OH MAN.
How many basic principles you did break in the procedure?
-You left car to sit for 6 months and did not disconnect battery
-you brought small jump pack to car with dead battery
-you did not disconnect dead battery during cranking and you made no attempt to charge it
-you did not triple pre-glow old diesel.
-the small jump pack barely turn the engine on the 1st try >>> definitely waste of time to try.
In your case you could bring HD jump cables and parallel your wagon. With few minutes of high idle, the W124 battery should show some voltage. If not - the battery needs to be pulled and promptly put in the garbage.
If the dead battery comes back to life, than you can start cranking.

Thats was harsh The thing was that i wanted to show how much power this title booster pack has. Thats why no charing before and etc.

Battery was bad before that's why it left in the car, going to replace it anyway.

Pre glow yah forget that.

Edit anyhow if you got this car running it not problem to go with out battery no need for that. But this car has some kind of problem with air in the diesel so like in this video it starts then die that's normal after that I have to crank it for like 30-60 seconds to get it running even in summer 20+

The new jump battery packs are amazing, but still having old battery shortening the system during cranking is not the best idea. Nickel batteries are rated for the same amp at 1/10 of the weight of traditional led-acid battery.
I have smaller pack, who suppose to give 300 AMP and it will start my 3000W generator on its own, but the thing keeps losing the charge in few months on the shelf.
This is early 606 engine from what I see? They have the maze of plastic fuel tubings that need to be replaced every few years, or air gets inside fuel.

Yess is OM606 W124 250 D 1995 last year for the sedan W124 model i think? Love to drive this car but can not fix the problem with air in diesel. But soon taking in the car to garage again and search for the fix.
