Ok, so the ist thing to do is to weigh the 2 batteries.
 The 9 cell should be  approx 1/3rd heavier.
 Let us know what the weights are. If there the same then youve probably 
got a 6 cell with a 9 cell label on it.

The other way is to get the 2 batteries x rayed. tho it might screw uo 
the battery electronics.
 thatssomething I wouldnt know about.
 
 A genuine IBM  would im sure be heavier and give you the battery life 
you hope  for.
