# CR15H270 battery

**What replaces a CR15H270: CR15H270, DLCR2, EL1CR2, 5046LC, KCR2, RLCR2**

3 V lithium (primary), 15.6 × 27 mm (diameter × height)

The CR15H270 is a single-use 3 V lithium (primary) cylindrical. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** CR15H270
- **ANSI / NEDA:** 5046LC
- **Nominal voltage:** 3 V
- **Chemistry:** Lithium (primary)
- **Size:** 15.6 × 27 mm (diameter × height)
- **Typical capacity:** 800 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? |
| --- | --- |
| CR15H270 | Yes — same cell |
| DLCR2 | Yes — same cell |
| EL1CR2 | Yes — same cell |
| 5046LC | Yes — same cell |
| KCR2 | Yes — same cell |
| RLCR2 | Yes — same cell |
| CR-2W | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| 15270 / RCR2 | The rechargeable lithium-ion version at 3.7 V nominal. Higher voltage and about a third of the capacity. |
| CR123A | Larger in every dimension — 17 × 34.5 mm — and often confused because both are "3 V camera lithiums". |

> The CR15H270 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

- Instant cameras and older compact film cameras
- Golf rangefinders
- Some Sylvania and Streamlight torches
- Wireless door and window sensors

## Common questions

### What is equivalent to a CR15H270?

CR15H270, DLCR2, EL1CR2, 5046LC, KCR2, RLCR2, CR-2W — all the same 3 V cell under different manufacturer codes.

### Can I use a 15270 / RCR2 instead of a CR15H270?

The rechargeable lithium-ion version at 3.7 V nominal. Higher voltage and about a third of the capacity.

### Is the CR15H270 rechargeable?

No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
