I bought a leftover 2018 with an August build date in June of 19. So I figure that it sat for about 8-9 months on the lot and it had only 60 miles on the odometer when I picked it up. I also understand from this forum that the factory batteries tend to be crap.

I want to replace both batteries before next summer (2 year mark from manufacture) with something very reliable. NB: this is a weekend driver and often sits for a couple of weeks or more between long drives. Also I park in an urban parking garage so a trickle charger is not an option.

Any recommendations on brands?

Thanks, do they make one for the aux battery as well? I can’t seem to find it on their website.

I think the combination of driving on weekends only and no trickle charger is going to bite you in the ass......

That I don't know. This AUX battery is new to me. It's on my list to investigate and see if it can be deleted from a true dual battery set up.

Genisis dual batt setup eliminates the small batt. I love mine.

It’s an expensive but worthwhile upgrade. The genesis dual battery with odyssey batteries. Excellent products that’ll provide years of great service
