[sdiy] Poly 61 near death?

[Joseph Palermo]

I just got a poly 61 of a friend who had It sittin in his basement. Most 
of the keys are not working properly, they don't trigger on the first 
hit, takes a couple, some not at all. And after being on for about 5 
minutes it restarts it self. I took a look under the hood and noticed a 
large battery on the cpu board, it has a small amount of leakage, bout 
the size of a nickle, I'm guessin I need to get it out of there asap. 
What should I do, I know of the poly 6 battery probs, is the poly 61 
heading for the same fate.

Thanks in advance
