Battery issue, Aspire V15 Nitro
So about a week ago my laptop stopped powering on unless it's plugged in. I've used a pin and hit the battery reset button and let it charge overnight and it seemed like it was back to working normally, however today while I was using it unplugged it shut off with 50% battery left and wouldn't boot back up (it would start up and shut off immediately). Everything looks normal when it's plugged in, but if I unplug it now it'll work for about 30 seconds and shut down without warning.
I've downloaded the Acer Care app and it says my battery health is good. I've ordered a replacement battery on Newegg (from Acer), but just wanted to make sure that's what I need to do. Is there anything else that could be causing this issue? Windows and my drivers are all up to date.
