I have a 2005 suburban it has a 160 amp alt stock. It has a 6 month old interstate battery That is not that great
I was thinking of getting the factory second battery tray and getting a die hard platinum and putting the interstate as the secondary battery in the passenger side tray. I will not be putting a battery inside as I don't want to lose any more space.
Option 2 is getting a dc power power dual alt kit with a 185 amp alt coupled with the 160 I already have this seems to be a better idea to me but I don't know
