# CR-P2 battery

**What replaces a CR-P2: 223, 223A, CR17-33, DL223A, EL223AP, 5024LC**

6 V lithium (primary), 35 × 19.5 × 36 mm

The CR-P2 is a single-use 6 V lithium (primary) prismatic. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** CR-P2
- **ANSI / NEDA:** 5024LC
- **Nominal voltage:** 6 V
- **Chemistry:** Lithium (primary)
- **Size:** 35 × 19.5 × 36 mm
- **Typical capacity:** 1500 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? |
| --- | --- |
| 223 | Yes — same cell |
| 223A | Yes — same cell |
| CR17-33 | Yes — same cell |
| DL223A | Yes — same cell |
| EL223AP | Yes — same cell |
| 5024LC | Yes — same cell |
| K223LA | Yes — same cell |
| CRP2 | Yes — same cell |
| 6204 | Yes — same cell |
| BR-P2 | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| 2CR5 | The other 6 V photo lithium, 34 × 17 × 45 mm with a different terminal layout. They are not interchangeable in either direction despite both being "6 V camera batteries". |
| Four AA cells | Four alkaline AAs also make 6 V, and adapter trays exist, but they cannot supply the flash-charging current a CR-P2 was chosen for. |

> The CR-P2 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

- Film SLRs and medium format backs
- Automatic taps and hands-free flush valves
- Some Sloan and Toto sensor plumbing
- Older camera flash units

## Common questions

### What is equivalent to a CR-P2?

223, 223A, CR17-33, DL223A, EL223AP, 5024LC, K223LA, CRP2, 6204, BR-P2 — all the same 6 V cell under different manufacturer codes.

### Can I use a 2CR5 instead of a CR-P2?

The other 6 V photo lithium, 34 × 17 × 45 mm with a different terminal layout. They are not interchangeable in either direction despite both being "6 V camera batteries".

### Is the CR-P2 rechargeable?

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