Concept D3 Battery Lights blinking

There are 2 orange lights on the right side of my computer next to the battery charge port. Typically one is solid and the other is flashing slowly when charging.

They are both flashing more quickly now and my charge does not work. I can wiggle/adjust the charge cable which makes it charge again, returning the lights to normal. After 5-10 minutes, it stops charging and the lights resume blinking

Is this a battery problem, a charger problem, or something else?
