There are troubleshooting steps available to check whether the converter is operating. First thing to check though is the two 40A fuses in the middle of the power panel. Those blow to protect the converter if the battery is connected with reverse polarity.

Your converter is not converting, and your battery may be gone as well.

I doubt a big battery will do anything about high frequency noise from the charger, that will just pass it by as its in parallel with the charger and loads. A choke would do a much better job if there was a problem. Voltage surges yes, it would likely help with those. But a small battery like a motorcycle one would do that as well.

The battery does serve one other useful purpose even if you're not boondocking: it acts as a big capacitor to filter DC. The converter uses a DC-to-DC converter after rectifying the AC, which still has some noise on it without something to filter it. The battery will also help protect against DC power on/off spikes.

The slide works just fine directly on the 12V charger with no battery at all installed. In that sense it does work on shore power (as long as your charger is operating properly). 

If you always had shore power at your campsites, never used the trailer during the day while on the road,  and never used your fridge on 12V the only reason  (a good one) to have a battery in an rPod is to operate the emergency breakaway braking system. All your other 12V stuff will run from the charger directly.

To run the breakaway system a little motorcycle start battery or the equivalent would be more than sufficient. Or you could just get a breakaway kit with an integrated battery.

I don't know if I gave anyone the impression that I thought the slide works on shore power.  It's pure 12v.  But, if a battery is low or even dead, plugging into shore power will almost certainly and instantly put 12v into and out of the battery (through the converter/charger), allowing the slide to function.

We operate our 179 slideout on battery power all the time - even when boondocking (but we use a solar panel to keep it charged up). Shore power is not necessary to operate the slide with a fully charged battery.

While you can simply detach the negative terminal wire, You may want to put in a battery cut-off switch to use when it will be unattended for a few days. That will prevent the parasitic power draws of the LP/CO detector and the TV booster if it is left turned on along with the refrigerator and thermostat. If the battery. Also, if it is a flooded cell battery with caps, check the electrolyte level and add distilled water if needed, then charge. Take the battery to an auto parts place, Sears, Walmart, or Batteries + Bulbs. All of these will test the battery for you. I used it recently to verify that my batteries were still OK after inadvertently allowing them to run low on water.


I purchased a load meter for my batteries so that I can know immediately if the batteries are going bad. I use two 6V golf cart batteries in series; the load meter I bought has indicated ranges for 6V and 12V batteries.
