Thanks to the use of EFB technology, the Bosch S4 E11 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 80 Ah, and the maximum starting current is 730 amperes. The pole layout is 0 – the positive is on the right side.
