    Hey everyone, first post here!

    I was wondering if this new 10 hour battery technology could be transported to the late 2009 models of the MBP. I figure since they have the same form factor it might be possible but I have no educated clue as to whether this is what determines that.

    Basically, when my battery needs to be replaced on my late 09' 13" MBP would I be given a 10 hour battery or the old 7 hour one?

    Be gentle on me! :)

    No. Its a combination of hardware changes not limited to just the battery.

    It's not just the battery...it's also the energy consumption. The new battery does hold slightly more watt-hours of power than the old ones, but we don't know whether it is larger or not than the old one. (While the exterior form factor may be the same, the internals may be slightly different.)

    But even if the battery compartments were identical, you wouldn't get 10 hours out of your old computer with a new battery, as the rest of the machine would still be the older components that are less power-efficient than the new ones.

    Plus, I think Apple would give you the older battery. :)
