Introduction
If your Dell XPS 13 (also known as Dell XPS 13 Infinity Edge Ultrabook or Dell XPS 13 Skylake) has lost its ability to hold a charge, you most likely have a dead battery, which requires replacement.
A functional battery provides power to your laptop. Eventually, laptop batteries will rapidly drain after going through a repeated amount of charge cycles. If you notice that your charged battery is draining more quickly than usual, consider calibrating your battery to determine an accurate charging capacity. If you continue to notice significant drops in battery percentage, you should replace your battery.
A punctured battery can cause a dangerous fire. If your battery is swollen, take appropriate precautions.
Make sure to power down your device before you begin.

Pull the battery cable connector towards the battery to disconnect it from its socket.

If the connector is stubborn, push a little at one side, then the other, to "walk" it out of its socket.

If you have trouble walking the connector out of the socket, use the point of a spudger to gently push on the connector indent to slide the connector out.

Open the display and press the power button for five seconds to drain any remaining charge from the system.
