I know when I was interested in a similar question several months ago, the advice I found was that laptop batteries like to stay at a higher charge level. Depleting the charge and allowing the cells to remain empty should damage the battery's capacity.

Lithium-Ion batteries really dislike being used to their limits, e.g. charging to 100% and discharging to 0%. They also dislike heat. Those should kill your battery fairly quickly.
(Note that it's measured using Apple's diagnostic tools, not using the value displayed in the System Report).
Assuming, hypothetically, that some selfish person were happy to get a new battery paid by Apple for their expensive laptop as it approaches the end of the AppleCare contract, but the diagnostic pegs it at over 80% - would it be possible to push it under 80% over a few months? How? (Not a question most articles on laptop batteries address, for some reason...)
