will not hold a charge
have 2 of the pink ones...we charge them but they will not hold the chargs....the green light goes on for a few seconds and then off...can these be saved?
as rab777hp said, it sounds like a dead battery - they don't last forever unfortunately.
there is a teardown for the iPod shuffle 2nd generation, here
unfortunately replacing the battery requires soldering, but if you can find a replacement battery and know how to solder, it should not be difficult to do it yourself
