45 minutes - 2 hours
My iPod Nano is 6 years old and will not hold a charge for about a year now. Decided to replace the battery so I don't have to have it plugged in to use it.
Received the new battery and tools. The screwdriver is fine but the plastic tool to remove the ends broke right away. I used a small screw driver it worked fine. The hardest part of the job was trying to get the solder out of the holes to put in the new wires. I finally heated the solder and inserted a needle to leave a hole. All went fine from there. I have charged it overnight and will play it today non stop to see how long it lasts.
Hopefully the plastic tools are stronger. I saw one video that showed to use what I think is called desoldering strip. This sucks up the solder and if it clears the holes it would sure make it easier. Other than that it is pretty straight forward. I replaced the battery in my 20 Gig iPod and it went lots smoother.
