They are a fundamental component but one that the technology increasingly used in cars affects directly and sometimes if they are not in good condition, they fail. According to specialist Clarios, there are six causes that cause problems:
Hot summer that causes an increase in temperature.
A profusion of increasingly demanding electrical systems in the car.
Vehicles stopped for two weeks due to confinement or because they are in second homes.
Aging of the automobile fleet.
Increase in short trips.
On the other hand, the Norauto auto center network points out that high temperatures cause the interior of the battery to dry more easily, to which is added that if it is close to its useful life, the chances of it failing increase. In fact, it is one of the components that causes the most problems in summer.
On average, it lasts about four years, but high temperatures can lead to faster aging. To this are added the short trips, as has been indicated, so it is advisable to check their condition and also the charging system (alternator) to see if it presents any type of anomaly.
In fact, just last summer and in the midst of the pandemic, Norauto performed more than 4,500 battery replacement and installation services at home, an option that more and more drivers are turning to.
What to do if the car battery fails?
1) Starter clamps: If the car does not start and there is the possibility of having another vehicle, clamps can be used, connecting the positive terminals with positive and negative with negative. In addition, the battery that tries to start another car must be equal to or greater than that of the damaged one. It is advisable to review it later in a specialized center.
2) Starter or booster: It performs the same function as the clamps but has a protection system to avoid possible damage.
3) Change it: It is the best option if you are already quite old, more than five. In this case, care must be taken not to cause a short circuit that could damage the car's electronics. In addition, in some cases, it is necessary to reprogram the energy management system. In more modern cars it is more advisable to go to a specialist.
4) Start-Stop system: If the car has an automatic start and stops system, the battery changes, since in this case, they are specific, with more capacity and more power. They can be of the EFB (enhanced flooded battery) or AGM (absorbent glass mat) type depending on the type of car and the energy required.
If the battery of cars with start & stop is discharged, the clamps cannot be connected to another that does not have this technology, since the system itself for connecting the clamps is different.
In fact, for the change in this type of car, it is necessary to connect electronic diagnosis equipment to configure the electronic control units. If the change is made without the equipment, the charging circuit will not work properly.
5) Vehicle stopped for a long time: If the car is not going to be used, it is advisable to use a battery maintainer that is plugged into the network or to start it every so often. In this way, we prevent it from being downloaded.
