Finally checked the house batteries
My son borrowed the MH last December and used to over a weekend. When he returned, he said that the house batteries didn't last the whole weekend. He did mention that they turned on lots of lights at night. Since the status panel showed the batteries returned to full strength after the trip, I didn't think much about it. Yesterday I decided to pop the cell covers to check the water level and discovered what appeared to be a "gel-like" substance on a couple of the cells in each battery. I pulled my receipt for the batteries and was surprised to see the batteries were 44 months old and the warranty was only 30 months. I decided to go ahead and replace both house batteries. The status panel still showed that the batteries were fully charged (with the shore power removed). That is the last time I will believe the panel.
