----------
I suspect your battery has a high internal resistance that is being killed
by the starting surge of your circuit. The other sources have a low enough
resistance that they can put out enough voltage to put the circuit into
its normal operating region. Your battery cannot and so it simply remains
in the startup state. Try putting a large cap across the battery before
connecting it to the circuit.

Your circuit is probably acting like a negative resistance.
