So without a solar panel setup, or home battery tender, what would be the best method to ensuring the batteries don't die, and running a power efficient cooler/fridge (12V .74Ah type)? Note: Prius doesn't have an alternator - the 12V battery sends a current to the traction battery to signal it to turn on the engine - so if the 12V battery is dead, then you'd have to jump start it.
And would you need to get a dual purpose AGM battery (starter and deep) to be able to jump start the car battery? i.e. starting/deep cycle like the Optima Yellowtophttps://www.amazon.com/Optima-Batteries-8014-045-YellowTop-Purpose/dp/B000MSBUA4 . This one is rated 55 Ah.
The portable cooler/fridge (DC) - https://www.amazon.com/Dometic-Electric-Powered-Cooler-Freezer/dp/B01MRDNXPL does for .74 Ah - thus 55/.74 = 74 hours -> about 3 days to safely discharge the Optima battery.
I am mainly concerned about very cold winter use. The heater in the Prius is too loud and turns on too frequently to be of use during the night so that would be off (would use a sleeping bag), and then I would leave the car on ready mode overnight to power a mini space heater, and to recharge the 2nd battery.
But over say 8 hours every night of recharging this via the battery isolator/DC-DC setup, would the 2nd battery top out?
