My son's iPod Touch appeared dead because it couldn't be charged using the USB charger. An older model was charging on the same cable. As a last resort, I bought a wall charger and the iPod responded immediately. Is this typical when batteries are drained to the sub-basement, or does it indicate a problem with the iPod?

iPods can only charge via USB.

Do you mean it won't charge when connected to the computer? If that's the case, then yes - it's normal. If the battery is completely drained, it will take quite a bit longer to revive when charging from a computer vs a wall adapter.

The iPod didn't respond after 16 hours on one of the USB ports of my MacPro, while another iPod responded properly. I bought a wall charger with a USB adapter and that was the device that woke up the sleeping iPod immediately.

It's possible that the computer didn't provide enough juice to wake up the charging circuit on a dead battery. I haven't seen it happen, but it wouldn't surprise me.

There's a good chance that the wall charger with a USB adapter provides a lot more output that the Mac's USB port, and yes I have witnessed that such chargers will work when the Mac's USB port doesn't, and especially when the batteries are almost dead, but that wasn't with an iPod but they probably work about the same way.

But hopefully better than an automatic 12V charger that wouldn't charge a deader than dead 12V battery on our boat that a malfunctioning automatic bilge pump didn't switch off and drained the battery completely. Then I had to use another 12V battery to "jump start" the auto charger. Stupid design for a battery charger and it wasn't a cheapie either!! :(

Yup, stupid battery charger design, but at least our boat has dual batteries and a battery isolator switch that had been set for battery selection properly.

Not quite as easy for my wife's car that had its lights left on last year = dead battery and the auto charger wouldn't do anything and I didn't have a spare good battery to use, but the good news was, with the drain cause turned off and left for an hour or more, the dead battery got enough surface charge voltage to ket the charger know it was finally available to charge.

Why don't cars come with some sort of low voltage auto battery disconnect so that at least some starting current is left available for such situations?

With all the onboard computers providing a very slight continual drain I suspect anyone going out to start a car that had not been started for several months might also find a dead battery.

I've got an old UPS that won't take a charge, maybe I could work that into Macfury's USB thread also?
