Does the issue go away with the original battery installed? If multiple batteries are behaving in the same way, the issue is most likely not with either battery, however if you’d like to try another replacement battery, you can contact iFixit’s Customer Support and provide them with the order number and the same details provided here. Your issue could be a caused by a few other components, namely the logic board, MagSafe board, or could even be a software conflict. To rule out software as a cause, you can try performing these steps to see if the issue goes away: # [guide|9314|Repair and verify Disk Permissions] # If you are running MacOS El Capitan or newer (MacOS 10.11+), please follow [guide|52680|this guide] instead of Step 1 # [[How to reset NVRAM and PRAM on a Mac|Reset the NVRAM/PRAM]] # [[How to reset the SMC on a Mac|Reset the SMC]] Otherwise, if the issue persists after performing these steps, then the issue could very well be other hardware. I hope this helps!
