# CR1225 battery

**What replaces a CR1225: DL1225, ECR1225, BR1225, KCR1225, 5020LC, SB-T13**

3 V lithium (primary), 12.5 × 2.5 mm (diameter × height)

The CR1225 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:** CR1225
- **ANSI / NEDA:** 5020LC
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 12.5 × 2.5 mm (diameter × height)
- **Typical capacity:** 50 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? |
| --- | --- |
| 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.
