Only original battery work , not New ifixit one.

Hello,

First you Can sée this post that I made a few days ago.

Problem After replacement battery with ifixit kit. Notcharging at all

I wanted to change the battery of my Mac because my original one was decharging a bit Quick. So i bought an ifixit one. Nothing work. When i put the New battery my computer was just doing a bootloop.

So i decide to replace it with my older battery , and everything work back as Before. So i contact ifixit to send me a New battery , thinking they have send me a Bad one.

Yesterday , i réceive a New battery from ifixit and same problem. I put it and bootloop, so i plug it back again my original battery , and it work with it….

I try :

• Smc reset
• Nrvam reset
• Soft reset
• Check with command s error of disk

So what is blocking the charge of the New battery ? Could it be afps ?

When its plug the magsafe stay orange with new battery . But work properly with original one ..

Could it be again a problem of the battery itself ? But i already réceive two from ifixit.

Please help me , because i really dont understand why its working with my older one and not thé New that I bought.

I was thinking to power supply the New battery manually , but i am not a professional and i am scared to do that

Thanks you in advance…
