Battery and Refrigerator fan
We just had a fan installed on the back of the refrigerator. My question is, How long should the 12 volt 27 series battery last when parked running only the fridge fan? The refrigerator will be cooli...

The small (4cf?) frig in my TT draws only .5 amps in LP mode. I installed two "3-speed" computer fans behind my frig and they each draw anywhere from .3 to .6 amps depending on speed (.6 to 1.2 amps total). I run them 24/7. Addition to this, my TT also has a parasitic draw of .13 amps (everything turned off).
With only the frig turned on in LP mode, plus the two frig fans set to low, my total 12 vdc current drain is 1.23 amps (including parasitic). I'm guessing a 27 series battery (approx. 85-95ah) would power my TT in this mode for about 55-70 hours if I completely discharged the battery (0%). Of course, discharging less than 50% is not recommended, but at least this gives you a general idea of a 27 series battery's maximum capability.
