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.

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.
