PB 15" 'Heavy Duty' battery?

Hi,
I've been using my PB for the past 4 months now and I'm loving it! (Just a recent switch from Windows). The only thing that annoys me is the battery, does Apple make any long-lasting / Heavy Duty batteries? mine lasts for about 2:30hrs tho' compared to Centrino laptops 6hrs. Thanks

Apple only has one kind of battery per PB (right now anyway, but there are 3rd party batteries with increased (slightly) capacities. I've been eyeing the one from NewerTech for a little while now. The higher capacity one is the same price as the Apple battery.
