If your genset won't crank w/ 6 AGM batteries you may have more than one problem. test the charge as they sit. To load test batteries, I have a set-up with an inverter and a small electric heater. I test the batteries individually. The inverter and heater draw about 13 amps from the battery. I let them run until the battery is down to 50% or 12.06 volts. Then I add up the amp hours and check the result against 50% of the batteries rated capacity. I replace a battery if it falls under 80%. Not a throughly scientific test, but it gives me a good idea of the amp hours a battery will give me during actual camping conditions.
