Suitable for users whose original battery no longer holds a useful charge and who have verified their model against the listed part numbers. Not for owners of Asus models outside the compatibility list, nor for anyone requiring a different voltage or cell count. Buyers who need higher capacity than 4400 mAh or a form factor that does not match the original should look at other options.

The six-cell design provides 48 Wh of energy at 10.8 V, supporting typical office work, web browsing and video playback for several hours depending on system load.
