This particulare battery was manufactured in July 2016, therefore the sitting around may have been the cause. Then used it as normal & the full charge capacity settled in to whereabouts it should be with a brand new battery, just a few m Ah above the 6559 and its been great since.

Charged it again, removed it from the magsafe charger & let it sit & rest overnight, checked it again & now the battery reflected its full charge capacity and then some of over 7000 mAh & the battery now was just under half charged & NO SERVICE BATTERY notice. What I did was top off the charged, then did a discharge until the MacBook pro shut down, only took a fews hours of playing a video since it was really only half full. It also triggered the SERVICE BATTERY notification. "Not saying half charged" fully charged but only half the storage capacity. When the battery was first installed, it only showed half of the 6559 mAh full charge capacity.
