Replacement battery is dead

Block Image

I replaced the battery in my late 2013 15" MacBook Pro a few months ago, worked fine until this morning. Suddenly the battery is completely dead as in nowhere to be found. The only way to get my macbook to work is by plugging it in, unplugging immediately turns it off.

Thanks, Dan. Interestingly it can't even find and read the battery:

Please post an image of your results when you click the "Battery info" tab when using Coconut Battery.

Thanks for your answer, and yes, I did. It worked very well until this morning. I opened up my computer to see if the cable connection between battery and logic board was loose. Unplugged and plugged it in again. No change.

Sorry your battery has failed! The micro controller logic is bad, Which is why the info is missing.

You'll need to get a replacement battery. Contact the seller to see what they will do for you.

Thanks Dan, I already contacted iFixit, they're sending me a replacement battery. I was just worried about something being wrong with my logic board or so, since I never had a battery fail like that. My old one (the one I initially replaced) just got worse and worse in holding charges and also was really swollen.
