The possibility of using the battery in cars equipped with a start-stop system.

The start-stop system was created to save fuel and reduce harmful emissions in a modern city, when cars are often forced to stop at traffic lights and in traffic jams. In such cars, a simplified procedure for turning off and starting the engine for short stops is provided: for example, standing at a traffic light, the driver turns off the car by pressing a button, and when the green light turns on, he starts the car by simply pressing the clutch pedal. This provides significant fuel savings, but repeated starts significantly increase the load on the battery — conventional batteries can wear out in a matter of days. Start-stop support allows the battery to work effectively in multiple starts, maintaining its characteristics for a long time.
