Noco GBX question. Normal?

[Canyon Trekker]

Old post, but have people been happy with the GBx75 instead of the 150, on the 6.7? Big jumping price and I mostly use my gb40 to jump other people.

I can't find a GBx150, but there is a GBx155. Essentially, the GBx75 is about half the current of the GBx155. (2500A to 4250A) However, 2500 amps will certainly start a diesel if it is in a rather healthy condition. The issue comes in as to what the trucks battery died from in the first place. Varying conditions may require more, or less available amps to start. If the truck doesn't start the first time jumped, there is no guarantee that it will be capable of starting with a second attempt with either unit. But the GBx155 may (again, situations vary) be able to have a second chance or a longer crank time than with the GBx75.

It's all about capacity for a prolonged attempt to start. Typically, with the occasional lights left on, it should be fine. The term, lights left on, would be if you added lights not controlled by the system, which would automatically shut your lights off. If the truck died mysteriously without added accessories, you probably have a short that may not allow the truck to start anyway. And the Noco will likely fault if it sees a short. Of course, the OEM batteries have a reputation for going dead as well in some conditions.

When it comes to jump starters, bigger is always better, especially on a diesel. Do what I do, carry the Noco and a set of jumper cables, should the Noco fail.
