This replacement battery must be installed inside your laptop. This is a task most computer users can do themselves as the screws holding the bottom of the Tablet case simply need to be removed with a small Philips head screwdriver. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 1 year warranty.

You can expect about 4 - 7 hours of run time with this PA3884u-1BRS battery when new, depending on your energy use.
