MacBook Pro repeatedly shutting down after battery replacement

I recently replaced the battery for my Mid-2012 MBP using the iFixit battery replacement kit and instructions. Everything booted up without a hitch, worked great for about 2 hours, and then shut down randomly.

I've been able to reboot using my magsafe charger, and then unplug and run off battery power. However, this only works for about 10 minutes before the computer acts as if the battery is suddenly disconnected and shuts down again.

Things I've already tried:

  • SMC reset
  • PRAM reset

Anyone have suggestions? Thanks in advance!

Weird. Is the computer getting really hot? Macs have several internal thermometers and if it gets too hot it will shut down. This can sometimes happen with non-OEM batteries although sometimes the non-OEM batteries are just as good if not better than the Apple batteries. The old MacBook Pros with removable batteries had absolutely awful reviews on the Apple website so I got a non-OEM and it was great.

It could be a Logic Board issue or a RAM problem which unfortunately is soldered onto the Logic Board with Retina MacBooks.

The only other thing I could recommend is backing up the MacBook, wiping it entirely, reinstalling the Mac OS, and seeing if the problem continues. If the problem is fixed, move your files back on.

But before anything else, try opening Console (command+spacebar and type in Console), select "system.log", and search for the word "shutdown". Maybe the logs will show us something.

This is happening to me too.

SMC reset seemed to fix mine though

Please download and run Coconut Battery, then post your results so we can get a better idea of what happening with your battery.

UPDATE

Thanks for posting. The battery has 0 cycles. Let it charge completely up then run it down all the way and then recharge. Is this an OEM battery?

Ok, will do, and thanks for the advice! And I used the battery provided in the iFixit kit. coconutBattery indicates that the manufacturer is Simplo.

Make sure it's only shutting down when on battery power and not when it's plugged into a MagSafe adapter.

Try reseating the battery connector. If it's still having issues when on battery power, then it sounds like something's wrong with the battery cells and they're unreliable. It doesn't happen often with new batteries but it does happen, I've seen then happen even with Apple's own batteries. I'd suggest asking for an exchange at that point.

Same issue here. Also MBP mid-2012. Did you manage to fix it?

Similar issue. Battery works good, MacBook runs several hours. But if it comes to lower percentage it suddenly shuts down instead of hibernating.

Currently the standard percentage shows 86%, but Battery Monitor shows 82%, which seems to be the right one. Can I somehow sync it to the system? I already did a SMC reset. And a calibration.

Same issue. My battery runs very well. It has 7381 mAh (original 6900 mAh) . But the Macbook Pro wont goes standby mode just before cut off the battery power. The battery consumes all its power and the machine suddenly loses its power. This error occured after battery replacement with this oem battery.

I am experiencing the same problem with my Mid-2012 MBP 13” A1278 after replacing battery with iFixit replacement. PRAM and SMC reset did not resolve the problem, only reverting back to the old battery did.
