I know there have been some threads related to batterries and compact macs, and if they should be removed for storage, so forgive me if I'm repeating myself.

I have quite a few compact macs, and unfortunately due to limited space I have to store about half of them. Besides the obvious advice of having it in a dry area, I was wondering what's the best to preserve it in working order.

Ie, is it a good idea to turn it on every now and then? If so, how often. Does storage increase the posibility of leaky capacitors or other faults?

I mainly have everything from the mac plus up to store
