I agree. Now driving two hours plus daily, in the dark or near-dark, I've become very aware of the need to keep the battery charged, and aware of the load that charging places on the engine. Difficult to keep battery charged with lights on and doing EOC at the same time. More amps per drop of fuel would be a good thing.
I have a plan to run the headlights up to about 3 hours off an Optima Yellow Top battery that I'll recharge nightly from wall current. It won't run the whole car, just the lights and maybe a few other specific items. An Optima D35, D75 and D25 = 48 AH capacity; Ohm's Law says that should be enough battery. I already have the headlights running off my own relays so it will be pretty easy to keep the bulb circuit isolated from the main electrical circuit.
