Is it ok to stay on shore power all the time?

If the WFCO goes into trickle mode as it should, the output (anywhere in the DC system) should be 13.1V-13.2V. If the voltage is still 13.6-13.8V after receiving shore power for 48 hours, your WFCO converter is not transitioning to trickle mode correctly.

I have replaced 2 WFCO converters that never went into trickle mode. 13.7V applied indefinitely (longer than a couple of weeks) will fry a battery through evaporation and bubbling.

hope this helps

My WFCO did not work correctly so I replaced it with a Progressive Dynamics unit. I look at the digital volt meter every couple of days and the Progressive unit shifts between the 4 settings. It is usually on 13.2
