# CR2032 battery

**What replaces a CR2032: DL2032, ECR2032, KCR2032, LM2032, SB-T51, BR2032L**

3 V lithium (primary), 20 × 3.2 mm (diameter × height)

The CR2032 is a single-use 3 V lithium (primary) coin cell. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** CR2032
- **ANSI / NEDA:** 5004LC
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 20 × 3.2 mm (diameter × height)
- **Typical capacity:** 225 mAh
- **Rechargeable:** No — never charge it

## Codes that mean the same battery

*Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.*

| Code | Fits? |
| --- | --- |
| DL2032 | Yes — same cell |
| ECR2032 | Yes — same cell |
| KCR2032 | Yes — same cell |
| LM2032 | Yes — same cell |
| SB-T51 | Yes — same cell |
| BR2032L | Yes — same cell |
| CR2032H | Yes — same cell |
| L14 | Yes — same cell |
| 5004LC | Yes — same cell |
| EA2032C | Yes — same cell |
| DL2032B | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| LIR2032 | Rechargeable lithium-ion at 3.6 V nominal and 4.2 V charged, in the same 20 × 3.2 mm can. It holds about a tenth of the charge and its higher voltage can damage the device. Critically, the reverse swap is the dangerous one: a CR2032 dropped into a charging cradle can vent, rupture or catch fire. |
| CR2025 | Same 20 mm diameter but 2.5 mm thick instead of 3.2. It sits loose in a CR2032 holder and carries about a quarter less charge. It often works; it also often loses contact when the device is knocked. |
| BR2032 | Same size and 3 V, but lithium/carbon monofluoride rather than lithium/manganese dioxide: roughly 190 mAh and a much lower peak current. Excellent for memory backup and for −30 to +80 °C service, weak in anything that pulses hard like a key fob. |

> The CR2032 is a primary cell and must never be put in a charger. Charging a sealed primary battery builds gas pressure inside a can with no vent designed for it, which is how they rupture or catch fire. Rechargeable look-alikes exist for several sizes and carry different codes — check the code, not the shape.

## Where it turns up

- Motherboard CMOS clock and BIOS settings
- Car key fobs and garage remotes
- Bathroom and kitchen scales
- Fitness trackers and bike computers
- Tile and AirTag-style trackers

> Rated capacity varies by brand and by the load it is measured at: Energizer publishes 235 mAh, Panasonic 225 mAh, Duracell around 220 mAh, all to a 2.0 V cut-off. Swallowing one is a medical emergency in children — a lodged 20 mm lithium cell burns through tissue within hours.

## Common questions

### What is equivalent to a CR2032?

DL2032, ECR2032, KCR2032, LM2032, SB-T51, BR2032L, CR2032H, L14, 5004LC, EA2032C, DL2032B — all the same 3 V cell under different manufacturer codes.

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

Rechargeable lithium-ion at 3.6 V nominal and 4.2 V charged, in the same 20 × 3.2 mm can. It holds about a tenth of the charge and its higher voltage can damage the device. Critically, the reverse swap is the dangerous one: a CR2032 dropped into a charging cradle can vent, rupture or catch fire.

### Is the CR2032 rechargeable?

No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
