replaced touchpad and battery. great! now my battery is not working...

first off, i work with smt electronics as my day job so the install wasn’t too out of the ordinary.

i replaced both the trackpad and the battery with brand new parts following the ifixit guide. everything was working fine for the past 2-3 days except for my battery randomly losing the charge once or twice when i closed the macbook and carried it somewhere (didn’t always happen). was using it this morning and i noticed the battery was stuck at 8%. unplugged the mag power, the computer completely shut off and now i see “condition: replace now” for my battery health.

any ideas? my immediate thought is that one of the wires connecting the battery to the logic board is making intermittent contact or is damaged.

well, update: i think the battery may be defective.

i turned on my computer last night and it took quite a long time to boot and things seemed very sluggish and laggy overall. i opened activity monitor and kernel_task was consistently using anywhere from 100-1400% cpu. i unplugged the battery from the socket, booted back up and things seemed back to normal. left the computer overnight and in the morning plugged the battery back in with same kernel_task results. after this i completely removed the battery and the computer is working well again. sending an email to ifixit to see about a replacement battery.

That would be my guess. Check the connection and test the battery and see if it has a short, it happens on new batteries every now and then. If the battery checks ok try cleaning the connections. Hope that helps
