MBP crashes immediately when unplugging power cable
Mid 2010 17" MacBook Pro crashes immediately (or sometimes up to 1 minute or so) after unplugging the MagSafe cable. I have a new battery that is recognized by the Mac (and the Coconut Battery app) and is charging properly. I have reset the SMC and PRAM multiple times and reformatted the SSD and reinstalled High Sierra from a USB drive. I even tried with a clean install of Ubuntu 16.04, with the same issue.
The strange thing is that it works unplugged while I start MacOS in Safe Mode, and it runs the battery all the way down to 1 or 0 % (for multiple hours). I can start up the Mac and remove the cable and then leave it unplugged at the log in screen without it shutting down, but when I press enter and it it starts to load the Mac shuts down.
I should mention that my original battery had a Service Battery status for many years and only ran for 15 or 20 minutes maximum and that is why I replaced it. My first replacement battery wasn't recognized at all and when I reinstalled the original battery it changed to the Replace Now status and the charger was green all the time. That battery also shut down the Mac immediately when unplugging the charger cable. I used the old battery for a few months and the last week the Mac started to shut down sometimes even with the charger plugged in. So I removed the battery and ran the Mac without a battery and ordered the current one.
Edit: Added CoconutBattery images. Will try to fix the log files soon.
Edit2: Added the system log: system
Edit3: Report from EtreCheck: EtreCheck test report
Update (03/20/2018)
I also found a kernel-shutdown.log file in the same folder (but it is from yesterday) which reads:
Process shutdown log. Current time is 1521464705 (in seconds).
umount[9970] had to be forced closed with exit1().

Can you clear out the log files and then after the next crash copy off the log file into a PDF file and paste that here for us to see. That way we can try to isolate whats crashing.

I added the system.log file located in /private/var/log/. Is it the correct one?
