Batteries work great in my Cummins 8.3

Finally got them installed in the Safari Serengeti motorhome and it cranks over really fast with these 2 new batteries. Items were packed well in a nice thick box cardboard box with good protective support, and shipping was fast via FedEx. Satisfied with the purchase.

I have only been off shore in my boat with my new NorthStar battery installed one time, but it performed flawlessly! The Battery Guys had the best price on this battery and with free shipping! It was shipped on the first business day and I received it four days later. Fantastic price and service.
