Well, I have no idea how but I managed to solve the problem with screw and the btr battery. For me there were two possible solution that could possibly trigger the dialogue option:
I did the quest for Voronin in exchange to get back my confiscated stuff from the mean duty officer after the flashdrive hunting. (you have to get the crossbow to get in the duty base. Just jump over the guard in the freedom base and shoot off the padlock, I didn't test it thoroughly but I think it is recommended to gain the trust )of them so their attitude will be friend, that way it is unlikely they will ring the alarm for stealing the weapon and they just won't give a sh*t)
The other possible solution (which I recommend to try first) is that you have to have the artifact "battery" along with the car battery. I had 4 in my inventory and later I noticed I lost 3 after I handed over the car battery) So there might be a f* up with the translation.
Before these two actions the dialogue option wouldn't show up, but after it did.
