Ifixit replacement battery 98% new, 95% after one week?
So my Macbook Pro battery was going completely dead under load at 65% when I opened FCPX, just loading the program drew too much power, also Apple batt indicated “service battery”. Bought the ifixit battery replacement kit for $110, spent the 3 hours replacing the battery, and did the calibration process. Charge up to green LED, contoinue charging 2 more hours, remove charger, turn on, let it run down on its own, then leave to shut down, then 5 hours, then charge back to full. Capacity read only 98% after that initial calibration. Computer would get to around 50%, then instant drop to 7%. That is like 4000mah indicated on Coconut down to 700mah instantly. After it completed that 1st calibration, a few days passed, I ran a 2nd calibration, and the results were the same, 98% capacity, and that weird drop from 50ish% down to 7%. Few more days pass, it’s this morning, I am charged up +2hrs, unplugged, and in the proces of running down the battery again…only that initial chargup coconut battery says the ifixit battery only has 95% (8300mah of 8755mah design) capacity with 7 charges. I bought this new battery to sell my Macbook, but how will a buyer respond when I tell them it has a new battery but they see 95% full capacity and that drop to 7%. Is this battery bad? I would hate to have to return and redo a 3 hour replacement process again. I should mention I also reset the SMC a few days ago hoping that would clear whatever was causing the battery reading issues, but no dice. :(
