Its too short to reach just about anything so apparently its just a tap on the battery, but for what?
Call me a prude BUT I would take that 12V wire off the battery terminal (after first taking the complete NEG cable off the battery) and put a fuse on the line going to the tender if you get one. If not, I would remove that set of wires by first removing the complete NEG cable off the battery. If anything touches that positive wire to ground it'll cause quite the spark, possibly hurt someone, and possibly ruin sensitive electronics. Just my experienced opinion (experience in preservation of self, others, and property).
