Hit the reviews and see how many hours they get. If you've been around a while you learn to get double the battery hours you are wanting. Not many laptops get that many hours on a charge and since it's a 300 cycle battery in a year of such use you'll be getting a new battery. It seems new laptop owners learn this after they burn through their first battery. The lesson is you plug in when possible.
I am planning to be in Asia for 8 months and looking to purchase a new laptop. Specifically Dell E5530.
I am a desktop user so this is my first laptop.
My goal is to have 6 hours of battery life available, before recharging.
Activities include: web surfing, reading /writing on social networks play music videos, and once a week watch a movie.
I did a trial run build on Dell. website for E5530 laptop, .
These are some of my specs:
i7-3520M Processor 2.9GHz, Win 8 pro, 4G Ram 1600mhz, 320GB 7200rpm Hard Drive, 9 cell battery.
Given that I selected I7 processor and win 8, will my 9 cell battery be drain significantly per session?
Should I purchase a 9 cell slice battery to bring with me?
Based on my web activities (stated above), what would be your best guesstimate of battery life having one 9 cell battery?
