Problem with replacement battery (Empty battery screen when charged)

I recently installed a replacement battery for my MBP and though I’m getting much improved life there is a problem.

If I leave the computer overnight (lid open or shut) when I try to turn it on again it displays the empty battery screen, regardless of what charge remains in the battery. This morning, for example, it displayed the empty battery screen so I plugged in the charger and turned it on. There was 92% shown on the battery indicator and laptop worked quite happily without the charger until it shut down normally around 5%.

Should the battery voltage not be higher than 10V?

I don’t see anything in that app that isn’t shown below, but if you think it will help.

Let’s get a better view of things, install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see Adding images to an existing question

I think you'll find it easier than having the dig through what Apple gives you for an output which is very chaotic!

Have you solved this problem? How?

No, I never did manage to solve the problem.

From what I see the battery is in good shape, the charger is charging it. I don’t see a battery or charging issue here.

More likely you have something running in background which is draining your battery. I would check Activity Monitor to see what’s happening. You could also try booting up on a clean OS installed external drive to isolate things as well (which I often do to check things like this)

The other possibility is corrosion on the logic board is slowly discharging your battery. Did you have a liquid spill at some point or do you tend to clean your system spraying it with a cleaner and then wiping it off or use disposable wet naps, these both tend to allow moisture into your system.

Follow this guide MacBook Pro 15" Retina Display Mid 2015 Logic Board Replacement to remove the logic board to inspect it carefully for any signs of corrosion or wetness if you suspect corrosion.

I think I can safely discount the battery discharging for one reason or another, because the battery has the same level of charge as it did when I put the computer to sleep.

The problem is that the empty battery screen is being shown when it shouldn't, even when the battery is practically full.

@jonbob - SMC logic tells the OS what the batteries status is. Did you have a liquid spill at some point?

The SMC logic is on the backside of the logic board. Its time to open things up. Take some nice clear sharp tight shots of your logic bard and post the pics here for us to see Adding images to an existing question

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

It's never been wet, and I'm not about to disassemble the computer without a good reason.

Please re-read the question; the battery is not empty. If the current capacity was merely being read incorrectly the computer wouldn't be able to run for hours after being plugged in for less than ten seconds.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@jonbob - Then its time to find a local expert who can help you. There is only so much we can offer without enough data to work off of.

I have exactly the same problem.

First thought:

I think the problem is in a non-original battery.

Second thought:

Monterey operating system.

How's your Mac OS?

When resetting smc, the laptop turns on without the power supply, but the problem returns again after being idle =(

@wkbrkhjg4ndxzzp - Let’s focus in on your logic

1 - 3rd party batteries: If you installed CoconutBattery you would see if the battery was the issue or if the charging logic was the real issue. Some battery makers salvage the microcontroller chips from used batteries and fail to reset them so the battery input to the charging logic is faulty, just looking at the batteries date can identify this. Otherwise the state of charge and it’s charging current offer you enough of a clue if the charging logic is defective which is often the issue as people try using knockoff chargers which damage the comparator logic burning the resistors, so once damaged you need them replaced. The age of the battery often is reflected within its temp while charging as well as it’s cycle count.

2 - macOS issues: Not likely! I would aim the issue at the systems SMC firmware, but that is very unlikely as well.

So the bottomline here one needs to methodically diagnose the issues at hand. CoconutBattery offers what you need so how about diagnosing your problem In a fresh question as it’s clear jonbob was not willing to follow a proven process.
