I'm looking for battery for my laptop Acer Aspire 7745G. I need the largest possible capacity and for me it doesn't matter how heavy it is. As I read in Acer website, more cells means higher weight and capacity. But I didn't find explanation anywhere what's bond between mah and cells quantity. After all, mah also means battery capacity. Maybe you could also recommend me battery for Acer Aspire 7745G?
