Help Me Choose: Battery


When it comes to batteries, more cells mean more battery power. If you aren't sure how much battery life you need, it's better to choose a battery with more cells now than to have your laptop run out of power when you need it the most.
Battery life depends on how you use your laptop, so ask yourself these questions as you look over the table below:
  • Will my laptop be plugged in or unplugged most of the time?
  • Do size and weight matter when I travel?
