Motorcycle batteries face demanding conditions frequent short trips, high-vibration environments, and in modern machines, the additional strain of start-stop systems. The Bosch S5A AGM (FA112) is a sealed, factory-activated 12V 12Ah battery engineered to meet these challenges across a wide range of motorcycles, scooters, and off-road applications.
Manufactured in Europe, the Bosch S5A series uses Absorbent Glass Mat (AGM) technology, in which the electrolyte is immobilised within fibreglass matting. This construction eliminates free acid, making the battery spill-proof and maintenance-free. AGM cells deliver superior resilience to deep discharge and mechanical vibration compared with conventional flooded designs, and the technology supports start-stop functionality verify compatibility with the product label prior to fitment.
The FA112 measures 134mm 81mm 160mm (L W H) and weighs 3.88 kg. It delivers 125 Cold Cranking Amps (EN) at 12V with a 12Ah (C20) capacity. The battery arrives sealed and fully charged, ready for immediate installation. Terminal polarity should be confirmed via the product label before fitment. Cross-reference codes: YB12AL-A, YB12AL-A2. Bosch part number: 0986FA1120.
The FA112 is one of ten variants within this Bosch S5A AGM range, spanning SKUs FA100 through FA109, covering a broad spread of capacities and fitments for different motorcycle platforms." This battery is supplied with a 1-year warranty covering defects in materials and workmanship. "Standard delivery: 13 working days within UK mainland. 30-day returns.
