The Best Diesel Batteries
These are the perfect heavy duty batteries we needed for our Dodge Ram 350 Diesel Truck! Perfect cranking power for cold mornings as well as any time of day! And a great value for our money to boot! Thank You 😊

Seller is dumping defective batteries
Interstate batteries have a good reputation however I bought 2 on Amazon both were bad out of the box. They put a green date sticker on indicating a nov 2025 date however the molded in date is feb 2023 . Upon checking the batteries with a battery tester and bringing it to a interstate dealer the batteries both show bad cell and one had a SOH (state of health) of 31% with 293 cca battery rated for 925 the other SOH of 7% and cca of 70 I feel like this interstate dealer is using Amazon as a dumping ground for defective batteries.

Excellent 👍🏾
Works perfectly. I have a fridge, microwave, PlayStation, and an air fryer in my truck, on top of other accessories. With the deep cycle capabilities it's able to last and not leave me stranded. The price was good and I'm very happy with my purchase.
