I have the same problem, but with a MacBook Pro8,1 Early 2011
I replaced the already dead swollen battery for a new one from a seller in Amazon, it came with 78% charge, but it won't charge, I already troubleshoot for bad AC cords, which they work fine with other MacBooks, without any luck, tried resetting the SMC, force shutdown, disconnect battery and press the power button while no battery present, checked physically if the battery was not connected properly, so far nothing has worked, I even run Terminal with the next info:
-g batt
Now drawing from 'AC Power'
-InternalBattery-0 (id=4915299) 42%; AC attached; not charging present: true
Do you have any other suggestion that might help?
On the other hand, vents are always on a medium to high level with only one app run
ning, I also replaced RAM and upgrade to a SSD. Could any of these changes affect the battery charging?

I have the same problem and downloaded CoconutBattery and it shows all details about the battery with cycle count 1, Current charge 0 mAh, Full Charge Capacity 6803 mAh and Battery Temperature 83.9 F. The Battery info states Manufacturer Simplo, Manufacture date 2019-03-18, Age 451 days, Load Cycles 1, Serial D86638402UYHDWC4L, Power Adapter 86 watts and connected.
So, every thing is correct, battery sensing intact and charger connected. I have reset the SMC like 4-6 times. Hard to tell if it was actually reset since this Mac doesn’t have the chime (older Macs would chime twice when resetting the SMC). I’m puzzled and am going to contact iFixit again today as the only thing I can see that could be wrong is a faulty battery.
Other ideas are appreciated.

Please update me. I’d appreciate the help.

Leaving an update here. I contacted iFixit support about a replacement. I don't know what else can be done here.
Finding any information in the forums or else where has not been fruitful. I've only seen recommendations to reset smc and nvram which I've done.
I'll keep this thread updated with my results.

An update for anyone with the same issue.
I received a replacement from iFixit. It was prompt. The new battery came with a 40%’ish charge and the laptop worked as expected with the new battery.
Just need to return the old one now. As an fyi, I’m not under obligation to return. They did not need to authorize an additional charge in order to send me a new battery, and the return shipping is prepaid by them. They made it easy as could be.

Sounds good. I have a 3rd battery pack coming from the Amazon seller so will install it Sunday or Monday when I return. I’ve also ordered a USB-C power meter to see if the MB Pro is trying to charge in addition to the battery voltage for a charge. I do know with some certainty that the Simplo batch from March 2019 seems to be problematic. I did go to their site and submit a question but have not heard back from them.
