Why is my battery so weak - Inspiron E1505

I just received my new Inspiron E1505 laptop a few days ago(thank you to all the people who helped me with the config) and I'm noticing that my battery which is a 85 WHr 9-cell Lithium Ion Primary Battery , I check it just to make sure, seems weak. At 100% it only last a maximum 3hr and 5 min, isn't this kind of weak. I check on my dads old laptop which is about a 4 years old 600m and the battery life is about 30 min's longer and it's only 53 WHr 6-cell Lithium Ion Primary Batter (granted the battery is slightly newer then the laptop because it was bought about a year and a half ago). Is there a problem with my battery or is it my system config?

    Some things to check:
     
    In your power settings (start -> Control Panel -> Power) make sure you're set to mobile/laptop.  Make sure you turn off bluetooth or wireless if you're not using them.  If you have one of the ATI video card options, make sure PowerPlay is enabled (display properties, advanced properties, open Catalyst Control Center, go to the PowerPlay functions, make sure the checkbox is enabled and the "battery" modes are set for battery life and not performance)
     
    The next question I would have to ask is: what were you doing for those three hours of battery life?
     
    I too have an Inspiron E1505 with the following equipment:
    • T2300 Core Duo 1.66ghz
    • 2GB DDR2 667mhz ram
    • ATI x1300 64mb video card
    • 8x DVD+/- RW
    • 80GB SATA 5400RPM drive
    • Intel A/B/G wireless
    • Dell 350 Bluetooth
    • 85whr battery
    So here's some examples of battery life that I've picked up while doing certain tasks:
    • Working in MS Word - Bluetooth and wireless off, screen brightness at half, power settings at "mobile" and powerplay turned on...   About six and a half hours of life
    • Surfing the web - Bluetooth off, wireless on, screen brightness at 3/4, power settings at "mobile" and powerplay turned on...  About five hours of life
    • Playing video games...  Bluetooth off, wireless off, screen brightness at full, power settings at "always on" , speakers at about half volume and power play turned off... About four hours.

    It totally depends on what you're doing and what settings you're using on the laptop as to how long your battery will live.  Perhaps now you can get some ideas of things to test, and maybe give us some more details on how you're using the laptop when the battery goes flat...

    Thanks for the tips I'm trying them as I type.
     
    What was the most amount of time that you were able to have using your settings?
     
     My specs are pretty close to yours except 100GB HD and 256mb ati.
    I hope this works work although my power play setting were already at he lowest. I haven't seen a change yet but I'll wait bit before i ask for more help.

    I believe that a new battery needs a few discharge / recharge cycles to reach its full capacity.
