    Hey all - I noticed Dell wants a ridiculous $299 for the 9-cell battery upgrade for my Studio 17. Is there a reliable place that I can purchase quality notebook batteries? Is there such a thing as a universal notebook battery, or am I stuck with a model-specific replacement? I appreciate the insight.

    I wouldn't trust anything not made by Dell. Sorry to give you the brutal truth, but non-OEM batteries are not very well tested and they are guessing as to what the laptop really needs. And they don't have Dell's battery test methods, which leads to further worry.

    Check out the Battery Guide for more, but I recommend forking out the $299 if you really need the battery.

    open up the battery case..

    find the model number of the batteries..

    search for the same type but higher amperage..

    order them online for ~$50..

    solder them in yourself.

    Thanks, Greg. I definitely want quality and will spend the money if that's my only option. I figured this would be the answer, which is why I also don't buy OEM ink for printers.

    Not recommended.

    Oh, and you won't want higher amperage cells...that only means they can output more, they don't have more juice in them. You would want higher capacity (WHr) cells.

    First off, not trying to say rebuilding your battery is a good idea. I was just searching this site for information on mine and saw this post.

    Your first statement is absolutely wrong. Your second statement is correct.
    Batteries are rated in amp (A) hours or milliamp (mA) hours

    These batteries are 11.1 v

    11.1 volts at (1650 x 6) 9900 mAH = 109.89 WHr.
    11.1 x 9.9 = 109.89
    Watts law. Volts x amps = watts
    Also ohms law V=I/R at a given voltage and resistance you will get a specific current
