Hi.

Don’t ask me, because I have this guide only translated not created. Try to contact the author on de.ifixit.com. I have translated it so, that I tried to don’t change the original text.

I didn’t get it quite clear: is there a original battery replacement or an improvised one? I am interested in replacing mine but I didn’t find the battery.

WTF?!? Don’t do this. Buy a replacement battery online, and swap it out. Don’t drill holes, add glue, and try to cram in some battery that isn’t built for it!
