Anyone here know how to refurbish an old laptop battery?

Your not going to "refurb" an ancient laptop battery for less then $50. You can buy new lithium cells, get around the same voltage. But it wont be cheap.

As for model number my computer is a Gateway Solo Pro 9300 if that helps.

Hmm, the site I linked doesn't have it.

Well, here's the details on what you wanna buy:

Searching for the part number of that battery: 6500358 may turn up some good deals, but I haven't purchased anything from any of the sites I saw on google so I can't recommend any suppliers.
Yeah, $50 is kinda expensive. I've ordered new batteries that work well for a few different laptops and never paid over $30.
The part no. seems to turn up more reasonable prices on Ebay.
