Testing 6V Batteries
While chasing down a charging problem with my truck last fall I had my two 6V in series batteries load tested at an auto parts store. They tested bad and Costco replaced them since they were about 8 m...

Bottom line is that if they don't power anything after charging them, they need to be replaced. I'd suggest you find the source of the draw that is killing the batteries or you'll be destined to a life of battery replacement. It may also lead to a bad situation after setting up at camp.
You do have a disconnect switch or remove a battery cable while in storage?
They didn't fail. I noticed a dimming of lights when another light was turned on and wanted to test the batteries. I have a disconnect switch and use it in storage.
Share the model/yr/make of your TT and the converter make/model. Most folks don't know that 6V GC2 batteries need 14.8V on a steady diet for longevity and performance.
Do you have a hand-held meter?
Arctic Fox, 2001 with a Progressive converter but I don't know the model. I added a charge wizard. The first pair of 6V batteries lasted 7 years and were only replaced because I thought it was time. I have a volt meter and I don't think it is charged at 14.8V, more like at 13.5, IIRC.
Yeah, some of the older PD chargers didn't get up to 14.8V in bulk stage. 13.5V will charge a pair but it will be a long time and there will still be a drop in capacity.
I'd suggest to measure voltage at the output of the converter and see how high you can get it.Report back.
Goosing the charge that exists from your trailer converter with a higher voltage stand-alone charger or power supply is one way of maintaining a pair of 6V's. But, since you have 7 yrs. out a previous pair, something has probably changed. One suspect is a failing circuit breaker/fuse holder on a battery cable. If it sets up enough resistance, current will have a hard time going either way. Check those connections!
