It appears to be for a specific charger or perhaps accessory that was run off the battery. Trace the pigtail and verify that the other end is hooked to the battery.

I agree maybe its for a specific charger I have not seen, all I have seen use the pigtail others posted here. My best guess it is maybe for an accessory, see if it run to the battery like Dawg suggested
