Two 6 volt vs two 12 volt run time
I was just informed that two 6 volt batteries would run the residential refrigerator many times longer than two 12 volt batteries. I wonder if this is just hype?

an amphr at 12v is 12wH
does not make any difference, if its (2) 6v in series or (2) 12v in parallel
total watt hours or amp hours will be the same
the difference becomes noticeable in useable lifetime
when you regularly cycle them to 50% SOC
this is where (2) 6v will out last (live longer) than (2) avg 12v car batteries
this all changes if you are getting quality 12v AGM batteries designed to be used, and your keeping them above 70%, not down to 50% regularly
NOW whaat was it the the dealer said ? His words ?
don't paraphrase
did he say run longer (for your fridge)
or LAST longer, meaning longer life
for the same ampHrs, NO they will NOT run the fridge a lot longer (aka hours or days camping)
they will most likely 'out live' a OEM 12v batteries that would normally come with the TT
unless that is a pair of NICE AGM batteries
