Title: Real world conditions, maybe barely watch a 2 hour movie...
Review: The battery is indistinguishable from the OEM battery it replaces. My old battery was close to 400 charge cycles and would last me maybe 20 minutes on a full charge. The new battery, after a couple of full discharge/full charge conditioning cycles typically gets me a little less than 2 hours to the low charge warning. If one is willing to reduce screen brightness and switch the processor to its energy saving mode, I know the battery would last longer. However, running the processor on energy saving mode also reduces performance, and I noticed that YouTube videos were jerky in this mode. So, in a real world situation, don't expect hours and hours of use out of a charge. I'm only slightly disappointed, as I'm fairly certain that my real world experience with this battery is not far off from most other battery choices out there for the 17" Aluminum Powerbook. That's alot of real estate to light up!
