The Bosch S5 A battery with AGM technology provides sufficient energy for frequent stops and starts, reliably powering electronic consumers during the stop phase. AGM technology (Absorbent Glass Mat): acid bound in micro-glass fiber mats allows for higher energy masses to pass through. It offers a longer lifespan and up to four times the cycle stability compared to conventional starter batteries. Consistent power is maintained even during short trips, stop-and-go traffic, or high consumption while stationary. Excellent charge acceptance and starting power with a high number of electrical consumers. Completely maintenance-free and leak-proof.
