Battery stuck at 1% after fully drained, will not charge
My MacBook Pro 2018 battery seems to have died last Friday night. After attempting to charge the battery for a while, I turned it back on and noticed the battery was still at 1%. The only way the laptop will stay on is if it is connected to a sufficient power supply. The battery tab says the current power source is the power adapter and the battery is not charging.
I took it to the Apple Store and they ran a diagnostic test that sent the info to their iPad. They determined the battery is not connected and few other errors like the SMC sensor, which might be from the battery issue.
There is no X over the battery and when I open coconutBattery, it shows the battery information. One thing I notice is that the cycle count bounces from 25 to 0 and back to 25 occasionally. I am confused at how coconutBattery can show a battery connected if the Apple Store test said no battery connected. Is there any fix for this or is a new battery the first step in resolving this issue? Could this be something more serious like the logic board?
I have tried the following troubleshooting steps:
-Left on charger over night while shutdown
-SMC reset
-PRAM reset
-Shift+Control+Option+Power button for 10 seconds
-Inspected the battery connections
-Disconnected the battery and connected it again
-Disconnected the battery, pressed the power button for 10 seconds to drain caps, then connected the battery.

It can sound like a bad battery that needs to be changed. Assuming you have been using the macbook since 2018 or even 2020 there should be more than 25 cycles on the battery. For example on my own lenovo laptop the battery information through lenovo vantage says 488 cycles. Something that would be more in line with a laptop of that age.

I am suspicious about the cycle count considering the age of the battery is showing it's from 2021. I have only had the laptop for a little over a month, it is a company laptop and they unfortunately bought the computer refurbished. I am not sure if the battery was replaced during the refurbishment and whether that battery was old stock.
