Battery Advice

OK - Bought a new Starcraft TT in February. Have always used shore power, but just discovered the batteries do not work. Bought 2 new marine batteries - and they're flat dead. Battery disconnect is on. Is there something I need to check / look at before hauling the rig down to the RV repair shop for warranty service? thanks

  • Did your "new" batteries ever work?
    If not check for a breaker that looks like something like one of these. It will be on the positive line probably attached to the tongue underneath or frame. Follow the positive line from the battery back into the trailer...

    It may have tripped. Some are self setting and some have a reset button on them...give that a try also.

  • Thank You! So let me get this straight:
    - I should check the water levels monthly
    - Whenever I am not using the batteries I should make sure to close the battery disconnect
    - I should test regularly and make sure to have them charged whenever down to 50%
    - When they do need a charge, I should open the battery disconnect and let them charge up

    Do I have this right?

    Keep in mind if you plan on towing your trailer over PUBLIC ROADS you are required by DOT to have a working battery for the ENERGENCY BREAKAWAY SWITCH setup that will stop your runaway trailer in the event of becoming disconnected while enroute.

    I doubt if the dealship will replace any batteries under warrenty. This is more or less your responsibility to keep the batteries operational.

    We all have to learn how all of this works and not get into those circumstances. My batteries were installed in 2008 and still are performing well...

  • If the switch is on (in-use) the batteries will soon discharge and become flat dead. This method of maintenance has already damaged the batteries. Get them charged asap. Plug in the trailer and check battery voltage with an actual voltmeter.

  • How long was the trailer sitting with the batteries not being used or charge? All batteries will go dead from sitting after a few months.
  • Sounds like the converter is not sending power to the battery. Either connected wrong, main fuse open, or bad converter.
