put this on the truck in a place where Engine Heat will not get to it.
--- for myself, I zip tied it to the plastic shelf between the Radiator and Grill.


I leave the DC leads connected to the Battery all the time.

I plug in the shore power if it is cold, or I won't be using the truck for a few weeks or months.

4.5 amps, will do everything your battery needs.

agree with ^^^ post.

the cable between the two batteries, must be big and Fat, with large brass terminals.

Place a Digital Voltmeter across the two battery positive posts.

The difference should be 0.00 volts, especially for a battery charger at low current levels.

That IR gun will also work to find a Crimp Terminal that is going bad, IF, the load thru the terminal is high enough to generate heat.
