The process of starting the starter from a screwdriver battery
You need to make 2 jumpers from a thick wire. For less resistance, they should be as short as possible, 35–50 cm. The insulation at the ends of the jumpers is stripped to 3 cm. On one side, they are bent to tightly engage the contacts on the screwdriver battery.
The opposite ends of the jumpers are connected to the terminals on the car battery, always observing the polarity. After this, the car starts and the wires are removed. If there is no thick enough wire, then sufficient starting current will not flow through it and nothing will work. Then you need to connect with thin jumpers and wait. In this case, the car battery will be charged from the screwdriver battery.
