Help Me Choose: Battery

Battery life is an important factor when you are deciding on a laptop. Whether you work long hours on the road or spend the majority of your time plugged into a power dock, find the best option to meet your needs.

Dell laptops come with one of two kinds of batteries:

Swappable battery

  • easily removable
  • swap out a fully charged spare battery*
  • ideal if you work long hours unplugged on the road or in the air

Built-in battery

  • fits thin and light laptops, like XPS and Inspiron 7000 Series
  • ideal for lightweight travel
  • easy to pack
  • charges with an optional portable adapter*

The more cells, or the higher the watt-hours powering the same laptop under the same operating conditions, the longer the battery will last when unplugged from an outlet.
