If your battery is unhealthy after less than 6 months you should try to get a replacement from dell. You have posted to a forum that requires a moderator to approve posts before they are publicly available. A 9 cell battery usaully last around 4-6 hours.
A starter can kill a battery quickly if it is drawing to many amps. Typically a battery will last up to 5 years if maintained properly and yes I have seen them last for as long as 12 years but this is a rare item to last that long especially on todays cars and the poor maintenance habits of todays drivers.
