I'm still using the ole carbon pile resistor type battery tester. May not be high tech or fancy but it's getting the job done.

 

Can any of these capacitor based jump starters be direct connected and left alone, so they can help the starter without any manual intervention?

Who is going to try this?

 

The little boxes are LiPo batteries and like flooded cell NiCad
they can dump a lot of energy very fast. The cost is that they
heat up and go into thermal runaway. That is when they burst
into flames. Because of the Lithium they are hard to put out once
they go.

Myself if I could get the right charging equipment in the truck
I would think about a flood cell NiCad do to the high energy output
in such a short time. They also don't have the output drop or knee
that the lead acid batteries do. They are much sharper.

With the issues that the LiPo have been having. Fires in aircraft from
the system batteries and passenger;s devices I think I would not want
one near me that has been drawn down quickly trying to crank over a
cold 6.0L diesel and also light the glow plugs.


Little tidbit of info. Do you know what happens if you put the electrolyte
from a NiCad into a Lead Acid? They neutralize each other.

One is acid and the other is an alkaline.
You would end up with a hot smoking mess and both would be dead.
So you have to service each in it's own room

 

I have the one in the video
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I used it 3 times now with out charging it, still reads 75%. the first time truck was full on dead no click, dash odometer dim as can be. Put it on waited for little v-meter on it to go up to 11.5 and it started right up.

it was necessity for me to get this thing. I was working out of town truck parked in hotel garage on top floor hadn't used it in 5-6 days and wanted to go somewhere to eat ... the Truck was dead, did some research read all the reviews and next day'd it to my hotel. I have AAA but they always send out the idiot with the super compact car and small jump box. Usually takes 3 tries and yelling at the AAA operator to get me a TRUCK out here to me. Now just pull this thing out and bam! on the road again.

 

I'm considering one myself. They're on Amazon for almost half the price than if you buy it off a tool truck. In the video below it's being used on a Superduty 6.0 diesel but he claims it will jump up to a 10 liter.

that's what made me buy it, in the Amazon reviews someone mentions using is his yard for many larger diesels. plus others who used them on their diesel trucks. gotta say I love mine! Its about the size of a keyboard w/o 10 keys and about 2.5 inches thick. fits nicely behind the passenger side rear seat.

 

Just picked up a NOCO Genius Boost Pro GB150 4000 Amp 12V UltraSafe Lithium Jump Starter. Reading the manual that came with it says to only use it on lead acid batteries only, well I am using AGM batteries in both diesels. What would be the downside of using it on AGM batteries?
Thanks
Ed

 

AGM batteries ARE Lead-Acid batteries.

 

i used my HF 4-1 on my 6.0... thing was rated for 550CCA at the time i got them (newer ones seem to be rated for less).. in addition to the 2 weak batterys in the truck.. my jump box and 2 other "car" batteries i got enough amps to crank her over... been looking to get a bigger one with more amps for use with the truck..

 

Thanks @HT32BSX115 That is what I was thinking. I feel better now.

Now if they said mat (AGM) Vs flooded cell then we could say something.
The bit diff is the charging curve of the AGM over the flooded cell. Right
off the top of my head I can't recall the differences. But there is one and it's
enough that chargers have a different charging curve for them.

 

I would be more apt to go with a capacitor based "booster"...... far safer, you can ship or carry one on an an airplane and they don't "run-a-way" from you at the wrong time!!

(AND chances are, you could easily build one from used Super-Caps bought on ebay)

Not sure the 300A would start a (dead-batt) 6.0L truck anyway,

Isn't there also risk damaging an FICM trying to use a wimpy booster?

 

You might have missed this, he links to his initial thread on it:

300a jump battery wouldnt... you need the engine turning fast enough to drive the oil pump for the injectors.. those mini jumpers would only be good for weakened battery state... for ex coming out of a restaurant to find you left your lights on the whole time you were eating... this sometimes just weakens the battery by killing the surface charge... shut the lights off.. wait 10-20 mins could start, may need a small boost...

running it on a weakened system long term is the problem regarding the FICM.. but jumping it with the box wouldnt hurt it as its not a surge to the system...

 

I did not see his thread. (I did follow his other one though)

Looks like Capacitors might be the way to go.
