[A/S] Extra Batteries
My '97 Dodge 2500HD reg cab, long bed truck has enough room inside the
fender ahead of the rear wheel for 2 golf cart batteries. I made a HD
wooden support enclosure hung on 1/2 inch bolts from the bed above,
installed a fused disconnect box for emergency situations, then connected
it all through a charge solenoid so that these batteries charge from the
truck's alternator anytime the engine is running. So they charge when we
are out sightseeing, etc.
I have an inverter installed along with this to generate 700 watts of 110
AC. My most frequent use is to move this "captured" charge to the trailer's
batteries by running a charger from the truck's AC, but it can just as
easily run a satellite receiver, etc. It won't quite operate the microwave.
I installed a 110VAC connector on the trailer tongue to couple them up. An
ordinary extension cord allows me to park the truck nearby and still power
the trailer when it is uncoupled from the truck.
The economics of capturing this "free" charge when we are out running
around are pretty good. Cost me only a few bucks above the price of the
batteries to make it go. It is heavy, though - no way getting around the
weight of those golf cart batteries, but I guess I prefer to have their
weight in the truck than the trailer.
It has survived about 20,000 miles this way now. The bottom of the battery
enclosure box just barely shows below the fender, but you really have to
look hard to notice it. I painted it black. I have not checked the
electrolyte level in the batteries - VERY difficult - when they show a
problem I will just replace them.
