The gps rcvr does not have a batter but will indeed support an external battery. I attached 2 AA batteries in a external easily replaceable holder and ran the 2 wires to the receiver 10 pin plug. (At least I think it was 10) I change the batteries every 2 years not so much for voltage as concern for leakage. Then use the old battery in my wireless mouse.
