What is the best way to charge a breakaway battery? Can I use my 12 volt battery charger on the 2 amp / trickle charge setting?
Willyswanter, What setup do you have for charging from your truck? Note this for a flatbed trailer not a travel trailer.
Anything with brakes should, if I remember correctly, have a 6 or 7-pin RV connector. If all of this is wired properly on both TV and towed, the alternator will charge the battery on the trailer. If you're using a 7 to 4 pin adapter, the battery won't charge. If you don't have a 6 or 7-pin on your truck (you definately should on the trailer), just go down to the Auto Zone or whatever and pick one up. There should be instructions in the box... Marc
