Chosen Solution

Just replaced the battery in my MacbookPro A1398 (Mid 2012 Retina). The new battery initially showed 105% health, but after “calibration” as suggested (drain till shutdown and charge 100% again), it only shows 90% health - in fact it kind oscillates between 88-91%. Again this is health, not max charge %%. The cycle count is still 0 after calibration. Is this normal ? Or is it a sign of a problem replacement battery ?
