Li-ion BATTERY for Apple iPod Shuffle 2nd 3rd Generation 2gb 4gb 2 3 Gen 616-0274 616-0278 6160274
I bought this to install into my 2nd generation shuffle, but found the battery to be too thick to slide back into the casing. I tried all sorts of things to get the battery to fit, including trimming off the plastic cover, and even though I managed to get it wedged in, it's still so thick that it pushes the switches off-center and the buttons can't connect to them. I'm pretty sure I've voided the warranty and don't expect to get my money back, but I wanted to warn other DIYers out there.
