I got the VST charger and while it appears to work flawlessly, the problem now seems to be in the iBook itself.

The new battery took about 2-3 hours to charge (which I know is pretty typical for this battery). I put it in the iBook and it wouldn't start up without AC power. When I disconnected the AC adapter after booting, I got maybe 10 seconds of battery time until the computer went to sleep.

The control strip showed a battery icon only (just a picture of a little light blue AA battery). There was no meter when I disconnected the power, not even one with all white bars. The iBook somehow can see there is a battery, but has no idea how to read its capacity--a fully-charged battery should not show up as a nearly dead one.

I can't begin to tell you how many times I've reset the power management unit, zapped the PRAM, and ran the NVRAM commands. I haven't yet tried a clean system install but am thinking about doing exactly that today.

There is a always a chance I have now received two defective batteries in a row. I'd like to attempt to resolve this within the next two days so I can send back the items if I need to.

Clamshells have no backup battery. Not sure what else I could try as I've exhausted every method known to me for this.

For the record--the charger shows that my old batteries from ten years ago are both dead.
