Hello, I just purchased an Acer Aspire v17 nitro black edition notebook and while all specs look amazing, there is one that is not. The battery is only a 3 cell Li-ion battery with "up to 4 hours". This wouldn't really be a problem, if I didn't use it for work/school and could have it plugged in all the time. For this reason I am looking to purchase a replacement battery with more cells so that it has a longer battery run time but google searches have yielded no results. Does anyone know of a larger battery for this laptop? I have just ordered this laptop and it is still on it's way to be delivered so I do not have the SNID to talk with an Acer specialist and the "answers by acer" does not help whatsoever. Are all acer batteries interchangeable? Are at least all acer aspire batteries interchangeable? Or am I kind of out of luck with upgradeing this battery? Thanks for all help!
