Bosch Automotive Starterbatterie

In AGM technology (Absorbent Glass Mat), special fiberglass mats are placed between the lead plates of the battery, binding the acid. This results in a low internal resistance and a rapid reaction between the acid and plate material, allowing the battery to provide larger energy masses. Thanks to AGM technology, Bosch's S5-AX auxiliary battery delivers reliable performance even during high load peaks. The 12V onboard network is stabilized, and fuel-saving start-stop phases can be extended, as a secure start is ensured even at extreme temperatures and while running comfort functions. With up to four times the cycle stability compared to conventional starter batteries, Bosch's auxiliary batteries also achieve a longer lifespan. The optimized grid design further ensures excellent charge absorption and consistently high starting power and corrosion resistance. Additionally, the S5-AX battery is completely maintenance-free due to its special lid design.
