Thanks for all your hard work! I have used this to tackle replacing a battery. As you say, it’s NOT easy! I thought I’d let you know I have managed to do it. I found a battery for £21.50. I didn’t bother taking the feet off, I did heat the case with a hair dryer and was attempting to remove the base from the the internal structure, using a few ‘plectrum’ prying leavers … !! but somehow I managed to release a couple of the four clips, I went on to undo the others and it opened! The motherboard does need to come off to get the battery ribbon under it. Out of curiosity I wondered if I could do it again, and I did! There is a knack to it, but it does save the un-gluing! Why so much glue under the battery! it ain’t going anywhere with the tight fitting enclosure around it. I removed all the double sided tape off the new battery before installing it, in case I replace it again in the future. Thanks!! For the cost of the battery I now have a piece of Apple E waste that’s now worth £40-£50!
