I put a pair of RED TOP AGM batteries in my Dakota about 12 years ago. One where it belonged and the other
under the bed in front of the right rear wheel in a rack I built and welded in. The battery under the hood does every thing
it would normally do. The one under the truck was hooked up to a shut down solenoid connected to the main
battery. I used my secondary battery to charged camera batteries, lap top, and run several other 120 volt
items. The solenoid kept the main battery from discharging when the truck was shut off and charged the
secondary battery when running. Both batteries are still working great today. They cost a pretty penny
when I bought them, but 12 years later they are still working great.....
