Question about Acer Aspire 4720 Notebook
Laptop battery notification is not accurate but approximate. The remaining battery usage is calculated approximately and then notified to the user. If your battery's life is more than a year, then the calculation goes on decreasing. It cannot be rectified unless you go for a new battery. But still you can tweak the battery life by,
1. Switch of the wireless adaptor when not in use.
2. Decrease the screen brightness.
3. Configure your power plan in control panel to minimal power usage mode while on battery.
4. The notification limit for battery low can be custom configured in the control panel. set it to 30 % and this will prevent your laptop to dye without power as your battery power drains faster below 31%
I hope this is helpful to understand the logic behind this.

Testimonial: "thanx. does putting it in a freezer for some time help in any way?"
Usually this means the battery is starting to fail. The battery is giving the computer incorrect information which is what you are seeing. Usually this will get progressivly worse until it wont work at all. I see many batteries get to the point where they will go from 0% charged to 100% in a few minutes, but they dont hold more than a minute charge. Batteries fail often unfortunately.
