I have recently spent a lot of time trying to learn something about batteries.Im only on week 1 with my new Duracell Batteries they were only $105 bucks each! I have had a Duracell from Sams Club in my wifes Sante Fe for about 2 years and I have not had any issues, the car starts right up even when its 10 degrees outside!! As for the truck I love them so far, truck fires up a lot faster then it uses and for the price, I couldn't find anything that gets close in my area.
