iPod Battery Gone - Not The Battery's Fault
After many years of solid use, the battery slowly stopped holding a charge. One day, it simply wouldn't boot up long enough to be useful. After a little research, I self-diagnosed the problem as a bad battery, so I purchased a new one from iFixIt. Unfortunately, that was not the solution to my problem. Read on...
First of all, the plastic opening tools - even at $1 each - are not worth the money. The tip of one tool broke on my second attempt to open the iPod case. I ended up having much more success with a guitar pick and a miniature screwdriver (just be careful with the screwdriver as you can easily scratch the plastic case).
After finally getting the case open, I had no problems following the guide on iFixIt. I noticed that the battery I bought wasn't really rectangular - the adhesive on the back was kind of misshapen. It seemed to fit fine, though, and I was able to put everything back together without any mishaps. Unfortunately, it turns out the battery was not the problem - at least, not the only problem. Most likely, my logic board is bad, so on to the next repair job...
As mentioned, don't bother getting the plastic opening tools - try a guitar pick and a small screwdriver.
