I've had a 5G 60GB iPod with Video since October of 2005 when they were released. When I was using it a few days ago, it was working just fine, and battery life seemed pretty normal. Last night, I was trying to use it, and no dice. It was as if it was trying to power up, the Apple logo would show, and then it'd go dark again. So I plugged it in to charge and left it overnight. It didn't take a charge at all. If i plug it into my external battery pack, it works fine, so I'm pretty certain that it's the battery. Naturally, I'm out of the 1 year warranty, so I expect I'll be getting a third party replacement battery at my expense. Thing is that this seems like a nonstandard battery failure. I'm familiar with how lithium ion batteries degrade over time, and I'm used to a failure mode that approximates a gradual decline in life, not a sudden complete failure. Anyone else seen a similar battery failure? Wondering if it might be worth my while to talk to Apple about this.
