This car battery testing could have been better but confirmed that wally has the battery deal. But he didn't test Opt yellow top battery which does something lead battery's can't do come back to life after being totally discharged 300+ times which is more important than max amp power in Honda's with duel mode charging.
I find it intriguing that most of these batteries are made by the same company with wild swings in price depending on retailer. I will however say that optima AGM batteries have a definitive place for use in race applications and if your car sits for long periods of time.
amg battery's also charge very fast and discharge very slowly when compared to lead acid. If driving the car every day-lead acid better. But duel mode Honda's change that and make amg battery's better than lead acid and should have came from the factory when you bought the car new. But hey new tech coming out all the time and any car is out of date after just a few years.
