This machine's labeling boasts a 45-watt-hour battery. Acer has said that the battery should last you around 12 hours, but reports say that it will give you around 7 - 8 hours of use. Given the fact that this device is primarily targeted to students, this is a reasonable run time.

On this model, there are no screws that lock the battery in place. Other than the cable itself, the only thing that's holding the battery in place is some anti-static tape. This does make swapping out the battery a bit quicker, simply because we don't have to worry about replacing any screws or removing any adhesive from the battery.
