Does the battery adhesive soften with temperature?

Has heating the battery compartment before removing the batteries been considered?

Lithium Ions get warm when recharging. Attaching them to the case can also allow the heat to be dissipated to the case. With most adhesives, heat sometimes softens them (for example, the Aircraft epoxy called Epibond 1020 softens at 300F). The question ends up being how far you warm them w/o damaging the case or batteries. Also see if those adhesive strips conduct thermally.

Could try isolating a piece of the double sided tape adhesive being used and subjecting it to heat by itself, and seeing if it softens.

iFixit has now developed a kit for removing the battery without using heat. Their release agent is acetone. I developed an answer a couple of years before them using methanol (but methanol is a more volatile chemical and more dangerous to use. Here's the updated guide for doing it:

Just a note - Acetone is actually more volatile than Methanol, and considerably more dangerous. Acetone is the reason illegal drug labs often go BOOM. Swab your hand with Acetone, see how long it stays on hand, then swab Methanol on hand - compare.

Acetone boils at 56.1C, vapor pressure 30.6kPa @ 25C, Flash point -17C

Methanol boils at 64.7C, vapor pressure 16.96kPa @ 25C, Flash point 11C

Just FYI.

Thanks for the info Bruce. Glad to know my original solution (pun intended) is a better choice.

Yes, But the temperature to soften the adhesive usually goes above the temperature limit for the batteries. Overheating the batteries not only seriously degrade its performance, but also can be a serious safety threat. So you either ruin the battery hot while removing them, or tear them cold while removing them. Either way the battery is barely reusable, if possible at all

Even mechanical stress during battery removal can render the battery unsafe. Apple stats clearly in the repair manual that battery removed from the iPhone should NEVER be reinstalled.

Wouldn't you be replacing the battery if your taking it out? Can't everything else be removed without taking out the battery (with exception to the track pad cable?)

People do strange things ;-} The other possibilities are: The case is damaged, or the track pad or keyboard needs replacing (both are under the battery).

Isopropyl Alcohol (IPA) in a very high concentration (>90%, if possible ~99%) will actually do the trick.

I was already suspicious that it could work since I accidentally caused some (unimportant) adhesive patches on a 13'' Unibody MBP (which had suffered a massive wine spill) to peel off after I submerged its parts in that stuff (guess what, the MBP worked fine afterwards! ;) ).

So, *even if you're just taking out the battery to repair the trackpad*, you can safely remove the battery without causing it any damage.

Check out this video for details on the procedure: http://www.youtube.com/watch?v=pLhHSIej9...

Hi try this technique.

I just removed a macbook pro A1502 battery with a card (credit card style) coated in eucalyptus oil.. removed in 3 minutes flat! No heating or prying.

Just a thought but based on some of the above comments it might be easiest to use a piece of metal wire and two plastic handles to separate the battery from the glue (similar to [ this ] YouTube process, but maybe less painful :). This procedure with metal wire and handles is already used to separate phone LCD Screens from the glass Digitizers on iPhones. You can find this type of wire and handles on [ Amazon ] or [ Ebay ] for pretty inexpensive, just look up something like: “Molybdenum Cutting Wire and handle.
