I've recalibrated my battery each month since purchasing my MacBook Pro to keep the battery as fresh as possible. Run the battery down till it goes to sleep, wait 5 hours and then recharge it to 100%. I understand that there is a circuit that tracks battery health for the System Profiler. Because I travel a lot and didn't want to be caught somewhere with a dead battery, I purchased a new one.

If I recalibrate a battery and then switch to the other battery, how does the circuit keep track of which battery is which? If I buy that Solid state drive in the store and migrate to it, will those settings be lost?
