compaq R4035CA Battery

Hi. Ive owned my compaq R4035CA for a few weeks and had been waiting on my ordered 12 cell battery. The laptop itself is great, but when I bought it I knew I needed something more than the 8 cell. Im using it for school and battery life means a lot when you are at school from 830 am until 930 pm. So I ordered a 12 cell battery from Staples and it is completely wrong. The part number is the correct one that HP offers (everywhere I look online anyways) and the man who ordered it didnt contest when he was ordering it (minutes after I bought the laptop). The battery ordered is a long, skinny battery ( number ordered with: PB995A) and the battery that my laptop uses is a flat, wide, almost square one. I have found a 12 cell on a review by one of the admins here that seems to show the correct 12 cell : http://www.notebookreview.com/default.asp?newsID=2395

Please, if anyone could tell me the part number for this battery, I would be forever thankful. Times running out before school starts and i dont want to be left with a semi-useless laptop.

thanks,
kyle
