    Does anyone know if someone makes a screw/bolt/stick on battery for the 15 or 17 inch MBP. A long time ago they made external battery packs that you mounted to the bottom of of your laptop it did make it thicker but if you were out in the field it would run your laptop for a very long time.

    HyperMAC battery works but...

    I bought a HyperMAC battery. it works but...
    pro: compact
    charges up faster than I expected--seems to "charge up" faster than MacBook--also can be used to charge IPOD or Iphone--

    Cons: can't tell when it is 100% charged (only 75%)... LED lights similarly don't seem to be accurate at low charge
    . transformed runs hot.... don't leave it plugged in!
    service/sales support is non-existent.
