Whats the Advantages and Disadvantages of putting dual batteries in my 92 2600 4x4. I would like to get an isolator and hook it up with a truck battery for starting and the regular things the car runs on. Then the second battery will run the 4 flood lights i would like to get for my light bar i would also like to get. I will also use the second battery for my amp and an air compressor and fog lights on the bumper. Any ideas or comments would be great. Thanks abunch.

 

sounds like you have a good idea.
going to up the charge power on your alternator also?

 

No i dont think i will upgrade the alternator until i can tell if i need to. With the strain on the secondary battery alone i dont really see a need to. The drain will only happen when i actually use the extra accessories and then charging the rest of the time. I will be putting 2 volt meters on the batteries... One for each to monitor the discharge of the batteries. Any ideas on the advantages or disadvantages of this?

 

I honestly wouldnt be able to tell you
never gone that deep into battery drain
