After putting in the TM-2025RV battery monitoring system I started to program it. One of the numbers the unit needs to compute % from empty is the Amp Hours capacity of the battery. This is NOT the number on the side of the battery (like CCA - Cold Cranking Amps). I had to call Deka's Tech Support to get the number. For their Deka DC-24 battery (supplied with our 2010 Flagstaff 8526 that number is 75 Amp Hours.
This is a VERY low number for a Deep Discharge battery (which the DC-24 is).
I installed another DC-24 the second week after I picked it up since I planned to Dry Camp. If I had known how crappy the battery was I would not have gotten a second one, but replaced the new one!
Having said that, The TM-2050 has enlightened me as to the Amps that different stuff uses when on battery.
I was BLOWN AWAY by how much power the lights use! Each unit pulls 3 amps. If you are running the TV off an inverter after quiet hours the pull can be HUGE. The bigger the set (inch wise) the bigger the draw.
The fridge uses 12VDC when it runs on propane to power the computer board and cooling fan.
If the heater kicks on at night, the blower can quickly destroy what is left of your battery capacity.
Since the TM-2025 is a new mod, I have not written down all the individual "pulls" yet but I intend to post them when I do.
Hope this helps,
