Two 12's in parallel is not a good combination. If you have the remotest idea one cell is shorted it is a disaster waiting to happen. I STRONGLY recommend ditching both batteries and going for a 4D or 8D or two sixes in series. Batteries have an internal resistance and when that difference is in series one will self discharge the other. They will not take up the load evenly or charge evenly.
I took out a solid state battery combiner on my motorhome with 2x12 in series, one with a dead cell. The alternator saw no load and ran away. The dash air was on high, taking 30+volts from the alternator. Blue smoke out of the dash vents, no place to pull off in bumper to bumper multilane traffic. Thought we were on fire.
Batteries in parallel can blow up or thermal run away. Look in the John Deere tractor forum for 3020/4020 insight if you need more information.
