And also be sure to calibrate your battery at least once a month, by calibrate I mean follow the procedure I outlined in my original message of totally exhausting the battery so in other words, if you have a Macbook or whatever then take it off power from time-to-time. When I had my Ibook, I often found the easiest way to go calibrating batteries was to disconnect the power and listen to talking books whilst in bed, then I'd fall asleep and the computer would stop working when the battery became exhausted, ready for me to reconnect the power, recharge the battery and continue working the next morning.

I've had web sites with some kind of CPU intensive flash ads suck my batteries down. Burning CDs, compressing Audio and other CPU intensive processing will also shorten battery life quite a bit. If you don't need the screen then be sure it's dimmed all the way down which turns off the backlighting. I've hit 5-6 hours on a battery with the screen off and low CPU applications like text editing for taking notes at conferences.

Indeed, but if settings are set to to off or nill then I'm lead to believe that a battery should last about 3.5-4 hours, of course it will last longer if energy saving features are turned on, brightness reduced etc.

Battery life estimation is not an exact science. It's quite common for battery times to go up and down a bit depending on exactly what your computer is doing internally at any given moment, and this is not at all exclusive to macs.
