I like the idea, but It is saying to replace the main with the small battery and place the bigger one as the aux. I'm going to be adding a full-size battery as an aux already and I don't have a need to replace the main now as I will have so much battery power, it will take a while for my accessories to catch up. I have heard great things about the Odyssey's though. A bit more expensive than the Optimas and probably worth it.

Now if all I was trying to achieve was to have a spare back-up battery, I could put 2 of those smaller Odyssey's side by side in the main battery location and isolate them there. But I want more juice (amp-hours) for the aux.

Got off the phone with a local car audio shop. They are more than happy to do this project for me. So, now I gotta swing in and let them have a looksee. My main rule is keep it factory looking so in this case, it's gotta be completely hidden.

I would LIKE to add a yellow top as an aux. I need to pull the spare out and maybe pop that panel out from drivers side trunk area and see what i'm dealing with.

I'm thinking about heading over to a local car audio shop since they deal with electrical stuff and leave the off-road stuff to the place I went to last night. Maybe they can use their fiberglass sub-box skills and build me a panel where the stupid *** flashlight in the rear is that will hold a full size battery. I could even carpet it in black and it would look factory. I think this will be my best bet at this point and it shouldn't be as expensive as installing a full blown sound system that a lot of people spend their money on... - See how I have to say it to justify spending money??? So now I gotta make yet another appointment... lol.

just so you know, we have a semi truck with 4 massive truck batterys and a almost 600 dollar fridge that is a true 12 volt compressor not a 115 running off of an inverter and its a small fridge maybe 2 feet tall and 14 inches deep with a freezer and in 10 to 12 hours the low batt alarm goes off which cuts the power to all the hotel loads, so what im getting at is i would expect that if you run a 12v inverter with like a dorm fridge you will maybe get 1 or possibly 2 hours before you have to start the vehicle to charge the battery for probably half an hour and those electric coolers are just about as bad, except with them you have to be real careful with the 12 volt plug as they will melt down due to high current useage and crappy connections. just something to consider

I was never planning on running an inverter (DC to AC) off my battery. Everything will remain DC. ARB, Engel, etc make very power efficient fridges that I plan on getting.

Re: Secondary Battery Ideas!!!

being able to run a small inverter isnt a bad thing , esp. with all the battery powered tools available now, A small Impact is very handy and to be able to charge the batteries on the go is golden! or lights for a repair on a night run.


plus its fun to run a laptop with GPS software to track where you are going or where you have been.

Then there is the festive christmas lights as well!!

I think mine was a 400w That i used to carry, It was about the size of a book and connected through the lighter or could be directly wired to the battery . I stored it under the passenger seat ( I had intentions of mounting it to the fenderwell but that never happened)

If you don't like the idea of mounting the battery under the car like the person did on the other forum becuase it hung too low then you could get a gel battery which is skinnier and then you could mount it on it's side so you don't have to have extra room for the terminals on top. this should give you a bit more space and keep the standard look.

You could try something like this...

Re: Secondary Battery Ideas!!!

I struggled with fitting a second battery in our 2012 CRD with QL - my last 4 Nissan Patrols all were fitted up, and I needed to run my 12v fridge when travelling with our van. We regularly stay out in the bush without mains power and cold beer is an absolute.
In Australia here several have fitted an aux battery in the space under the passengers seat. In the QL there is no room due to the electrics but in the steel sprung vehicles it can and has been done.
Grand Cherokee wk2 Second Battery - AUSJEEPOFFROAD.COM - AJOR
I used a different idea - as I only use my fridge when going away, the battery can be mounted together with the fridge and other gear that only gets packed at that time.
I built up a module that bolts into the back, and slides in and out very easily.
This has worked out well for me.
I have a second battery isolator mounted down beside the main battery and a twin cable and running to the back with an Anderson plug. The second battery is charged by a 30a DC to DC charger and when the module with the battery is mounted in the back I simply plug it into the cable.
I think also with a bit of research a second battery could be fitted by turning the spare upside down and mounting a second battery in the space.

I just got back from a small road trip yesterday. One thing I realized yesterday morning was there was some space under the rear passenger bench. It was dark so I gotta take a better look. Is that what you were implying? Maybe some flat Odyssey batteries. or something there. I haven't planned on using that space anyway.
