    I want to somehow attach an extra battery on a modified laptop, is this even possible and has it been done?

    One of my earliest ideas was for a modular laptop with that very capacity. I've alway believed the optical drive should be removable with that in mind: extra battery, HD, optical drive etc.

    If I'm not mistaken Dell was the leader in that area. But I can only remember brief segment of that idea actually being used.

    I'm wishing for the day when someone will offer these caddies as standard plug-in and go: If you need an optical drive today. Plug that in. If you need extra battery, plug that one in. If you need an extra HD?

    I wondered about putting one in a spare HD bay a while back too. Depending on how SATA is powered, you might just be able to feed the power back through the MB, though I doubt it would that simple.

    Older laptops used to have this option.
    I remember several dell's I had where I purchased the expanded battery and all it took was removing one screw to pop out the floppy or CD drive and then pop the extra battery in.

    They got rid of them as battery technology improved and since most people want thin, light laptops... (the old ones were thick, heavy and even with the extra battery you were lucky to get 2hours worth of run time total)


    NOW, I can purchase an extra/external battery to go with my HP 8540w.
    It plugs in the bottom where I would normally plug in my dock.
    It adds about 1-3hr of battery run time on top of the ~2hrs I get from the built in battery.

    It might be worth checking out the HP Envy slice as well.

    Many toughbooks since the M series have had this ( late 1990's)

    I know for certain the CF-28, 29, 30, and 31 all can swap the DVD drive for the media bay battery. the older CF and M series could as well. its pretty common for business class and industrial laptops to have extra batteries internal or clipped on externally.

    my X220 has a battery slice giving me an extra 10 hours. and the slice for my 8740W gives me an extra 3-5

    I'm prepping an E751 for a customer tomorrow. It has a modular bay for optical drive, second battery or second hard disk drive, spec sheet claims 10 hours with one battery and 17 hours with two.

    The laptop itself felt pretty good too.
