How ifixit saved me loads of money
5 - 10 minutos
I was recharging my battery and suddenly at about 69% it stopped charging and this "battery service needed" message box appeared. Still it worked but it was a major bummer to see that my battery would now only last for about 1 1/2 hours. So I went to pretty much any local apple store. One was unable to order the battery, the other ones wanted that i send my macbook in for repair because they need the damaged battery, which didn't work out for me as i need it on a daily basis because of my job. i thought that this is a bit ridiculous of apple and was very happy that i've found the ifixit website and ordered my new battery which arrived exactly 72 hours after my order from california to austria! a thousand thanks for this! that's what i call a quick service. all thumbs up!
As i've exchanged RAM and my fan already a few months ago (and also had a lot of experience with replacing PC parts in the past) I knew already that it wouldn't be that hard. After reading the ifixit guide the repair worked very flawless. didn't take me five minutes to do it. i didn't take any pictures because of the lack of a camera but i thought there are already a dozens on here already.
Everyone can do this (especially those of us who didn't pay for applecare protection plan) and for sure no one should spend loads of money that a apple service technician loses some screws, and replace that battery (and leave me with a week of no income) for a job done in 5 minutes... ;)
