FA 103 Bosch AGM Motorcycle Battery 12V 9Ah - 0986FA 1030, 1 Year Warranty

Motorcycle electrical systems demand a battery that can endure repeated short-trip cycling, high-vibration environments, and the load demands of modern engine management systems. The Bosch S5A AGM 12V 9Ah Motorcycle Battery (FA103) addresses these requirements with absorbent glass mat construction that immobilises the electrolyte, eliminating acid stratification and improving resilience against the discharge-recharge cycles typical of commuter and sports riding.

Manufactured in Europe, the Bosch S5A range is sealed and factory-activated: the battery arrives filled with electrolyte, fully charged, and ready for immediate installation with no pre-conditioning required. The AGM technology is designed to support start-stop functionality where fitted confirm compatibility by checking the product label before installation.

The FA103 measures 135 mm 75 mm 139 mm (L W H) and weighs 3.05 kg. Cold cranking performance is rated at 100 CCA (EN). Capacity is 9Ah (C20). Polarity should be verified against the product label prior to fitting. Cross-reference codes include YB9-B, YTB9, and 12N9-4B-1 always confirm fitment against your vehicle's specification.

The Bosch S5A AGM range extends across multiple capacities. Related variants available at PartsForMachines include FA100, FA101, FA102, FA104, FA105, FA106, FA107, FA108, FA109, and FA110, covering a broad range of motorcycle applications.
