CR2330 battery
What replaces a CR2330
DL2330, ECR2330, BR2330, KCR2330
3 V lithium (primary), 23 × 3 mm (diameter × height)
The CR2330 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
- CR2330
- Nominal voltage
- 3 V
- Chemistry
- Lithium (primary)
- Size
- 23 × 3 mm (diameter × height)
- Typical capacity
- 265 mAh
- Rechargeable
- No — never charge it
Codes that mean the same battery
| Code | Fits? |
|---|---|
| DL2330 | Yes — same cell |
| ECR2330 | Yes — same cell |
| BR2330 | Yes — same cell |
| KCR2330 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| CR2320 | Same diameter but 1 mm thinner and around half the capacity. |
| CR2032 | Nearly the same thickness but 20 mm across rather than 23. It will not make reliable contact. |
The CR2330 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
- Real-time clock backup in servers and NAS units
- Marine and aviation instrument memory
- Some medical telemetry devices
- Industrial handheld scanners
Rated at 255–270 mAh across Panasonic, Renata and Murata to a 2.0 V cut-off.
Common questions
- What is equivalent to a CR2330?
- DL2330, ECR2330, BR2330, KCR2330 — all the same 3 V cell under different manufacturer codes.
- Can I use a CR2320 instead of a CR2330?
- Same diameter but 1 mm thinner and around half the capacity.
- Is the CR2330 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
