Thanks to the use of EFB technology, the Exide EL550 battery offers higher starting performance in low temperatures and is more resistant to discharging, significantly extending its lifespan compared to conventional batteries. EFB technology introduces improvements at the material and design level, thereby enabling better handling of intense charging and discharging cycles, which are common in vehicles with start-stop systems and those abundant in onboard electrical devices. Its capacity is 55 Ah, and the maximum starting current is 540 amperes. The positive pole (+) is located on the right side of the battery, looking from the terminal side. This is the most common layout in the United Kingdom.
