh
Rechargeable: Yes

Codes that mean the same battery

Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.
Code	Fits?
LIR2032H	Yes — same cell
ML2032 (similar role, manganese-titanium chemistry)	Yes — same cell

Codes that look close but are not

Code	Why it is not a substitute
CR2032	The same 20 × 3.2 mm can, and the single most dangerous confusion in this file. The LIR is rechargeable lithium-ion: 3.6 V nominal, 4.2 V fully charged, and about 40 mAh against the CR2032's 225. Putting a CR2032 into a device that charges its coin cell can make it vent, rupture or ignite. Putting an LIR into a device that expects a CR gives you a fifth of the runtime at a voltage the circuit may not tolerate.

Where it turns up

Devices with a built-in coin-cell charging circuit
Some Bluetooth beacons and smart rings
Solar-charged sensors and trackers
Development boards with backup charging

Capacity 35–45 mAh depending on brand. Only fit one where the device is designed to charge it; nothing about the outside of the cell tells the device which chemistry it has.
