Jump Pack

[David Hummel]

I am looking for a jump pack to keep in the shop and one to keep in my truck. Any suggestions? what size would I need? The biggest thing the shop one would be used on is a John Deere 9500 combine. I have not really looked much into them yet I would just like some ideas.

I have a JNC 660 jump box. Have had it for 10 years or so. Always worked good, including starting diesel engines.

Plus one on the JNC660.

FYI While the unit or box or specs may make it hard to find, a good piece of info to know if choosing a jump box is HOW MANY AMP OR WATT HOURS OF ENERGY STORAGE IT CONTAINS AND HOW MANY BOOST AMPS IT CAN PROVIDE........Its no more than basically a battery (and means to recharge) which stores energy, and as far as how many Cranking Amps it can pump into your cars battery, THE MORE THE BETTER . A cheap unit may have a smaller battery. Shop around compare energy storage capacity and max amps it can deliver ........

exactly, and them goofy jump boxes are a waste of money, nothing like just having a spare battery on the shelf for boosting. no reserve cranking in them at all.

Or just use cables from battery in often used vehicle......it will be charged and the anemic jump pack will always be forgotten and dead behind the seat or in the trunk.

The "goofy jump boxes" are not meant to start large engines. They're not meant to start engines with flat dead batteries. They're not meant to crank the engine for long periods of time. Wrong tool for the job, period.

If you want maximum effort, the Jump-n-Carry 1224 is the gold standard. It's about the highest capacity jump pack out there. It will do 24V at 1700 "Amps" and 12V at 3400 "Amps." I put "Amps" in quotes because it's a meaningless, unrealistic claim. There's no way those little sealed gel cells can produce 1700 Amps. There's no way those cables can handle 1700 or 3400 Amps. Even momentarily. Everything would be glowing and smoking.

Unfortunately, it's lead acid technology so if you throw it in your truck and forget about it, it's going to be dead when you need it.

The Goodall JP-12-10000 is a lithium-based jump pack that won't self-discharge sitting in your truck, AND is designed for heavy cranking and large engines. It's around $1000 normally, though.

Harbor Freight has one similar in specs to the JNC 1224. The nice thing is the 20% off coupon works on it, if you can wait for one to come along.

I’m with you on this one. 1700 Amps wow lol. The more the energy stored and the more short term high amps they can deliver the better, but they are pricey. Of course this is a lithium battery application for sure with their high capacity low weight and no maintenance as opposed to heavy lead acid that self discharge at a higher rate grrr.

Nice sparky chatting with you

I have a stanley, don't even know what the amperage is, that I keep plugged in in my shop. It has a compressor on it that works pretty good for something like a garden tractor tire or to get air in a car tire to make it to the shop. It is so handy if I have something with a low battery. Just used it yesterday on my tractor. IH D312 that barely turned with the battery but fired right up with the boost pack. Way simpler and easier than starting another vehicle and dragging out the jumper cables. What a pita. And carrying around a full size battery isn't going to happen. At work we have a few Booster Pac brand. They aren't that expensive. They seem to work pretty good at their price point.

Check out youtube "project farm" for jump packs. You'll learn quite a bit...

Used a Harbor Freight one yesterday to start a 3406 Cat. Wasn’t completely flat but wasn’t gonna start either. The downside is the boss puts off buying new batteries since he got it.
