There should be a placard on those battery empty/full indicators that come with most RV's that says "DO NOT PUSH BATTERY TEST BUTTON UNLESS THE BATTERY HAS BEEN OFF OF ANY CHARGE SOURCE FOR AT LEAST 1 HOUR". So many folks plug in for an hour or 2 and test their battery while still charging and it says it is full so they unplug. Or test it right after unplugging when there is still a surface charge on the battery, then bring their slides in (high load that removes surface charge) and all of a sudden their batteries read 1/3 full. Well they are 1/3 full because they never got fully charged by their WFCO in 2 hours but they think must be bad batteries or a bad charger.
