Data showed by Coconut battery are too good to be true, no battery stays perfect after 122 charge cycles, even above design capacity in this case. The two possible options are a faulty SMC circuitry or a faulty battery logic. Unless you are willing to test component by component all SMC charging related parts the only way to know what’s wrong of the two is to find an alternative battery.

One could just try a known good battery to isolate out if the battery is reporting correctly. I've encountered a few batts that just lie to SMC

Who's battery did you put in? Also why did you also replace the logic board?

The original logic board failed so it had to be changed, don’t kniw the brand if the battery because it was installed from a third party store, what i find strange is that the full charge capacity is greater then the designed capacity. Isn’t that over charging ?

Lets pop the bottom cover off and disconnect the battery. press and hold the power button for a good minute. Then plug in the MagSafe charger the system should spontaneously start check the CoconutBattery again snap another pic and also give us the batteries info.
