no these transformers usually only put out about 12.8 volts which it not high enough for a battery to charge properly,it should have a spec label on it and this will tell what voltage it puts out.
if you are not sure call jayco and check before hooking a battery up.
battery to use would be a sealed deep cycle 100a/h, set the vehicle up with a dual charge system through an anderson plug set up etc.

when hooked to car the battery output is the same as the car at 14.8v, and on 240v power supply the output voltage is 13.6v. Is this still not enough to charge a battery?

Bob,
The "fuzzy" effect on your screen is probably caused by the hot 'political' air in that part of the country, it's clear here in WA :-)
