Good question! While the swelling will decrease as the battery gets colder, the effectiveness of the solvent will decrease as well.
So the trick is keeping the battery cold but allowing the aluminum uppercase to stay at room temp. Using a waterless Ice block you use to keep food cold should offer the cold to keep the battery under control as you allow the case to warm up.
The cold will also prevent the solvent to evaporate as quickly so you want to use less.
I would get a few sets of plastic cards to wedge underneath the battery cells as you free them up. You may need to re-cool your system and attack it again a few times. MacBook Pro 15" Retina Display Early 2013 Battery Replacement

I haven't tried to remove the battery yet. But one question. Would the dental floss method of cutting through the dissolved adhesive be safer?
