My battery on iPod Video 30Gb died, so i replaced for a new one. But my iPod wont charge throught the usb 2.0 ports on my Mac, tried the block charger and that doesnt work. I tried another new battery and the same problem. I tired a new cable same results. any ideas?

I would at first check the voltage of the batteries with a multimeter. if the voltage is to low - it wont charge (usb) or could take long to show sings of charging (wall charger). the logic board could be the problem, but as i wrote before, check the voltage first. you can also measure the battery contacts on the logic board - remove the battery, plug in the usb cable and measure the voltage on the logic board (i mean the battery contacts ;-) )

Since it’s under warranty contact Apple support. If this answer is acceptable please remember to mark it. Good Luck, N.

The logic board which hold the charging unit is what goes bad. I dont know what causes it but i have seen a few cases where the battery just wont charge. its a hit or miss but the logic board would be the first place i would check. in all my cases it was just a matter of replacing the logic unit. BEFORE YOU go and order a part and try to fix it just look inside the charing port of your iPod and make sure there nothing in there.. sometimes its just a piece of lint stuck in there. =) iPod Video (30 GB) Logic Board

I have 1) 30GB and 1) 80GB iPod videos. The 30GB got a new battery installed by apple for free after the warranty was up (years ago). It would never charge. Apple told me that the logic board would need to be replaced for $200. I declined seeing how that iPod stayed at work in a dock.

My 80GB iPod always stayed in the car hard wired through the bottom port. A month ago I noticed this iPod case was split at the top. I ordered a battery and replaced it. It would not charge. I ordered another battery from a different place and I have the same problem. I know this iPod’s charging circuitry worked fine.

Is there any way to revitalize a new dead battery?
