We're discussed this any number of times but tech keeps changing. My old one swelled up and broke the case. While it still carries juice, I'm very leary of it.
What's the latest on one that will reliably start a 6.7 diesel with 2 dead batteries? I'm looking at the Antigravity XP-10 Heavy Duty and/or the NOCO GB150. Any better ones without going to one bigger than a car battery?
I see that many models that used to be rated for a 6L diesel are now saying 10L. Is it all BS?

As you prob know Noco is one of the big names

This one looks like one step up from the GB 150 for $350

Have two small Noco chargers plugged in right now

Farm project guy tested a bunch....

I bought this big bastard after several failed attempts with smaller ones. This does my dual batteries in my diesel when it's completely dead. Heavy son of a bi tch

I bought Noco GB70s for all the boys last Christmas. They have never failed on 5.7 L gassers. My oldest Grandaughter headed to College at the other end of the state got my never used Noco GB 100. And I had to buy another. My GB 100 has been used many times now.

My experience is they work as advertised, even on a stone dead battery.

remember



size matters

I've been happy with my NOCO GB150. I haven't found anything it won't start yet.

For sure. None of the smaller ones will start my Dodge Cummins. I'm trying to find out what will start it without having to pack around a huge power plant.

I tested mine out on a 2000 F-250 7.3 powerstroke, with dual batteries.

It's a MF'er to jump using old fashioned cables and a vehicle with a standard factory alternator. Have to let the jumper vehicle run at a pretty high RPM for about 10 minutes to charge up the batteries enough before that bastard will even think of cranking over.

I intentionally left the lights on overnight to drain the batteries. Hooked up the Noco the next morning, and it fired right up. Truly amazing how many cranking amps those things can belt out.

I bought that big bastard also. Dropped it on my foot and broke my little toe. But it will jump just about anything.

which one did you test?

I have an XP-10. Not started anything except ATV and snow machines with it yet. Supposed to be able to start my Ram 3500, but not tested yet. I keep good batteries up....

I bought it for backup in the Arctic to start my wife's Arctic Cat 1100 Turbo (no recoil starter), just in case. Never needed.

The AC has been in the shop for 15 months now, waiting for clutch and brake parts.

Probably not ever going to buy a AC again, but the XP-10 goes to our remote cabin with us. Charges iPhones, etc. too, has light... would start the Yamaha outboard also, but that has a recoil starter anyway.

Belt and suspenders.....

All I know is a small one saved my bacon earlier this year when my alternator died. I had a dead deer in the trunk and couldn’t open it with a dead battery. The jumper allowed the trunk to open. It also started the car, but quickly died trying to run it with no alternator. I’m impressed.

HULKMAN Alpha85 Jump Starter 2000 Amp. Not quite big enough for you, but plenty for my old Buick and very easy to use.

I've known any number of people who carry jumper cables in a trunk with an electric lock. I've only had to help out 1 of them, though. Some of the also have electric hood latches. I don't know how you jump one of those. I've never had to try.

I was very lucky that my car has a pass-through to the trunk from the back seat and I was able to reach the jump pack. The battery is under the back seat, but the hood-latch is mechanical so I used the jump terminals under the hood to connect.

Now Grandpa keeps the pack in the back of the car, not the trunk!

I just went out and looked, it wasn’t NoCo after all.

It’s gooloo GP4000, about 170 bucks on Amazon.

One advantage of the Antigravity XP-10 is that is has a 19v outlet for charging a laptop.

You should get one of these, give it a whirl, and report back. https://myweego.com/product/crankenstein-c154/

That does look like a horse. However, I'm looking for one that will fit under my pickup seat. I need some way to carry it out of the way.

I have an XP-10. The only test has been on a neighbors gas 5.4 on a warm day. I wonder whether it would work on a below zero day on my diesel 6.6. My mechanic recommends using two, with one on each battery but I’ve not talked to anyone who has actually done that.

If a diesel uses 2 batteries, each with 600 CCA's, that's 1200 amps. My XP-10, which is failing, produces 600. That'll start any gas engine but what does it do with any of the full sized diesel pickups?

I saw you wanted one smaller than a car battery so thought it might be 'tweener enough to work. One thing I noted on this one is an operating temperature minimum of -28F. The more common Li-ion types are listed at -4F.
