An A2000 with a battery that hasn't leaked?? Yet..

[new2amga]

Hello, I've just recently got back into playing with Amiga computers and had the good fortune to win myself an A2000HD and an A4000/40(?) with an A3640 card in it.  I was marveling at the motherboard the other day and catching my drool as I stared, and noticed that the battery for the clock is still on the motherboard for the A2000.. It doesn't appear to have leaked, but it looks kind of grubby, and I was wondering what kind of effort and tools it takes to remove these batteries?  It's a Barrel shaped looking thing with what looks like two arms that connect to the board.  Can anyone help me?  I appreciate the assistance.  Thank you.

EDIT :  The grubbiness appears to be the gunk build up that appears on some electronics while in houses with smokers.  There does not appear to be any bulging or cracks in the battery I can take a picture if anyone likes.  Just let me know.  Thanks.

So I can use my metal nippers to cut it off the board?  And this won't hurt the board in any way?  Does anyone have a tutorial for this sort of thing?  I'm terrible with a soldering iron, which is why I didn't go for an electrical engineering degree. :-P Thanks for the info.  I really appreciate the help.
