HELP - New battery is not working!

Hi,

URGENT question…. I followed your instructions for replacing the battery. I have a MacBook Pro Retina 15” Mid 2014, Model A1398, laptop, and when I replaced the battery (correct battery (A1494 model)) for this Macbook Pro model - the laptop recognised the installed battery but would not charge it or work without power cord attached. When I followed the process to reinsert the original battery (which had a enough life in it to test the system with it back in) also came up with the same error. Have Apple put in a trip wire code in to stop us replacing batteries in newer glued in battery MacBook models at a hardware/software level???

Note on remedies attempted:

1. Restarting the Macbook. Shutting down, waiting 10 minutes, plus holding down certain keys during shutdown/startup procedures as per some instructions - no change or success.

2. Resetting SMC, PRAM and NVRAM - no change or success.

Have screen shots of the system report if needed.

Can you help to get my Macbook to work on battery again?

Same problem. Installed new ifixit battery to my macbook pro retina 15 mid 2014. Powered up laptop with charger attached. Light went to orange but info said not charging. Tried SMC, charger briefly went green then back to orange, same info, not charging. My mac is 2.5 version, 11.2. Battery dropped 1 % every few mins, tried doing latest update, after 15 mins charge suddenly dropped to 7%! Battery fitted is a1494 11.26v 95 wh. Wrong battery?

P.S. I also get low memory warning on the screen which I did not get before the battery change. I did a hard shutdown before losing all battery so the update was aborted.

If I remember correctly, Apple has it set up where they are the only ones that can reset the battery life information.
