What happens to the crystals in a RV battery?
The crystals disappear when the battery’s charged. But when a battery stays at a low charge (below 12.5 volts) for a long time, the crystals get too large to break down and the battery is busted–who knew? Charge your battery fully and frequently, and never let it drain below 50%. Your RV battery is 64% water.
Why are the batteries on my coach going dead?
The engine alternator was simply providing the DC voltage while the engine was running. Regardless of the brand of motorhome, the brand and type of converter/charger installed and whether or not any disconnect devices are employed, it’s obvious the batteries are not receiving a charge while the coach is plugged in to shore power.
What happens to batteries when plugged in to shore power?
When plugged into shore power at the campground, presumably the AC to DC converter will charge the auxiliary battery bank. All the lamps, fans, water pump, etc., still operate on 12-volts DC, just that the DC electricity is provided by the converter instead of the batteries while plugged in.
Where is the battery located on a Fleetwood?
On our unit all of the battery management functions are handled by a single black box located in the very front of the unit, i.e. where the chassis battery, radiator reservoir, window-washer fluid reservoir, etc. are located. There are three large relays located in the box.
What do I need to know about Fleetwood motorhome auxiliary battery?
The lights lit fine. Turned on the furnace and the lights dimmed. Checked the battery charge indicator for the house batteries and it showed empty. Turned the disconnect off and back on and everything worked fine for a short while, then went dim, not off.
