Get longer battery life and improved laptop performance with an Alienware W670 battery.

This W670 battery is compatible with the AlienWare M15X laptop models. A full list of compatible laptop battery part numbers can be found below.

We use the highest quality lithium-ion battery cells and components that charge faster and last longer than cheap and low quality batteries. Low quality batteries use inferior cells that can wear out very quickly. In fact, most of our customers had previously bought a cheap battery but was no longer good after a few months. Our batteries can last up to 5 years.

We're so confident in our quality that each W670 battery is backed by a 1 year warranty and 30 day money back guarantee.

You can expect about 3 – 5 hours of run time with this AlienWare W670 battery. You can get even longer battery life by dimming your screen and closing unused programs.
