Codes that look close but are not

Code Why it is not a substitute
LR927 / LR57 / 195 Alkaline, 1.5 V, sloping discharge, roughly a third of the capacity.
SR920SW / 371 Same diameter, half a millimetre shorter. It sits loose and cuts out under vibration.

The SR927SW 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.

Common questions

What is equivalent to a SR927SW?
395, 399, SR57, SR927, SR927W, SR926, AG7, D395, V395, 1162SO, GP395, SB-AP — all the same 1.55 V cell under different manufacturer codes.
Can I use a LR927 / LR57 / 195 instead of a SR927SW?
Alkaline, 1.5 V, sloping discharge, roughly a third of the capacity.
Is the SR927SW rechargeable?
No. It is a primary cell — charging one risks rupture or fire. Rechargeable look-alikes exist in the same size under different codes.
