Batteries are consumable items, so it's expected they will deplete after a while. If you have AppleCare coverage and your battery health declines below 80% before 1000 cycles, Apple may replace it free if they determine it's defective. Otherwise, replace it at your own expense when it no longer holds sufficient charge to meet your needs. The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration
like the removable batteries in older Apple notebooks.
