im at 133 cycles with 33% battery health left on my MBP. gets about 40-50 min per full charge. today my computer shutoff while unplugged even though it said 40% charge remaining. i calibrated my battery last week.
I dont know how i didnt properly maintained my battery... I used my laptop periodically, charged it, never had it plugged in for an extensively long time.
these batteries simply arent that good. check out the reviews on the apple store about these batteries. not getting much for $129
 
I'm at 71% with 303 cycles on the batter for my macbook. I have noticed that my battery life fluctuates alot one day it will be at 82% the next day it will be 70% I dont know why it does that. I've done the calibration steps that apple says to do and everything...Anyways to answer your question, NO that is not normal!
 
I'm 97% after 558 load cycles, so that seems really low. Should be at least 80%. How often do you calibrate?
