# LIR2032 battery

**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.

## Common questions

### What is equivalent to a LIR2032?

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

### Can I use a CR2032 instead of a LIR2032?

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.

### Is the LIR2032 rechargeable?

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