There is a lot of good talk about the Optima battery. However, the owner of Alternator & Starter of Wichita, Kansas does not have anything good to say about them. He says that they have problem holding charge after sitting for a couple of weeks. Suggests diesel owners go with the Interstate battery. As for me, I am picking up a thousand-amp battery from Sam's Club. If anything goes wrong with it, they take it back with a smile. Also, if you want a two-hundred amp alternator, contact Alternator & Starter at (316) 265-8990. The owner's name is Nenad Dakovic. To keep it simple, just call him Ned. Tell him that alfred odom (the fellow with the black mercedes) told him about you.

Peace
