Well, pooey. Apple updated their list of recalled batteries and mine is one of 'em. I wonder if that's why the thing gets so incredibly hot...

So, if you have a Mac with a battery that you've bought in the last 3 years, go to www.apple.com/support and see if yours is on the list!

Apple will send you a new one (free) with a pre-paid envelope so you can then send 'em your old battery.

Meanwhile, don't use the battery. Take it out and just use the adapter.
