ELI5: What does it mean for a battery to ''short-circuit''?
Now when a battery is put into a electrical circuit, the electrons want (well, of course they do not want to, as they do not have any will at all) to get away from the other electrons and have a bit more "me space" - which they can have on the other end of the battery, where it is less crowded, so to speak. So if a way opens, by the battery being put into a circuit, the electrons will take

OK, so if you directly connect the two terminals of a battery, there is very little resistance in the circuit and you will drain the battery very quickly. However if you have a very simple circuit, for example a light bulb connected to the battery, the battery will drain slowly based on the watts used by the light bulb.
