Grip the battery cable pull tab, located to the left of the battery.

Firmly pull the battery cable straight away from the motherboard shield (toward the battery) to disconnect it.

This bundled cable is fairly stiff. If you're having trouble, re-grip the pull tab close to the head of the connector and gently walk it side-to-side as you pull.

If the cable pull-tab feels fragile or rips during this process, remove the motherboard shield and disconnect the cable using a spudger.

When the battery cable comes free, it might push up on the motherboard shield. Don't worry, as this won't damage anything.
