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.
