East Penn makes the automotive Duracells, they also make Deka & other brands. The advantage of getting them from Sam's is a 3 year replacement warranty instead of 2 years from Batteries Plus (and Deka from AP stores that carry them). I've had Interstate Mega Tron Plus batteries last a really long time, but their quality doesn't seem to be what it used to be, and the MTP ones come with a ridiculous price tag. If you run a lot of power using accessories, a battery isolator & a deep cycle battery are the way to go (IMO, like an RV or boat).
