Battery Life?
Newbie here. I've never boon-docked before, and was wondering how long I can have the lights on in my TT before the battery gets to a critical level (from what I've read below half way charged is bad...

The OP is a newbie and won't have any idea what you mean by "dew point heater on the fridge". Explanation - many gas absorption fridges will have a 12 vdc heating element located in the area between the fridge and freezer sections that's intended to help reduce the build up of condensation when it's really humid. When on shore power leaving this heating element powered is obviously a non-issue but when running on battery power it's unnecessarily drawing down your precious battery reserve. ... we could probably tell him whether he has a heating element that can't be turned off. We could also further advise him how to install his own switch so he can disable this heating element, as necessary. ...
Well said, Sound Guy! I became aware of the dew point heater while my battery was aging and not charging well. I pulled the fuse and measured the current across the contacts. I saw 1.3 amperes as a constant load on the circuit. I read the Dometic refrigerator schematics. I could cut the wire from one particular "test point" and deactivate the heater. I would have to rewire the refrigerator light because the light and the heater are sourced from the same the test point.
Now I am shopping for a new deep cycle battery.
