Electronic – If I set a multimeter on ‘ohms’ and put it across a battery, does it short the battery


As the title says. I am not very good at electronics (I might have, uh, actually done this, for no good reason…). I am wondering now if I should be worried about the battery being damaged.

It depends on the meter and the battery. To measure resistance your multimeter actually applies some known voltage and measures the resulting current. Although it would be possible to discharge a small battery like a coin cell, I would guess that you are more likely to damage the meter.
