"Adhesive on new Ifixit battery doesn’t stick. Old stock?" için yanıtI’m actually having the exact same issue with my Late 2013. New iFixit battery but shows MFG date of Novmber 2019, and it’s July. though I put it in a while back It only stayed adhered for maybe a couple of days and that was it, now it flops all over. Going to try some tape and maybe something to shim it up from the bottom case just to keep it from rattling. Rather annoying, and bottom case was clean as could be with alcohol and the adhesive remover that was used to remove the battery. Or perhaps the ones from 2019 had some adhesive issues? This thread is from the exact same timeframe as my battery’s date of manufacture.
