8 Cells Battery – HP 530

Hey, I was wondering how much would it last?
HP 530, Windows XP SP3, and regular working, browsing the web, music, videos etc…
I tried checking in HP websites and google but didn’t get an answer…
Thank you!
Answer #1
I don’t know what processor it’s got.
I get about 4 1/2 hours out of a six cell with a i7 GT540M Acer, doing the same stuff.
I’d guess about 5 to 5 1/2 hours, maybe?
