# CR2320 battery

**What replaces a CR2320: DL2320, ECR2320, BR2320**

3 V lithium (primary), 23 × 2 mm (diameter × height)

The CR2320 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:** CR2320
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 23 × 2 mm (diameter × height)
- **Typical capacity:** 135 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? |
| --- | --- |
| DL2320 | Yes — same cell |
| ECR2320 | Yes — same cell |
| BR2320 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| CR2330 | Same 23 mm diameter, 3.0 mm tall and roughly twice the capacity. Too thick for a CR2320 compartment. |
| CR2032 | Three millimetres narrower. It will rattle in a 23 mm holder and may lose contact. |

> The CR2320 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

- Memory backup in industrial controllers
- Some Citizen and Seiko watch modules
- Sports timing transponders
- Older PDA and organiser backup cells

## Common questions

### What is equivalent to a CR2320?

DL2320, ECR2320, BR2320 — all the same 3 V cell under different manufacturer codes.

### Can I use a CR2330 instead of a CR2320?

Same 23 mm diameter, 3.0 mm tall and roughly twice the capacity. Too thick for a CR2320 compartment.

### Is the CR2320 rechargeable?

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