85 AH AGM marine deep cycle battery for my Prius

I am not sure whether the vehicle recharges its 12vdc battery at a faster rate depending on its level of charge.

Changing out your deep cycle battery to one with more amperage would allow it to more easily feed a bigger inverter, but, therein lies the danger. With a bigger inverter, you will use heavier loads, which will drain the battery faster.

 

You're all over the place with vehicles I wouldn't fix a generation 3 I have two of them sitting here that's just not worthy of the repairs generally least that's my take on it. Going from a Prius to a sienna van that's quite a change gas and everything I don't think you'll run the air conditioner all night in the Siena van unless you're getting a hybrid one which that's quite costly My 2002 or whatever sienna van was rock solid 1MZFE engine still running today with over 300K on it a friend of mine owns it and drives it daily It's a solid vehicle but it's nothing like the prius's gas mileage and run all night and air conditioning and all that business I would think with the sienna van you'd be able to get a battery bank and have two good size solar panels on the roof when when and desired things like that give you more space for sure depends on how much you're moving rolling driving etc.

 

We don't know what loads you want to run off your 12vdc battery.

If you increase how much current your 12vdc can run, a week later you will be tempted to get som other big load.

 

Some people install a 2nd battery on the drivers side. It take some minor modification,
and they install an automatic switch when one battery gets low. It also adjusts which
battery gets charged. They even install a solar panel for charging.

If the engine is burning oil, a remanufactured one would probably be best, unless you don't
drive a lot of miles. I installed the lithium hybrid battery in may. It lasts a very long time when
I have the A/C on when the car is sitting with the dogs in it. I'm happy about that!
I've been very happy with it.

 

The 1200 is the max, and it's not for long periods of time.... So the car can handle it.
And since the car is in ready mode, the inverter is running it, not the 12v battery.

 

It depends on what you are running. Some people have microwaves and refridgerators!
A 2nd battery in parallel would give you the little extra insurance in case you forget to start
the car and drain the battery.
I live in my Prius half the time... I drive and drive and drive..... hours on end.

Happy Camping!

 

Oh, you might want to check out walfart, they have lithium batteries now.... And they cost less.

 

So if you're happy with everything and everything's good and you don't spend a lot of time driving the car just living in it oh hell you can probably run the air conditioner and the heat with it rattling away for quite some time My guess would be and then when it totally bites the dust then you do whatever it is you're talking about. Even an older sienna van like my 2001 or two with a few batteries in it and three panels on top of the roof depending upon where you are that might run you pretty good for a good while I don't generally sleep with heat on ever even when it's 12°. I put it on in the morning when I get up but I sleep in the cold better for my breathing and everything I used to live in a cabin in Alaska Wake up in the morning and it'd be minus degrees in the cabin fire up the jotul stove and 45 minutes you'll be opening a window
