Empty battery, how to start a car?

Baterry in a car.

Sometimes we have an empty battery in the car and do not know what we do. When someone in the parking lot has a cable.
how to connect the battery from the car? It is very easy.
I noticed that not everyone knows how to do it. I decided to write about it.

The black clamp

The red clamp

If the battery is empty you can not do a few things.
Red and black clamps cannot be connected together. Never allow the black and red clams to touch the same metal objekt.

Battery

You should connect the red (+) positive pole baterry terminal to a other car and later to the red (+) positive pole baterry.
We should connect the black (-) clamp to a colleague.
The other end the black (-) clamp to non moving metal part of the engine. Other vehicle start, than our vehicle start.

We disconnect in reverse order.
1. We - the black (-)
2. Other car - the black (-)
3. We - red (+)
4. Other car (+)
