    Heyo :)

    Does anyone here use those Universal External Laptop batteries? (They plug into the charge slot of the laptop)

    Ive seen different models, from sleek 4500mAh capacity external batteries, to those big pad like 7000mAh externals.

    Ive also seen Big bulky 180-370WH Battery banks that are supposed to work with laptops too...

    Any experiences with these products? ( http://www.batteryspace.com/) ( http://batteriesamerica.com/) Advantages as opposed to buying original batteries (I can think of 2 at the moment... no more swapping of batteries, and you can recharge the extra pack while using your laptop at the same time)

    Erhhh... Brian? What the hell do you mean by...

    "It's reasonable to expect more optimal conditions to yield over 6 hours with a low voltage machine."

    ???

    If you don't have the screen on full brightness, etc, and if your laptop's voltage is less than 16v, the battery will last longer because the computer will require less power.

    Uhm... No. The input of your notebook has nothing to do with consumed power in a first approach. In a second approach, a lower voltage notebook will even be less efficient.

    I believe in several places in the article 'volt' should have been 'watts'. About the specific quote, either he meant a low wattage notebook in general or a notebook that uses an Ultra Low Voltage CPU (which in turn would mean a lower wattage notebook).

    I was actually thinking of LV or ULV... so they don't use lower voltage?? Then... why are they called "ultra low voltage"?

    Yes, the ULV processor takes less power than standard CPUs. Also turning down brightness, disabling wireless and such will get nice returns with this APC unit.

    Wow! very nice, I think I'll look into buying one of those things for myself. What is the maximum wattage of this thing? 6 hours is a lot!! Mine consumes about 25W per hour.

    the APC looks like 68WH or somewhere near that area...

    I was looking around the net for something similar... There's the NBMATE-118 (118 WH) looks pretty good... and its under $150.

    Will look around some more...

    I'd encourage you to go wtih a trusted name, as power is one thing not to mess with when it comes to your machines.

    Good point... I might get one of these myself, since I killed the battery charging mechanism on my baby :(

    whoa there. a low voltage notebook would be even less efficient?
    how does running the same clock speed at a lower voltage decrease efficiency?
