AGM Batteries

Question. My stock 1937 Packard 120 came with two Optima, red top, 6 volt, AGM batteries. With the engine running I noticed that the generator gauge indicates no charging. It does work and shows much discharge when I turn on the headlamps. Will the generator damage the AGM batteries because it's not designed for AGM? Should I disconnect the generator or should I replace the AGM batteries with traditional lead-acid battery? Is there a work-around using AGM batteries? I found myself stranded with dead batteries - no fun...my wife was with me!

Looks like I'm running the vehicle on batteries only. I now trickle charge the batteries when not in use
