There can be several reasons why a car battery is dead, and it doesn't matter whether it was working or not.

What are the main reasons:

1. If the car has not been used for a long time

The battery often runs down, even if the car hasn't been driven for a long time, and inexperienced drivers are often surprised - "Why?". And the reasons can be quite common, and are often created by the owners themselves. The main reasons for a dead battery in an unused car can be considered:

2. The car sits for many days with the alarm or central locking on

Even though the alarm is on, it consumes a small amount of electricity, but if you leave the car with the alarm on for a few weeks, it will eventually drain the battery. The same is true for the central locking, as on some models the locking function “on” means it is under constant electrical voltage;

There is a leak somewhere in the circuit. If there is a small current leak in the car's electrical circuit through the wiring or electronic systems, which the owner does not feel while driving, then during long idling this leak often leads to battery drain;

3. The ambient temperature is too low

If the car is not used for a long time in the winter and does not work in the cold, then you cannot count on a well-charged battery. In cold weather, without periodic recharging, the battery tends to discharge much faster than in the summer.

4. Defective battery

Even a fully functional battery is likely to lose its charge, new up to 1%, used up to 3%. And if the battery has these signs, then its discharge should not surprise you:

  • If the electrolyte leaks. The electrolyte has a higher density in the lower part than in the upper part;
  • The lead pins are covered with oxide. If this happens, then they should be cleaned with very fine sandpaper;
  • Plate sulfation. If the battery is not charged for a long time or the electrolyte level is below the minimum level, the plates can become sulfated, i.e. become covered with lead crystals. If the sulfation is still insignificant, then it can be eliminated by several charge-discharge cycles;
  • Short circuit in the plates. This can happen, for example, if the battery is shaken strongly if it is not properly secured;
  • Damage to the battery. If the damage is minor (small cracks, chips, etc.), then they can be repaired using a good adhesive.

5. Unplugged devices

Some careless drivers, when getting out of the car, forget to turn off some devices that slowly but surely "drain" the battery. These can be side lights, interior lighting, radio, video recorder or any other device that is connected to the cigarette lighter.

If the “consumer” remains turned on for several days in a row (for example, when the owner has flown away and left the car in the airport parking lot), then relying on a charged battery is, to say the least, naive.

6. Faulty wiring or electrical equipment

A common reason why the battery charge level often "drops" is malfunctions in the car's electrical wiring or electrical appliances.

In this case, it is necessary to check each device with a multimeter, but it is better to contact the specialists of roadside assistance in Sofia – Naydenovi Auto Ltd.who will do everything professionally.

7. Poor engine condition

Another reason for the rapid discharge of the battery is the poor technical condition of the engine. Often, car owners who have not performed engine maintenance for a long time try to start the car by holding the starter for more than a minute (and so on several times in a row). These actions most quickly deprive the battery of charge, since the maximum “amount” of current is consumed when starting the engine.
