# 2CR1/3N battery

**What replaces a 2CR1/3N: PX28L, 2CR11108, K28L, L544, 28L, EL2CR13N**

6 V lithium (primary), 13 × 25.2 mm (diameter × height)

The 2CR1/3N is a single-use 6 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:** 2CR1/3N
- **Nominal voltage:** 6 V
- **Chemistry:** Lithium (primary)
- **Size:** 13 × 25.2 mm (diameter × height)
- **Typical capacity:** 160 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? |
| --- | --- |
| PX28L | Yes — same cell |
| 2CR11108 | Yes — same cell |
| K28L | Yes — same cell |
| L544 | Yes — same cell |
| 28L | Yes — same cell |
| EL2CR13N | Yes — same cell |
| 2CR-1/3N | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| 4LR44 / A544 | Alkaline in the same can at 6.0 V, cheaper, with a sloping discharge and a much shorter shelf life. |
| 4SR44 / 544 | Silver oxide at 6.2 V. Slightly higher voltage; some vintage meters were calibrated against it. |
| CR1/3N | A single 3 V cell of the same diameter and a third the height. Two of them in series make this battery, and one of them is half the voltage. |

> The 2CR1/3N 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 camera meters wanting a decade of shelf life
- Bark and training collars in cold weather
- Medical and veterinary instruments
- Wildlife and trail equipment

> Two CR1/3N lithium cells in series. Capacity around 150–170 mAh, but with a ten-year shelf life and a flat curve, which is why it outlasts its milliamp-hour rating in practice.

## Common questions

### What is equivalent to a 2CR1/3N?

PX28L, 2CR11108, K28L, L544, 28L, EL2CR13N, 2CR-1/3N — all the same 6 V cell under different manufacturer codes.

### Can I use a 4LR44 / A544 instead of a 2CR1/3N?

Alkaline in the same can at 6.0 V, cheaper, with a sloping discharge and a much shorter shelf life.

### Is the 2CR1/3N rechargeable?

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