CR2450 battery
What replaces a CR2450
DL2450, ECR2450, KCR2450, BR2450, 5029LC, SB-A8
3 V lithium (primary), 24.5 × 5 mm (diameter × height)
The CR2450 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.

- 3 V
- Chemistry
- Lithium (primary)
- Size
- 24.5 × 5 mm (diameter × height)
- Typical capacity
- 620 mAh
- Rechargeable
- No — never charge it
Codes that mean the same battery
| Code | Fits? |
|---|---|
| DL2450 | Yes — same cell |
| ECR2450 | Yes — same cell |
| KCR2450 | Yes — same cell |
| BR2450 | Yes — same cell |
| 5029LC | Yes — same cell |
| SB-A8 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| CR2477 | Same 24.5 mm diameter but 7.7 mm tall instead of 5.0. It carries far more charge and will not close a CR2450 compartment. |
| CR2430 | Same diameter, 3.0 mm thick. It rattles in a CR2450 holder and holds about half the charge. |
| LIR2450 | Rechargeable at 3.6 V nominal. Never charge a CR2450. |
The CR2450 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
- Smart door locks and Yale/August keypads
- Zigbee and Z-Wave door and motion sensors
- Blood glucose meters
- Heated ski gloves and electric-scooter remotes
Common questions
- What is equivalent to a CR2450?
- DL2450, ECR2450, KCR2450, BR2450, 5029LC, SB-A8 — all the same 3 V cell under different manufacturer codes.
- Can I use a CR2477 instead of a CR2450?
- Same 24.5 mm diameter but 7.7 mm tall instead of 5.0. It carries far more charge and will not close a CR2450 compartment.
- Is the CR2450 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
