Why does the battery run low

Most passenger cars are equipped with a 12 watt battery. Almost all models of batteries are the same, they differ in power parameter. The ordinary driver is not interested in chemical processes and other details, it is important for him that the battery does not let him down at an important moment.

When buying a car, pay attention to the date of issue of the battery and the date of installation, the charge level. Even in branded salons there is a risk to get on the latest model of charging.

Common Causes of Fast Battery Discharge

Even if the battery is discharged, it does not mean that the battery is already out of order. First, do the following:

• check the electrolyte level;
• check the output voltage: a good parameter is from 11 to 13.2 V.

If the wiring is in good condition, the terminals are not oxidized, they sit tightly, then we are looking for a problem in the electrical equipment:

• incorrect installation of additional equipment;
• Too powerful music or alarm, especially satellite;
• generator failure: charging relay, brush and starter.

Of course, it’s best to turn to specialists if you don’t understand at all in this matter, and if you have an on-board computer installed in your car, you need to start with computer diagnostics.

Remember that accelerating the discharge of the battery also contributes to the fact that you will leave a burning light or not turn off the radio.

How to check the battery

Before you begin to solve the problem, you need to check the car battery to determine if there are external cracks, the presence of salts. If the battery has plugs, check the electrolyte, the color of the eye.

The main element is the load fork. With a fully charged battery, it will show a value of 12.5-13 V. Please note that the average lifespan is 3 years and most models cannot be repaired. Also consider that in cold weather the load on the battery will be much higher.

For beginners, it is recommended to contact specialists. Do not forget about the routine inspection at the workshop to timely identify possible problems and quickly solve them. You can buy a battery tester on 130.com.ua with delivery to Kharkov, Odessa, Kiev and in Ukraine.
