I've written about [http://www.ifixit.com/blog/2009/11/zen-and-the-art-of-battery-life/|maximizing physical battery life] in the past, but I'm curious what the most clever techniques you've come up with to reduce the number of cycles you put on your battery. Making each cycle last longer clearly has a huge impact.
Apple has a nice page up with tips for [http://www.apple.com/batteries/notebooks.html|notebooks], [http://www.apple.com/batteries/iPods.html|iPod], and the [http://www.apple.com/batteries/iPhone.html|iPhone]. What techniques work best for you?
My best tip? I found [http://www.bashflash.com/|BashFlash] a couple weeks ago, and it's made a HUGE difference in my battery life. My machine doesn't run nearly as hot, either.
