It could be the battery itself is bad or it could be a fault in the power supply module or the charging circuit. its very awkward to tell without viewing the machine.
you've already ruled out the probability of it being the AC power cables however it seems a bit peculiar that on both of them the green light on the box goes off.
May be best to ring Dell support for further advice and see if they can come up with any further ideas. Dell are specific with their parts unfortunately.

It seems like you may be agreeing with me here Mike. Thankyou it gives a Trainee MCSA a great sense of achievement.
