So after liquid damage, my trackpad stopped working I ordered a replacement online and I am planning to change it, I’ve watched several tutorials, but I still have some questions Can I reuse the old battery after removing it (If it is still in perfect condition?)Should I apply a low voltage after the repair? my macbook pro doesn’t have a usb-c port *
Reusing the battery is iffy! In the process of removing it you will stress it. This stressing can damaged the internals. Just like hitting someone hard you won’t necessarily see the damage on the surface as your spleen ruptures! Best to replace it! The only system which requires a low voltage applied is the Retina MacBook 2015 Repair as well as the 2016 & 2017 systems. Make sure you haven’t confused yours with these.
