    I bought a refurbished Macbook Pro (specs in signature) a few days ago and firstly checked the number of cycles on the battery, and this number was at 13. Since then I've added 3 more cycles to the battery bringing the total to 16.

    My question is, how often in terms of time or number of cycles should I be calibrating my battery?

    You only need to calibrate the battery if you notice it going into deep sleep with, say, 10% charge remaining. This suggests your computer needs to re-establish the zero reference point so the reading is 0% or 1% charge remaining before entering deep sleep.

    Okay. I've been told in the past that every 3 - 6 months I should be calibrating batteries to get the most out of them. Guess not...

    You can do that to be sure.
    But to be honest, you dont have to do it very often.
