But for the sake of keeping it simple what can I expect if everything is off but the frig? Just trying to get an idea of what to expect. How long are you getting on batteries only. Once again thanks a ton for all the replies. I can't thank people enough for what I have been able to learn off this forum.
Like Twinboat said ... maybe 2 days.
You'd need to actually have running and start amps over time to figure it out. Then you would need to know the combined amp rating on the batteries. Then you need to know all the parasitic draw (the stuff that is running that you didn't know about)
Or .... fully charge the bats, run (just) the reefer for 8 hrs. and check the charge percentage remaining. Another guess but close enough.
There's a voltage vs. charge percentage table/graph .... handy to have. Keep the discharge in the green and preferably the upper green.
