Signs that the battery is dead
Before finding out what to do if the battery in the car is dead, you need to make sure that the battery is really no longer a source of energy.

The engine cranks several times, and then begins to start;
starter sounds very dull, as if it has lost power;
The color of the indicators on the dashboard becomes muffled, also it disappears regularly.
It should be noted that the last point applies exclusively to outdated cars whose dashboard consists of conventional bulbs. Modern LED lights can shine brightly, but the engine still will not start.
Experienced motorists always know what to do if the battery is dead. They have a good feel for their car, so with the onset of fall in the construction of the vehicle will have a brand new battery. If you missed such signs, and some winter morning the battery died, you will definitely need help.

Another thing is if the battery died, which was bought somewhere at the bazaar and without certificates. In such case it is not surprising that the driver will have to deal with the consequences of ill-considered decision.
It is better not to save money on the battery, because otherwise you will have to learn how to start the car if the battery is dead.
How to start the car if the battery is dead
Let’s move on to the question you are interested in: what a driver should do if the battery in the car is dead. There are several ways to start the car to go about your business and buy a new battery. They should include:
Starting the internal combustion engine with the help of a special starting device (ROM);
Starting with a pusher or a tow truck – not suitable if you want to know how to start the car automatic, if the battery died;
classic “cigarette lightering” from another battery.
It is important to know that these methods are not universal for every car. For example, it is better not to start the automatic transmission from a pusher or a tow truck.
You have a dead battery, what to do and which of the above methods to choose? The best option would be to use a ROM. This is really a universal way for any car. However, it is only possible if you have the ROM itself, so you should take care of its purchase in advance. It is also important that there is a 220 watt power supply nearby. Otherwise, the starter will be useless if the battery in the car is dead.
Not all car owners have their own garage with quality wiring where a ROM could easily be used. Even if you have one, don’t apply an increased charge. Certainly, this way you will charge the battery for a long time, but seriously reduce its service life.
The second solution, how to start the car if the battery is dead, is suitable only for mechanics. Do not use it for automatic transmission. It needs electricity to work, while a normal hydraulic automatic can work without it. In addition, this option can damage the onboard network and built-in electronics, because of which you will definitely have to visit the nearest service station.
If the battery is dead in the automatic, how to start the car – a question that no longer requires an answer. In the absence of ROM, you can only use the cigarette lighter from another battery.
