Gel batteries
Hi. I have acquired two used 135ah 12v gel batteries. They are 5”x18”. They were back batteries that were changed out after a years service. I think they really have no usage. My question is how...

A guy could do some further research on the characteristics of those Marathon batteries but they sure seem like a good battery. Free batteries can't be beat.
Since they are AGM batteries, you can locate them inside, close to furnace or near to the axles.
FWIW, I have two banks of different batteries, 2 X 6V GC2 and three AGM telecom batteries. I am able to switch either bank to either 12V distribution and the converter, to the inverter, or from the solar charge controller. The AGM batteries I have will take the same higher solar charge voltages that the 6V's need. I've had the two banks parallelled for a number of years. All of the batteries are inside my trailer, the 6V's in a vented box and the AGM's on the other side of the trailer, both near the axles.
