# CR2477 battery

**What replaces a CR2477: DL2477, ECR2477, BR2477A, CR2477N**

3 V lithium (primary), 24.5 × 7.7 mm (diameter × height)

The CR2477 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:** CR2477
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 24.5 × 7.7 mm (diameter × height)
- **Typical capacity:** 1000 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? |
| --- | --- |
| DL2477 | Yes — same cell |
| ECR2477 | Yes — same cell |
| BR2477A | Yes — same cell |
| CR2477N | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| CR2450 | Same diameter, 2.7 mm shorter. It will drop into a CR2477 holder without reaching the top contact. |

> The CR2477 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

- Long-life asset and cargo trackers
- Industrial sensors and data loggers
- Utility and gas meter memory backup
- Some cochlear implant remote controls

> The largest common lithium coin cell. Rated capacity spans roughly 950–1000 mAh across Panasonic, Renata and Murata to a 2.0 V cut-off.

## Common questions

### What is equivalent to a CR2477?

DL2477, ECR2477, BR2477A, CR2477N — all the same 3 V cell under different manufacturer codes.

### Can I use a CR2450 instead of a CR2477?

Same diameter, 2.7 mm shorter. It will drop into a CR2477 holder without reaching the top contact.

### Is the CR2477 rechargeable?

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