Installing 2nd battery

Installing 2nd battery

Postby Collins.T [OP] » May 22 2012, 2:43am

So ive been thinking for a while to install a 2nd battery in my truck to run all my extra stuff (system, fog lights, and more lights to come). Has anyone done this recently? Besides the battery, what all do I need? would I need a alternator with more amp output? the one I have now is 130 amps I believe. thanks guys

You're gonna need a dual battery isolator.

So on that Isolator, any suggested amperage I should get? I not running any crazy electrical load like a winch or anything. maybe like a 120?

Depends on your needs. I'd discuss it with an isolator retailer in your area or contact a manufacturer and discuss it with them.

You dont HAVE to run an Isolator. You can run the batteries in Parallel. An Isolator is to protect both batteries from running down and leaving you stranded. If you run them in parallel, the alternator charges both batteries equally, but it also draws current from both batteries. If you go without an Isolator, make sure to wire them correctly and not wire them in Series or you will really screw up your electrical system because you will be doubling your voltage from 12 volts to 24 volts with the ignition off and 14 volts to 28 volts with the engine on
