Introduction

Replacing the battery requires a fine tip soldering iron and is a difficult job that only experienced solderers should attempt.

  1. Insert the edge of an iPod opening tool into the gap between the outer case and the top bezel. Pry the top bezel off the adhesive securing it to the display retainer.
    • Insert the edge of an iPod opening tool into the gap between the outer case and the top bezel.

    • Pry the top bezel off the adhesive securing it to the display retainer.

    • At this point the hold switch slider is free and may fall. Be careful not to lose it.

  2. Remove the hold switch slider from the top of the Nano.
    • Remove the hold switch slider from the top of the Nano.

  3. Remove the two angled Phillips screws from the two corners of the display retainer.

    • Insert an iPod opening tool between the outer case and the display retainer.

    • Use the tool to slide the display assembly out of the case slightly.

    • Do not rotate the display retainer about the top edge of the display, as it is attached to a thin steel bracket that is easily broken.

    • Do not forcefully remove the display retainer, as the hold switch cable is liable to snap.

  5. Slide the display out of the Nano. It will move about .5" until the display data cable limits its travel.
    • Slide the display out of the Nano. It will move about .5" until the display data cable limits its travel.

    • Do not put unnecessary tension on the very thin display data cable.

  6. With the display pulled out of the case as much as possible, gently press on the lower edge of the glass panel until it pops in slightly (~1 mm). Use your thumbs on the lower edge of the glass panel to slide the glass down and into the case until the top edge pops up out of the case.

  21. Pull the logic board assembly out of the outer case, minding the hold switch and click wheel cables that may get caught.
    • Pull the logic board assembly out of the outer case, minding the hold switch and click wheel cables that may get caught.

    • When reassembling, ensure the click wheel cable is toward the front of the Nano and not in the grooves on the side. If it is in the groove you will probably cut it while sliding the logic board into place.

  22. Peel the hold switch cable from along the edge of the battery and lay it aside. The hold switch cable is not attached to the battery. The battery is held on to the logic board by a strong adhesive. Force may be required to remove the battery from the logic board.

    • Pry the battery off the adhesive securing it to the metal tray on the logic board.

  23. The battery on the fourth generation nano is attached via solder pads with small holes that go through the battery ribbon cable and attach to flat pads on the face of the logic board. In this step, you will heat each solder pad individually while using a metal spudger to pry it up from the logic board. DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts have the potential to ruin the logic board.

    • DO NOT bridge the connection between the solder pads both on the board and on the ribbon cable with your spudger. Shorts have the potential to ruin the logic board.

    • Beware of overheating the board and the cable. Only hold the tip of the iron against the pad long enough to let the solder melt. Excess heat buildup has the potential to ruin the logic board or melt the ribbon cable. Consider letting the board cool off between melting each solder pad.

    • Start working from one side of the battery ribbon cable. In our case, we started on the left. Heat the leftmost solder pad while gently prying up from under the ribbon cable to free it from the board.

  24. Repeat the previous step for each of the two remaining pads, working either right to left or left to right. At this point, the battery should be free from the logic board.

There is one small point which is worth a mention here.After disconnnecting the screen by flicking up a little black bit on the ZIF Connector, I went on to open the next ZiF (The Click Switch)

Yes- bits of ZIF connector everywhere.I actually had to examine a new Click Switch circuit carefully to find that this one is different.

Yes - you flick the White bit. Do apple do this just to keep us on our toes?

I have taken the nano apart and started to use a solder iron to remove the old battery. I must have pulled on the battery before fully melting the solder and have pulled off two of the three tabs from the board.

Can this be fixed?

I tried what Bradley suggested because it really seems easier than to solder the new battery to the iPod circuit board, which is really tiny. Still I couldn't do it. The battery pads are very fragile and I had an hard time folding the leads and the battery circuit board so that it looked the way it originally was. This was the part where I failed because afterwards I wasn't able to insert the battery plus the iPod circuit board inside its case again and ended it breaking it.

When I soldered my battery in I first touched the top and bottom of the pads on the new battery with flux and then added a little solder to the top and bottom of the pads. When I put the pads in place I only had to apply a quick touch and it soldered on perfectly.

Overall it was a real pain! :)

After 3 hours of hard work I did it !

It's the first time I try such a job, and I found it "quite easy" to change the battery with the guide. Just follow the pictures and you'll be done.

The hard work for me was the solder part - and a friend of mine gave me a hand as he was more used to do this.

You can do it, it worth a try :)
