Most likely you will need a new battery. However, if its under 5 months old, it might be under warranty. Call Acer support to find out.
In addition to that, follow the steps below to try and recalibrate your battery.

2How do I calibrate my battery?
Calibrating your battery helps get a proper reading on your current battery charge. If your battery is dying before the reported time given in Windows, it could be that you need to calibrate your battery.
Use the following steps to to re-calibrate the battery:
Turn the notebook or netbook off. Plug in your AC adapter.
Let the unit fully charge, until the battery LED turns off.
Turn on the computer and press the F8 key repeatedly when the first logo screen appears. In the Windows Advanced Startup menu, select Safe Mode and press the ENTER key. Unplug the unit and let the computer run on battery until it shuts down.
Note: The process to re-calibrate your battery can take several hours, depending on the battery lifetime and age, and the configuration of your system.
