New battery seems poor quality
I just bought a new ifixit battery for may macbook and installed it accoring to the ifixit manual. When starting up after the install everything seems ok, but the new battery drains quickly. When using a batterytool (coconut battery) I saw that the design capacity is only 26% (see attached image). I assume this is not normal. What should I do to to get this fixed?
Is dit een goede vraag?
