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

- CR2477
- Nominal voltage
- 3 V
- Chemistry
- Lithium (primary)
- Size
- 24.5 × 7.7 mm (diameter × height)
- Typical capacity

- Rechargeable
- No — never charge it
Codes that mean the same battery
| 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.
