please explain dual batteries
I would like to install dual batteries in my 79 F-100.
It came stock with a single battery.
I am aware of the isolators that are used for this,
allowing one battery for starting, the 2nd for accessories,
and the alternator keeps both charged at the same time.
Before I buy the isolator and 2nd battery, though, I wanted to
ask if there's anything else I needed? I guess I'm just unsure
on how the system knows which battery is which. Is it all handled
by the isolator, or is there some additional wiring that i will
need to do.
Thanks,
-Ferrite

It depend what your application is going to be.
The isolator is the big thing by keeping the batteries apart, the
alternator charges them both at the same time.
The need for an aux battery is for a trailer/camper/or accessories like a winch.
For camper lights and water pump, I have a R/V deep cycle battery.
In the winch application you will need a relay to give full power to the winch using a car style battery with lots of cold cranking amps.
What I do, is connect the stereo and any other accessory
to drain the aux battery.For a battery to last,you have to have a cycle of charge and drain.
If I need the power from the aux battery to start the vehicle,I use booster cables.
