Removal of glued in Batteries

Dan suggested I let you know my results on this from a question I answered. https://www.ifixit.com/Answers/View/2015... I got in a wine damaged MBP retina A1398 EMC 2745 dual graphics Late 2013 with a shorted out keyboard.

"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."

"Dan, the methanol had very little liquid residue as it evaporates very quickly and has no water in it like rubbing alcohol. When burning in something like an alcohol torch it doesn't sputter. It can be obtained at dental supply places. I did not know if it would work, thus I didn't take photos for a guide. But this method will make a lot of the newer machines repairable. The iFixit team took 30 minutes to get their battery out. Mine came out very clean and is totally reusable."

The wide flat putty knife can be used to exert gentle upward pressure on the bottom of the battery without damaging it. Extreme caution should be used with methanol as it is highly volatile. A repairman can get familiar with it here: http://www.methanol.org/health-and-safet...

Methanol is also a hazardous chemical with significant toxic, flammable, and reactive properties that can produce deleterious impacts on human health and the environment when not properly handled.
