After spending $1175, Wandrin Wagon is ready for travel to the southwest for my winter stay. The old batteries were no longer holding a charge. Voltage readings of +/-12.0 was not going to do much good when dry camping.
Since I plan to dry camp a few times as I head south, those batteries need to hold a charge for evening reading, running the inverter for the computer or charging the iGadgets. Those low voltage readings would not allow that to happen.
Considering my hitch up on Sunday, I panicked and called the local mobile RV repair guy on Thursday. By the end of the day I had four new Trojan 6-volt AGM batteries to replace the six and a half year old Trojans that were there. No complaints. They have served me well.
Now I have six more years of nomadic travel to recoup this battery investment.
Note: The batteries are recharged with 300 watts of solar panel. Parked in trees with hookups are the rare occasions when the onboard converter/charger charges the batteries.
