Owners manual says you can jump it like any other system. Cables, portable, etc. Hearing horror stories about jeeps not startingI've read that such devices may not provide adequate current for the JL because jumping it with them is first, as described above, about reaching a minimum charge in both batteries before cranking can be attempted, much less succeed.
But couldn't both this wait time AND the inability of such devices to adequately jump the JL be addressed (maybe this is more academic than practical as there are other techniques) by disconnecting the leads to the main battery, and connecting the original poster's "powerbank" to these leads?
I ask because wouldn't the above charge only the smaller battery: faster than charging both, and give it enough current to power the start relay connected to it, to signal the engine starter to fire?
I've got this right, while the engine starter is connected to the main (and here disconnected/dead) main battery, it's backed up by the ESS battery---e.g. people being able to start their JLs with the ESS battery only. The ESS battery could devote its power in this example to the engine crank rather than split it with also charging the main battery(??)
Once the JL's turned over, the "powerbank" could be packed up, and the battery terminals reconnect to the main battery for the alternator to charge both batteries(??)
Please correct this if wrong: I want to spread fact and understand. : - )
Yes and no. The manual suggests a waiting period between cable hook up and crank, I guess for the charging discussed above. This differs from other vehicles and may help explain why powerpacks designed more for high power for short durations prove inadequate here(??)Owners manual says you can jump it like any other system.

Thanks in advance for searching for us!There are probably 5 or more forum threads that address what one will will face when trying to jump start a JL.
A forum search will bring up the threads if anyone wants to learn more in regard to this.
@allieboyThanks in advance for searching for us!

Because I was kidding.....good grief
When you finish searching...change my oil@OldGuyNewJeep
Fruck that .. that requires minimal effort to do.. Can you please do the search for me.....
I like this post...I'll tell you why.
