Is battery dead?

I have a MacBook Pro (2017) without Touch Bar (13inch). I plugged it in one day and it had the plug symbol on the battery. it showed the percentage but had the plug symbol.

When I unplugged it, the laptop turned off and I couldn't use it without it being plugged in.

An hour later, the battery was fine, it was fully charged and I was able to use it without it being plugged in.

I checked the battery health, and It was in good condition.

The same problem has happened again, but the laptop hasn't fixed itself this time and I have to use it whilst its plugged in. Ive done an SMC reset and it hasn't been resolved.

I bought the laptop in 2017, the battery was replaced in 2018. Is the battery fully dead?

MacBook Pro 13″, macOS 12.0

Did Apple replace the battery or did someone else?

Have you tried a SMC reset? The System Management Controller has battery management among its many duties. Please read these instruction fully before proceeding:

The T2 processor was not fitted to 2017 MacBook Pros, so you can ship that part.

Apple replaced the battery because they were recalling laptops with certain series numbers.

I've done an SMC reset and it didn't work.

I did a diagnostics and it said battery not detected.
