The arrival of the famous system start/stop it really came to stay, with countless companies adopting this mechanism in their vehicles. After all, it is a technology with even a “basic” purpose that promotes real savings of up to 15% in the average urban consumption of your car.
Batteries for cars with start/stop system are different!
What does it consist of? Well, the start/stop system is responsible for turning off your car’s engine when it is not necessary, for example, at traffic lights and in traffic.
However, an engine without this system is not prepared to turn on and off so many times, as there are changes necessary for the start/stop to be viable. We are here talking about news specific batteries for this purpose, alternators and even special starters.
More advanced and powerful batteries!
In summary, the primary function of your vehicle’s battery is to power the starter, which in turn starts the combustion engine. So far so good, as on average each engine start costs 1-2% of your battery. But if you do it constantly, everything starts to get more complicated.
Therefore, to ensure that the battery does not wear out quickly, two types of batteries were created for cars with a start/stop system:
EFB (Enhanced Flooded Battery);
AGM ( Absorbent Glass Mat).
What are the differences between conventional SLI batteries for EFB and AGM?
SLi or Conventional
In summary, conventional batteries are used for vehicles that do not use a start/stop system, or more advanced systems such as active regeneration. They are used to start the engine and stop the combustion engine on each journey.
EFB batteries are basically the evolution of “conventional” batteries, thus being able to support the entire electrical part of your car and give consecutive starts to the engine during the same journey. They are the most used in “ordinary” cars that use the start/stop system.
AGM batteries are used in vehicles that use more complex systems. For example, energy regeneration, active braking or the electric turbo. For all this to happen, these batteries do not use lead plates in acidic solutions. By the way, here we have a system of glass wool blankets that absorb an aqueous substance and in the end guarantee greater energy efficiency and many more life cycles.
So, now you know that there is a need for more advanced batteries for vehicles with a start/stop system and even for more complex vehicles. Keep this in mind when looking for the most suitable one for your car, following the brand’s recommendations.
