I have a laptop acer aspire 7720g. It has a 6 cell battery with 11.1 volts and 4000 mah with battery code AS07B31. I was just thinking of buying a new battery for my laptop, and was searching for one which would last more hours( current battery maximum of 2 hours). Apart from being the same size(and fit in laptop) what other factors should be the same so that it is compatible with my laptop? (voltage/ Mah/cell no)

Have a look here:

Your best bet to find a 9 cell battery would be to look on acer's support site and perhaps they can direct you to an online store where there is a compatible one. Either that or just contact Acer support.
