Hey just a few question about installing a second battery. First the reason for wanting a second is so one battery can run my radio and lights with the truck off and the other battery just starts the truck. Ive seen on another forum the way they welded up a bracket to fit the two batteries perfect and was bolted on the sidewall of the driver side. My question is does having a second battery require anything else to be installed? Does it put stress on my alternator?
