Answer to "New replacement battery quickly drops to 7% and stays there, why?"Same issue but with NewerTech NuPower battery for my early 2011 15” MBP. From a full charge, my battery drains about 1% per minute down to 5% or 7%, then it holds there for a long, long time. At that time, however, my machine will often become sluggish, so I wonder whether peak current is dipping below a critical threshold. I am now on cycle 59 and still have this same issue. I had the battery replaced; same thing. Design Capacity is 7200 mAh but my Full Charge Capacity is 7206 mAh. A few months ago full capacity was 7191 mAh, so somehow it’s gone up… Anyway, I seem to remember getting more accurate performance once the Full Charge Capacity dropped below the Design Capacity threshold, but I’ll have to wait a bit longer to confirm that. Like the other poster, I would gladly pay good money for a OE Apple battery, but alas… my machine is vintage.
