What is the max battery ahr this will work with, i have 6v deep cycle battery's with 232ahr that need some desulphation.

The GENIUS10 will work with a 6V 232Ah battery.

I have 2 6v batteries connected for 12 volts. Can I use this charger and my solar or must I isolate them?

We do not recommend charging batteries from multiple sources simultaneously.

Recommended max amp hours?

The recommended max amp hour capacity of a battery used with the GENIUS10 is 230Ah.

Would this work on a diesel truck with dual batteries.

I use one of the older NOCO chargers on my diesel truck so this would certainly work. If both my AGM batteries are drained to below 5V I have to actually disconnect them and charge one at a time till the charger reads at least 50%, otherwise after about 4 hours it just goes into an error. That’s why I wanted to go with this one, I can leave both batteries connected when fully dead and put it into “Force Mode”.
