The Exide EL604 battery utilizes advanced EFB (Enhanced Flooded Battery) technology, which represents an evolution of traditional lead-acid batteries. EFB technology increases the battery’s resistance to deep discharges and frequent charging cycles, which is particularly important in vehicles that use start-stop systems and those equipped with numerous electrical devices operating even when the engine is off. The basic parameters of the battery are 60 Ah of capacity and 520 A of starting current. The positive is on the right side.
