After my horrible experience with iFixit battery, I decided to try another battery from Macsales OWC, The battery is called NewerTech 95W NuPower, and this specific one is for 15-inch MacBook Pro with Retina Display (Late 2013 to Mid 2015). This battery is cheaper than the one I bought from iFixit by $20, so it is worth trying it out. It turns out that this battery is really amazing and I don’t face any of iFixit battery issue where the battery read the actual battery percentage and there is no sudden drops from 80% or 70% to %7. Also I no longer face losing the charge when closing the lid. This battery hold the charge for a very long time, and so far it is equivalent to the original Macbook battery when I first bought the laptop.
I am very happy for Macsales OWC, because they always sell high quality products and I have been buying their ssd and ram for Macbook Pro for a very long time.
