May have just been a false end-of-charge detection with the new battery. How long has it been charging the second time? It should take 6 hours max (3 max if you have a grey charger). Once it's done, unplug the charger, remove the battery, then put the battery back in and try charging again. It _should_ stop charging (turn green) in about 10 minutes this time, meaning it knows the battery is full.
If that doesn't fix it, it's possible the charging transistor in the roomba is blown, i've heard of that happening. Call the iRobot tech support line for help in that case.
