Codes that look close but are not

Code Why it is not a substitute
SR41 / 392 Silver oxide in the same can, 1.55 V held flat. The better choice in anything that measures.
LR44 Far larger — 11.6 × 5.4 mm against 7.9 × 3.6. The names differ by one digit and the cells are not close.

The LR41 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

Common questions

What is equivalent to a LR41?
192, AG3, LR736, L736, V3GA, GP192, G3A, SG3, RW87, 384A — all the same 1.5 V cell under different manufacturer codes.
Can I use a SR41 / 392 instead of a LR41?
Silver oxide in the same can, 1.55 V held flat. The better choice in anything that measures.
Is the LR41 rechargeable?
No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
