Well Sir,
First off, what model, model number, gas, diesel, what? Has it EVER done this before? Has it been starting normally each and every time you've needed it, up to this incident? And, you said it cranked but, didn't start. That's not really a sign of bad batteries. If any battery was bad, it wouldn't crank. Need a bit more info to try and help here.

If my batteries are switched off, the generator engine will turn briefly but not enough to start.
if the battery voltage is low it could act similarly !
