How do you actually take care of your MacBookPro's Battery ?

I'm using my MBP 15" like a desktop , with 85 Cycles and 96% health over 3months of usage..

Should i be concerned ? And how does Apple's Warranty cover this ?

Cause i bought the ACPP too..

Do clarify thanks.. I was told to charge to 100% - unplug charger - use to 10-20% then charge again.
