Those are recalled a little bit of research that I did when I was trying to up the amps was that very thing that you're talking about. I stepped up to the 90 AMP but noticed the going much higher wouldn't get me anything where I really need it when the engine was idling. I mean at some point you can start just recharging the battery faster I reckon... But the problem is when the temperature is hot and I'm running the AC and I'm running the electric fans and I'm at a stop I went ahead and not only got the 90 AMP but got the yellow top optima battery as well...
