ok well for the first part, losing 20% in 5 hours seems fine really, even if it is shut off, the battery will drain it has to keep the time etc etc, when you say that after it was shut off it was hot, are you sure the macbook is shut off and not asleep? also when you said you unplugged the battery and it cooled down what happens if you put the battery back in with the macbook off?

There's another internal battery that help keep time, etc. If you remove all external power sources including the removable battery the computer still keeps time; thus the clock doesn't drain that battery.

As for the drain, it's probably it's on "sleep mode" rather than "shut down"?
