No jump pack is going to start our diesels with a dead battery connected.
11V is dead.

12V is dead…

12.3 is jumpable… 12.6 is nearly full…

The lithium packs that weigh 2lbs plus will work if they have a charge up feature…

I agree with everybody else, charge or replace the battery.

Jump packs are great, and the 1200A models that weigh a ton will start, but ya gotta let it charge the battery up.
