One thing to watch for with long times on the charger built into most converters, as they are not typically sophisticated 'float chargers - maintainers" but rather just bulk battery chargers with a known top voltage limit, is that they can cause electrolyte loss due to out-gassing. Periodically (at least every month or two) check the battery cell liquid levels and top up with distilled water as needed. If you have 'maintenance free' sealed batteries you might think about a true battery maintainer build for such chemistries so as not to shorten the life of the expensive batteries.


There are some modern/more recent converters that have better battery charging technologies, but verify you have one of these before just walking away for any length of time from a plugged in RV in storage...
