While the cells are easily replaced, it might be even easier to buy an aftermarket battery off eBay. Just search for HP 97 battery. Looks like $15 is the going price.

I agree. Nicad cells almost always fail by shorting out, the charger is not current limited so it's getting really hot becasue it's looking at almost a dead short (only one of the 4 cells is accepting any current). Mostly likely your 97 and charger will work fine with a new battery pack.
