I got one of these in this week with a wine spill. An uppercase replacement part priced out at around $700. I took a hypodermic syringe and filled it with methanol and shot about 3 cc of it around each of the batteries. Let it sit for 10 minutes and rocked it a few times to get the alcohol as deep as possible. Then I used a putty knife. I inserted it on the outside batteries first from the side closest to the keyboard. As each battery came up I laid it back. It took less than 5 minutes to have the battery out and in good shape. Looks like prices run from $75 to over $150 for replacement batteries. On mine I needed to replace the keyboard but that's another story. I found a new part in China with keyboard for $158. I'll end up with a new upper case replacement and save $525 making the repair feasible. New trackpads are also available on eBay.
