My iPod mini's battery didn't work since 4 years ago. I had tried to contact Apple and ask for help but there were always trouble, and they even declare my device obsolete!!! I was about to lose any hope but then a friend told me about iFixit and I could finally repair the iPod, which now works perfectly!!
It was easier than I expected. The worst part was to remove the plastic covers, I had to force them and now they are a bit deformed. Taking away the old battery wasn't easy. The rest was easy and really interesting and fun!! I am electronic engineer and I loved to see the "guts" of the iPod. It took me about half an hour.
I think the instructions were clear so my advice would be just being patient and careful.
