How can I use my 12' MB 2015 with AC power only? (No battery) My 12 inch MacBook from 2015's display broke and only works while connected to an external display.

I don't want to spend the $800 on a replacement display so I was hoping to use it as a full time server, almost like a Mac mini. I don't want to risk the battery though.

Can / should I, remove the battery somehow? And if so how? Do I even need to worry about this? I know lithium batteries can be unstable if you abuse them that way. I've also had to replace one on another mbp because I abused it too.

What do you guys think?
Leaving your MacBook plugged in is not "abuse". Apple's laptops contain power management that prevents any problems. Even while plugged in, you may see the battery % indicator change from between 93% to 100%.

  My battery won't charge to 100% 
  
  
    Occasionally, the battery might not show a full charge (100%) in
    macOS, even after the power adapter has been connected for an extended
    period of time. The battery might appear to stop charging between 93
    percent and 99 percent. This behavior is normal and will help to
    prolong the overall life of the battery.
