Nowadays, a car is not a luxury, but a means of transportation for many people. Almost every motorist sooner or later faces a problem associated with the battery - a technical product that stores the charge of electric current needed to start the car. Just good to operate the machine is one thing, but when the question is about the technical side, many questions arise even for the most experienced car enthusiasts. The main question of our article: “The battery is dead, what should I do?” Indeed, motorists often encounter this ailment, especially in winter. You leave the entrance, sit in the interior of your favorite car, turn the ignition key, and in response to you frightening engine sounds. It's all about a dead battery. In this case, do not hurry to get nervous and panic. It can still do, and buy a new battery is still unnecessary. In this situation, the main question sounds something like this: "the battery is dead, what should I do?"
You need to follow some rules. First of all, turn off all appliances that consume electricity. Open the hood and carefully inspect the battery terminals. If there are signs of oxidative processes on their surface, this is a sure sign of a dead battery. Before cleaning the terminals, disconnect the wire with the “-” polarity and preferably treat the surface with frost-resistant grease. It is imperative to measure voltage. To start the engine, it is necessary that the voltmeter reads 12V. In winter, you need even more power. If the voltage is not enough, you can try to start the vehicle using the popular method - “from the pusher”. This method is used for cars with a manual gearbox. In the event that the battery is not fully planted, you can wait 15-20 minutes and try to start the car. If the above methods do not help, and the question that sounds like this: “the battery is dead, what should I do?” Remains relevant, there is another common way.
Most motorists, when the battery is completely empty, use a proven method called “lighting”. However, care must be taken during the process itself, as improper connection may explode the battery and damage the car’s central processing unit . The essence of this method is that to “revive” the engine using another machine. It is best to have special wires in the trunk in such a case. So, during the process, the machines should not touch. The engine of the cigarette lighter must be turned off. The terminals are connected in the following order: “+” to “+”, and the “minus” of the dead battery not directly, but through the engine support or cylindrical block. After some time, you need to start a “donor car” and a second car in order. If the car starts, the situation “the battery is dead, what should I do?” Does not threaten you. Do not forget that the terminals will need to be disconnected in the reverse order: first “minus”, and then “plus”.
There is another problem, which sounds something like this: “the battery is frozen, what should I do?” At first glance this is almost impossible, because the electrolyte freezes at minus 70 ° . However, the banal undercharging of the battery due to the oxidation of contacts with the wiring leads to a decrease in charging efficiency. In winter, the viscosity of the electrolyte increases significantly, respectively, electrochemical reactions slow down. Thus, the battery charges longer than usual. At each start-up, the battery is significantly discharged and cannot be fully charged. Naturally, the electrolyte will not freeze, but when the battery is exhausted and sulfuric acid is almost used up, only water remains, which freezes at 0 ° .
As you can see, everything is very simple. So that you won’t be tormented by the expression “the battery is dead, what should I do?”, Monitor the charge of the device and recharge the battery in time. Have a good trip and roads of European quality.
