Accidentally bought and installed wrong battery
I was unaware that the same model number could be for different years, and ordered the a1534 early 2015 retina battery and installed it into my a1534 early 2016 retina laptop. It has been working fine for a month, but now it temporarily fails to charge and gives large estimated times to be fully charged. The battery's seem to have different model numbers for each, so I imagine they're not completely compatible? Should I just take the L and order the right battery or is the laptop ruined?
