How to Recharge a Coleman Trailer Battery

Coleman makes a range of travel trailers used for camping. Coleman makes pop-up, hybrid (hard walled with folding sleeping quarters) and full hard-shell trailer campers. Coleman powers these rigs with electrical hook-up ports, propane and battery banks. Late-model Coleman campers use deep-cycle batteries in their power panels. Over time, these batteries lose their charge and need to be brought back to life.

Instructions

  1. Generator

    • 1

      Locate the battery charge lights in the Coleman camper. Most Coleman campers have a series of small lights that glow red or green, and indicate the charge remaining in the battery.

    • 2

      Check the remaining charge. If low, turn on the camper's generator and let the battery draw a charge as you power the camper via the generator. Check the lights periodically to see when the batteries are fully charged.

    • 3

      Turn off the generator when the batteries have a full charge, and run the power off the batteries to keep down noise from the generator.

    Battery Charger

    • 4

      Go to the outside of the camper and open the battery bank housing panel, typically on the side of the trailer near the back. Remove the battery wire clamps using the adjustable wrench. Inspect the battery terminals and clean off any corrosion.

    • 5

      Clamp the battery charger cables to the battery terminals, connecting red to red and black to black. Turn on the battery charger and set the charger to "DC" to get a proper current and charge into the battery.

      Check the charger every hour and check the gauge indicating the current level of charge in the battery. When the gauge indicates a full charge, turn off the charger, disconnect the cables and reconnect the camper cables to the battery. Close the panel.
