Best practices for preserving Lithium-Ion battery life?

Ever wonder how you could preserve the usable life of your laptop or Blackberry battery?

Is it better to drain completely before recharging or is it best to charge the battery for a short amount daily as RIM suggests for the Blackberry batteries?

According to the Battery University, which was linked to on BBHub.com a few days ago, the best thing to do is indeed charge your Lithium-Ion batteries regularly. Apparently letting them get fully discharged actually decreases the life of your battery.

BBHub asked folks for feedback on what they thought of the situation, but hasn't received any comments yet.

I've found other sites that suggested the same thing, but still not sure. I'm just not familiar enough with battery chemistry/engineering to understand why Lithium-Ion batteries might behave differently than Ni-MH and Ni-CD rechargeable batteries which DO last longer if discharged fully before recharging.

So if any experts in the field of batteries reads this post, please enlighten all of us on how to keep our Lithium-Ion batteries going strong for as long as possible. Some background on why they are different from Ni-MH and Ni-CD batteries would also be appreciated.
