Good Evening All,
Just back from another great weekend in the Big Baby. We were boondocking at the Nascar Races in Loudon and I was anxious to fully access and understand how much power I could get from my house batteries via the 2000 watt inverter.
First couple of days when we turned in for the evening...(evenings have to be without generator noise) the inverter read approx 12.5. We watched TV, we had lights on and off and the fridge was running on Propane all night. In the monring when I got up, the Inverter would read anywhere from 10.4 to 11.4. Then I tried to start up my Keurig coffee maker and everything would go off...No TV, no 110 lights...nada. I gathered that my coffee maker was too much draw on the batteries, so I started up the gennie for running the Keurig.
Last night out we started our quiet time with the inverter saying 12.3 and hubby left the TV on almost all night (with the accompanying satellite receiver). I woke at 4am and shut it off but then when the pups woke me at 6:30...there was no power at all from the inverter. Everything was flat. I tried to start the Gennie and it would not start. When I started the ignition, the gennie started up fine.
I have 4 house batteries that are original to my 2005 Revolution coach. They are 12 volt.
My questions are....
1. DO you think it is normal to only get about 12 hours of TV and receiver use out of 4 batteries?
2. Does the Generator start using the house batteries? And is this why I could start the gennie once I started the engine?
3. Could I have just one bad battery and would this cause them all to get sluggish or discharge quickly?
4. If I figure out it is just one or two batteries that should be replaced is it advisable to just replace the bad ones or should I replace them all?
5. Right now I have the original 4 - 12 volt batteries. How can I figure out what kind they are and do any of you have suggestions for my options for replacing them? Brands?...Types?...etc...
Thanks in advance for your assistance. I am still loving my new toy and really enjoying being the main driver of the Big Beast...
