In another thread we discussed my Infiniti G37 that eats batteries. Considerable testing has not found a single clear cause. I think I know why the current one failed and I think I corrected it but the battery is not holding a full charge now probably due to repeated draining.
Anyway, whether I have found the cause or not, it is time for a new battery. A little research reveals that most car batteries are made by only three manufacturers. To different specs of course but this still makes me think there is more marketing hype than real differences.
I also did not realize that hot summers are harder on batteries than cold in terms of longevity. It is hot here.
Consumer Reports' tests on various batteries are all over the place with Die Hard and Duralast (which are the same battery ) ranking pretty high. But, no real clear winners in my opinion particularly in the size I need (35).
Now the AGM type batteries have caught my eye. Optima in particular.
They cost almost twice as much as a decent quality lead-acid battery.
So the question is: Is there any compelling reason to spend that much for a battery for a road car? (The fact that it is sealed does not really come into play since the car will not be going off-road (on purpose) or on a race track (yet)).
Opinions welcome.
