MacBook Pro Crashing when powered by battery

I have a mid-2015 MacBook Pro with Retina display and 16 GB RAM.

When I am plugged in to the AC Adapter, there's usually no crashing issues. However, if I run off of the battery, it will boot fine and start to work, but then the screen will freeze. I'll have to manually shut it down by holding down the power button. Sometimes, it will just shut down on its own and I'll have to press the power button to start it.

Then if I reconnect to the AC Adapter, it will crash again a few times in the same way.

I'm thinking this is a battery issue. Is there any software out there to comprehensively test the battery?
