Battery control board dead?

I used this iFixit kit last March on my wife's early 2015 MacBook pro:
IF123-054-5, the "MacBook Pro 13" Retina (Early 2015) Battery"

The repair went fine, and the MacBook worked great afterward until this month. Without warning it began to act as though the battery was not connected. The system report says it has no capacity and no cycles count:

CoconutBattery also can't get any information:

I found another thread from last year: someone with the same laptop used the same kit, and encountered the same issue. He received a warranty replacement, which worked but the replacement ultimately failed with the same issue again:
Battery stopped working after a couple of weeks after replacement

Has anyone else had any luck troubleshooting this issue? I have an email in to customer service -- I assume it's a bad controller on the battery and I'll need a replacement -- but won't hear back from them until Tuesday at the earliest.

@russww - Sadly, the micro-controller has failed within this battery.

One of the problems many have faced with COVID and the Ukrainian war is the tight supply of microelectronics.

Even the auto industry has had serious supply and quality issues. Surprisingly, this micro-controller is used in many laptops and there are lots of reports of failures within the industry.

For comparison we had a simulator issue quite a few years ago when the capacitor electrolyte chemistry was messed up with a bunch of capacitor makers Capacitor Plague

So you will need to contact the iFixit Store to get a replacement.

Thanks! I'll try to get the warranty replacement and cross my fingers.

I remember the leaky capacitor era! Not fondly! Thank you.
