Same here on a Eee PC 900 (Celeron-M) and 10.04. After logging in the battery indicator says there's only 1.9% left but the indicator itself shows the battery is full. Then the indicator reflects the drainage of the battery until it's about at 55-60%, then it suddenly drops to 20% (red indicator). I never actually saw it make the sudden drop but it always happens suddenly but at about the same interval (after an hour or so). It then stays at 20% for at least one hour, then it drops to 10% and after 30 minutes it's all over and done with.
After plugging it into the socket I noticed when starting up the BIOS asks for the time again. No relation with the Ubuntu battery indicator I guess but I thought I'd just mention it.
