A device like the ThermaHeat RV Holding Tank Heater Pad # 277-000164 will function for as long as your battery has power, but this time period can vary quite a bit depending on the battery capacity and condition. Since this item also has a thermostat the particular setting you choose will affect length of operation.

This item will draw about 5 amps of power. If used with a fully-charged 300-amp-hour (300 Ah) battery this pad should operate for about 60 hours.

You can determine the estimated operating hours for your specific battery by finding its Ah rating and dividing this by 5-amps.
