For reasons that are long and complicated, I'd like to carry a spare battery in the back/trunk of my TB. How could I keep it charged up as we go along ? Plug it into the cigarette lighter on the back of the separator between the two front seats ?
Best way to charge a battery stored in the back of the SUV ?

You can just run it inline with your trucks battery. about 25-30ft of wire and a few terminals will keep you a full battery. I have an extra but its a hicap to power my amplifiers.

You will need to run some 2 gauge wire in parallel from the original battery to the slave. Stick with the same amp/hr ratings.

You could just ground to the frame at the battery since the battery up front it grounded to frame as well.
Isolators have three terminals. Two for the positive terminals of each battery and the other for the alternator. Grounds are connected to nearby sheetmetal or frame.

That's one reason. Saved my bacon the other day when we had left the car at an airport for 3 weeks.
Another is to connect my high pressure air pump to it
Another is to parallel it with my inadequate (but can't make it any bigger on the frame) trailer battery when we are "boondocking" over night in the cold cold winter.
You should not have a battery in the same compartment as the passengers, it can put out harmful fumes. You would need a special box ventilated to the outside of the TB.

Not a problem with AGM batteries.
AGM batteries only need to be vented to atmosphere, they do not need to be in a sealed box vented to the outside like wet batteries, and can be mounted on their sides or ends if needed.

my folks had a '67 ford econoline which had the battery under the driver's seat (about a foot and a half left of the engine, which was between the two front seats)
when the alternator over-drove the battery and ran it a bit dry, you could smell that something was wrong.
it did not kill me, but what did we know way back then?
I would at least put in in a plastic box to catch the acid if it gets excited. They are pretty cheap at the boat section of your local store, if no where else.
