Better battery for Acer 5570z laptop?

This laptop came with a 6 cell battery that lasts a little less than three hours. Up until now, I haven't had a problem with that. I've always used it plugged in. But now I've suddenly discovered the greatness of using a laptop as a laptop. I checked the Acer store, but the only battery listed for my laptop is the same one I have. They make 12 cell batteries, but they don't list my model as compatible!

Does anyone know where I can get a better battery? It sucks, but I'm starting to think no one makes one.

Well, you may have some luck finding one on Ebay. Perhaps someone may sell a battery with better cells, that will fit this computer? Check and see if you can get one with better specs. There are some batteries that are not made by the original manufacturer that are a direct fit for different laptops.
