Codes that mean the same battery
| Code | Fits? |
|---|---|
| DL1225 | Yes — same cell |
| ECR1225 | Yes — same cell |
| BR1225 | Yes — same cell |
| KCR1225 | Yes — same cell |
| 5020LC | Yes — same cell |
| SB-T13 | Yes — same cell |
Codes that look close but are not
| Code | Why it is not a substitute |
|---|---|
| CR1220 | Same diameter, half a millimetre thinner. It seats loosely and holds about a quarter less charge. |
The CR1225 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
- Motherboard and embedded-system clocks
- Tyre pressure monitoring sensors
- Electronic candles and small toys
- Some Casio calculators
Common questions
- What is equivalent to a CR1225?
- DL1225, ECR1225, BR1225, KCR1225, 5020LC, SB-T13 — all the same 3 V cell under different manufacturer codes.
- Can I use a CR1220 instead of a CR1225?
- Same diameter, half a millimetre thinner. It seats loosely and holds about a quarter less charge.
- Is the CR1225 rechargeable?
- No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
