What is the best way to maximize Lithium Ion battery life in laptop

Morning Larry.

Lithium Ion batteries don't have a memory, so several partial discharge/
recharge cycles are better than a complete discharge. Also, if you are
going to leave it plugged into AC, it's better to remove the battery as
heat is a problem.
