A2179 battery not charging after replacement

Replaced my A2179 macbook air battery as well as usb-c connectors. battery works, so I was able to get computer running again. However, it won't charge. Thought usb-c connector was not put in properly, BUT when attaching phone to computer through usb-c it will charge the phone - so it will work charging accessories, but not itself.


Tried reboot tricks, SMC reset, etc..because I have been trying to figure this out for so long I no longer have enough battery to reload macos, which I heard might be part of problem.

Any other ideas? Could it still just be the usbc connector isn't working fully?

If you put the old battery back in does it charge?

At the very beginning my initial instinct was that it was just the usb-c connection. It is a friend's daughter computer and noticed some external damage on that corner. So initially I only ordered a new usb-c connector and replaced it and nothing happened. Tried different cords, power bricks, etc.. so I assumed, at that point it was definitely the battery or the display (my a1709 display cable had to be replaced at one point)

To answer your question - I haven't put the old battery back in to see, but given I tried the old battery with the new usb-c board/connector I don't know if that would be it - i'm willing to try if that is your initial instinct?

The part I can't find online really is how/why the usb-c is allowing phones, airpods to charge from the macbook's battery. The flow of power going only out is odd to me.

Another note: even with the new usb-c connector, only one port works with regard to flow out.

I would like to follow this post. I too am having this issue.

does it autostart if you plug only usb-c cable to it?

yes it does, id assume because no screen is attached.

do you have multimeter and usb-c tester?

if yes: plug in charger, plug in battery. measure voltage between leftmost and rightmost pins. then repeat without the battery.

if charging circuit is functional, without battery there would be 6V pulse with 1 second interval. there also should be slightly fluctuating voltage on third and forth pins of the connector (first would be closest to fan connector). that would indicate device trying to ping battery.
