Re: a battery mystery...
As the elecrtrical current is passed from battery 1 to battery 2, a chemical reaction can occur in the contact points which causes corrosion. Might only be a very small spot if the batteries are cheap as they aren't uniformly flat. By swapping the batteries, you have given a new contact point which can again let the current flow as the corroded point has a lower level of conduction.

Re: a battery mystery...
No, I just love knowing how things work. But my step father was a Physics master at a grammar school as well!
Trouble is, I hated school and somehow ended up Getting a 'D' in physics! Couldn't be bothered with exams as a kid!

Re: a battery mystery...
being an electrical engineer, coxy's explaination is pretty bang on the money.
Plus, as you have removed the batteries, the little electrons get woken up and shaken about, thus your appliance works again,
they are lazy shit those electrons..
That is why you bang your remote control, when it doesnt seem to work..hey presto, a quick bang against your knee and the channel changes.
its all about the alternating current in the batteries...

Re: a battery mystery...
what's this licking batteries...vaguely remember that that had some sort of effect...can't remember what though...
