iBook Clamshell battery won't take full charge.

Right, so this battery is a few years old now, but until just a little bit ago, it was working fine for me. I bought the battery new in 2004 and used it pretty lightly since. The iBook also had the logic board replaced in 2003. Basically when I plug in the power supply, it won't charge the battery more than 4-7% at a time before the light goes green and the iBook thinks the battery is full. If i reset the PMU or remove and replace the battery, it will charge another 4-7% and then think its charged again. I have tried all the tricks I know to get this fixed. Reset the PMU, PRAM, and did a few Firmware resets all in different combinations and still no luck. I also took out the battery and let it all just sit for a day to let the Mac rest. Anyone have anymore ideas to get this thing to charge again? I like having this Mac on battery power becuase my MacBook Pro is set up as a "desktop" computer and my Powerbook G3 doesn't have a wireless card. I know you "Applefritterers" are some hardcore Mac guys like me and know the ins and outs better than just about anybody. Thanks for the help guys.

Do the PMU reset as described

Do the PMU reset as described, but don't remove the battery unless it's one of the older models with the reset button by the A/V port.

EDIT: So I just reread and saw that's it's a clamshell. I had a Dual USB in mind...

battery contacts?

I recently bought a new clamshell battery off ebay. The contacts weren't properly mating, so it did the same thing you described. Putting a folded-up business card above the mating point and then closing the battery hatch over it fixed the problem!
I ended up getting a refund for the battery.
