Depending on the model heating pad that is stuck to your tanks, 9 volts is just about right for 2 tanks running of the 4.5 amp models OR if you are on battery and the DCV is not 13.5 volts (something less) it could be the 5 amp model, just pulling reduced amps due to the less than 13.5 condition.
You are correct, that the pads will modulate on their own based on the temperature of the THAT tank. The temp will depend on whether there is water and how much.
With a full tank the heater will be on a long time to heat the water; then off a long time while it cools down. An empty tank will be on almost all the time because there is no heat sink to hold the heat and the plastic will cool quickly.
