My Macbook Air 13" with battery A1405 is very low capacity (<1000 mAh) and I have bought a new battery A1377 but it reduce the performance. I wonder if I can change the battery cell from A1377 to A1405? Is it possible, safe etc? Is it increase the performance of my Macbook Air like an original new battery A1405.
Unfortunately you can only change the battery for a macbook air with a “like for like” … meaning only a battery with the same part number will fit … the A1405 is made for the newer Macbook air and will simply not line up with your macbook air :(
