# 4LR44 battery

**What replaces a 4LR44: A544, 476A, PX28A, 28A, K28A, V4034PX**

6 V alkaline, 13 × 25.2 mm (diameter × height)

The 4LR44 is a single-use 6 V alkaline cylindrical. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** 4LR44
- **ANSI / NEDA:** 1414A
- **Nominal voltage:** 6 V
- **Chemistry:** Alkaline
- **Size:** 13 × 25.2 mm (diameter × height)
- **Typical capacity:** 178 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? |
| --- | --- |
| A544 | Yes — same cell |
| 476A | Yes — same cell |
| PX28A | Yes — same cell |
| 28A | Yes — same cell |
| K28A | Yes — same cell |
| V4034PX | Yes — same cell |
| L1325 | Yes — same cell |
| 4A76 | Yes — same cell |
| 1414A | Yes — same cell |
| GP476A | Yes — same cell |
| V34PX | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| 4SR44 / 544 / PX28 | The silver oxide version of the same 13 × 25.2 mm can, at 6.2 V with a flat discharge. In a bark collar it makes no difference; in a Pentax or Minolta camera meter that was designed around it, the alkaline's falling voltage shifts the exposure as it ages. |
| 2CR1/3N / PX28L | The lithium version: two 3 V cells for 6.0 V in the same shell, with a long shelf life and a genuinely flat curve. It is generally the best of the three, but some old meters were calibrated for silver oxide. |

> The 4LR44 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

- Dog bark and training collars
- Pentax, Minolta and Yashica film camera meters
- Medical instruments and glucose meters
- Some LED bicycle lights

> Four LR44 cells stacked in a metal tube. Prising one open gives you four LR44s, which is a known if inelegant way to source them.

## Common questions

### What is equivalent to a 4LR44?

A544, 476A, PX28A, 28A, K28A, V4034PX, L1325, 4A76, 1414A, GP476A, V34PX — all the same 6 V cell under different manufacturer codes.

### Can I use a 4SR44 / 544 / PX28 instead of a 4LR44?

The silver oxide version of the same 13 × 25.2 mm can, at 6.2 V with a flat discharge. In a bark collar it makes no difference; in a Pentax or Minolta camera meter that was designed around it, the alkaline's falling voltage shifts the exposure as it ages.

### Is the 4LR44 rechargeable?

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