The role of car batteries in modern cars
Usually the life of the car battery is indicated around three to five years old. AGM batteries in particular have a hard time, even if they tolerate it better cyclic load, on the other hand, the control unit treats them quite thoughtlessly. You might be thinking, so what’s the problem if they don’t care about period that much? It mainly concerns stop-start systemwhich sometimes forces the car even with a cold engine start several times during a short trip. So instead of cycling, i.e. charging and discharging, the car battery is permanently discharged. The engine starts, but its voltage is about 12.3V, which is not good for him and on the electrodes sulphation occurs.
Charging isn’t what it used to be
However, a modern car can also destroy a flooded classic car battery within two years. Due to lower consumption, the alternator does not always charge, but only when the control unit allows it. And it’s mostly set up to have a car lowest possible emissions. The car starts, the air conditioning, heated windows, heated steering wheel and heated seats come on, but everything runs on battery energy, because the alternator is not charging at that moment due to emissions. Starts only at higher revs, typically in motorway traffic, but in town only when the car battery is already charged really exhausted and there is a risk that its energy will not be enough for the next start. And once the tension is at least somewhat sufficient, charging stops. The driver then stops the car for a week, p battery not charged enoughthen lead sulphate is formed again on the electrodes.
If you have an older car without a stop-start system that charges pretty much all the time and at a constant voltage, theoretically your battery should last longer. If you want to extend the life of your car battery, we recommend you to buy it strengthened (EFB), which has thicker electrode plates and is more durable. Obviously you need to charge it regularly so that the voltage doesn’t drop below 12.4V. EFB batteries are virtually identical to those that automakers fit into their original production cars, which explains why, for example, a single octave car battery lasted more than 10 years.
Car battery life can be easily extended
The general advice on how to extend the life of a car battery is that you have to recharge it yourself, don’t rely on the car. Once every 14 days to a month, just plug the charger into the battery and leave it fully charge the battery. if you have EFB batteries, so with proper care it will have no problem lasting that decade as well. The problem is not so much in the car batteries (if we leave aside the really cheaper ones), but in the cars that the manufacturers build mainly in such a way that during operation generated as few emissions as possible. The fact that they dispose of car batteries one by one is not very environmentally friendly, but unfortunately this is not the norm it neither traces nor establishes.
