Battery runs out at 100%

My MacBook Pro of 5 years has recently ran into a problem when connected to my LG 25” ultrawide monitor, where if not plugged into power, no matter what percentage of battery it’s on, shortly after booting up it will shut down. I try to turn it back on and it gives me the “low battery” screen, and won’t turn back on until plugged into power. Even if power is unplugged after booting up again it won’t “run out of charge” again until I boot it up the next day without being plugged into power.

Attached above, mac info, battery info. Also Macbook now shuts down and gives me the low battery screen even when not connected to the monitor.

Forgot to mention this happens only when booting up from being shut down, and about 20 seconds after logging in.

Thanks

@zpyrakis - Well the battery looks OK, can’t tell much more as you didn’t have the charger connected. Did you have the display plugged in?
