Replacement Battery Doesn't Charge

Macbook Pro 15" (mid 2017 touch bar) A1707.

I replaced the original apple battery with a replacement battery that I purchased from Ifixit and it wasn't charging. It booted and worked when plugged in but the battery wasn't recognized. I did everything including SMC and nvram Reset to start the calibration process but it still didn't charge or work when unplugged.

Ifixit sent me a second replacement battery. I just replaced it and did all the same resets again. The new battery, once again, does not charge. I'm very frustrated because this is the second battery that doesn't charge and I did not make any mistakes during the replacement process.

Is there anything I can do to get this laptop to recognize the new battery? Please help, anyone! Dan, please!

During my first repair I also replaced the two fans, speakers and thermal paste and they all work wonderfully. Speakers blasting like new (literally), fan speeds down and silent, temps down more than 30 degrees.

The only issue was the battery. The new battery has "A1820" written on it which, as far as I can tell, is the right battery for the laptop.

Hi

Sorry but I’m not @danj ,I’m sure he will be here soon though we just need to wait for the time zones to do their thing

If ifixit has sent you 2 battery’s that are doing the same thing that’s quite rare

Have you tried the original battery to see if the behaviour continues?

Also can you download this amazing app called coconut battery(linked below)so we can see what the battery is doing:-)

Also once you have checked it out can you post a photo of the results using this amazing guide!

Just added the screenshot. Is it a calibration issue or could this battery be faulty too? Thanks for your suggestions!

@themacto

It could really be both

Il have a good look at the photos and see if I see anything strange until @danj has a look:-)

@themacto

Good Morning! @themacto and @hellomacos

Well, it does look like a bad battery, but I'm thinking the BMU cable is damaged or not fully seated

Sadly this cable is part of the battery assembly, you made need another battery ;-{

Thank you for your response!

I've been extra careful with that cable, wasn't pinched or bent at all.

I guess I'll ask Ifixit for a third battery and hope that it isn't faulty this time. :/
