On average, 6-cell Lithium-Ion batteries will last approximately two to three hours on a single charge. Unfortunately, exact battery run time and life span information is not available. Various factors, such as the temperature of the battery, the applications running on the notebook, any attached devices, the brightness of the display, and the notebook power management settings all determine the run time and life span of your battery. Also, the performance and charge times of Lithium-ion batteries decrease over time. There are suggested ways to help increase the run time and life span of your battery:
- Reduce the brightness of the screen to the minimum readable level
- Remove peripherals (External hard drives, CD-ROMs, Zip drives, PC cards, and other peripheral devices) when not in use; these devices can draw power from your battery even when they are not in active use
- Reduce the speed of your processor
- Turn off the Wireless On-Off button when it is not in use (If your notebook has one)
My battery for this laptop last anywhere from 2-4 hours, depending on how much stress I am putting on it, but a good 3hrs is average for this laptop.
I have had this computer about 2 weeks, and the battery seems to last around 5 hours on average....longer than the Dell computer I was previously using.
