I recently took apart my laptop and upgraded the CPU and added an internal wireless card (mini-PCI). Anyway now I'm looking to rebuild the battery using better power cells but i need some advice. My battery's part number is PA3251U-1BRS, and it says "4300 mAh" which i have gathered means 4300 mili-amp hours. I have also learned online that my pack supposedly has 8 power cells. I was looking at the 'standard' (i haven't opened the battery yet) power cells and the best ones are 2600mAh each (http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=2763). I think you add mAh together to get total power, but that would mean my battery would have something like 20,800 mAh (almost FIVE times the power if my battery were new). Is that right? can the circuitry in my battery handle that (ie would it work)? If anyone has had any experience rebuild batteries or knows about electrical engineering I would be very greatful. Thanks!
