  • Do not leave batteries exposed to high temperatures for extended periods. Prolonged exposure to heat (for example, inside a hot car) will accelerate the deterioration of Li-Ion cells.
    Remove the battery if the notebook will be stored (turned off and not plugged into AC power) for more than 2 weeks.
    Remove the battery if the notebook will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks.
    Store Li-Ion batteries between 20°C and 25°C (68°F and 77°F) with 30% to 50% charge.

    Reduce the brightness of the screen to the minimum readable level. Use the function keys on the top of your keyboard to adjust the brightness.
    Remove peripherals when not in use. External hard drives, CD-ROMs, Zip drives, PC cards, and other peripheral devices can draw power from your battery even when they are not in active use. Disconnect them when you have finished using them.

  • Turn off the Wireless On-Off button when it is not in use. If your notebook has one, press the Wireless On-Off button so that the light turns off.
    Make sure your battery gives the power you need, when you need it. Power Options in your Control Panel allow you to adjust the power management features of your notebook PC.

    Short discharges and recharges do not fully synchronize the battery's fuel gauge with the battery's state-of-charge. This can result in the amount of power available in one cycle being less than expected or the battery meter being inaccurate.

    Under normal usage, batteries should be calibrated a minimum of once every 3 months. Use the following links for more information on calibrating your battery

  • Depending on what your doing and the size of the battery it should last longer than that. I think most laptop batteries are 4-, 6-, or 9-cells. The more cells you have, the longer it will last, theoretically.

    I would suggest googling "laptop battery life" or something similar to see if you can find what you're looking for.

  • The thing is, it depends on how your charging it as well (which I am guessing is the problem). Most people aren't even aware. Did you read that part?

    Short discharges and recharges do not fully synchronize the battery's fuel gauge with the battery's state-of-charge. This can result in the amount of power available in one cycle being less than expected or the battery meter being inaccurate.

    Good luck!
