When is a 6V Battery Dead?

We have a new 5r which has 4 6v batteries wired together in both series and parallel per CC instructions. We have a 1000w inverter and a residential fridge.

We seldom dry camp but I wanted to know at what point I should consider the batteries discharged? The simplest way for me to test I would guess is checking voltage, correct?

They're tied together to make one big 12V battery, or in your case two 12V batteries. As such follow the recommendations for voltage and state of charge for 12V batteries. One thing to note, if they're 6V 230ah batteries the voltage doubles, but the ah capacity doesn't. You still have 230ah per pair because the rate of discharge is at the now 12V level.
