Imho, batteries are nowadays designed so long (1000 cycles?), I think you don't really need to bother too much. The best advise, usually, is that you should let the battery get used from time to time. But no need to purposely do a full discharge and recharge.
Same advice for "VodkaPear". Do not perform full discharge and recharge of the battery religiously as advise by some others. Lithium battery on current technology are not this weak especially when it comes from Apple machines. They are pretty hardly and of good quality.
Like any consumables, they will deteriorate over time. Discharging them and charging them again wouldn't change anything except to tell the SMC which voltage is 100% and which is 0%. Generally brand new Lithium get a charging voltage at 4.2V and when depleted should not go below 3.0V. There is a cut off in the controller. The Nominal voltage of 3.7V after stabilisation.
Overtime the chemical construct of the battery will starts breaking down and the nominal voltage will drop. However for the sake of giving you proper remaining battery hours, the SMC inside will need to be updated. They should be updated when you are using it, it normally doesn't require a full discharge to know that.
Due to my recent encounter with escooters and it is using Lithium Ion batteries, I did some rather deep research into this matter to understand the difference between Ion and Polymer(used in Apple laptops), older other laptops are using Ions. How is it the need to balance charge between multiple packs of Lithium batteries and so forth. That's why it got me to understand better how it really works for this power packs.
Often discharge and recharge of the battery will only consume the cycles with little benefit to the end-user and definitely no benefit to the chemical process of the cells. Whether you like it or not, it will still deteriorate and will not whole as much charge and as long once the internal resistance build up over time. So muse use as much as you need, or stick with the AC mains to avoid using the battery. If you still want to use your model of laptop after AppleCare period, pay Apple service centre to service your battery and continue as long as possible. By then, you will be more concern with the age of your laptop rather than your battery.
