FA 122 Bosch AGM Motorcycle Battery 12V 5Ah - 0986FA 1220, 1 Year Warranty

Motorcycle batteries operate in demanding conditions short run distances, frequent cold starts, sustained vibration, and extended periods of inactivity all of which accelerate the degradation of conventional flooded cells. The Bosch FA122 is a 12V 5Ah AGM motorcycle battery engineered to meet these specific stresses, supplied under the Bosch S5A AGM range and referenced by Bosch part number 0986FA1220.

Manufactured using Absorbent Glass Mat technology, the FA122 holds electrolyte within a fibreglass separator rather than in free liquid form. This construction eliminates acid stratification, resists damage from mechanical vibration, and supports the repeated charge-discharge cycling associated with urban and off-road motorcycle use. The battery leaves the factory sealed, filled with electrolyte, and fully charged, requiring no pre-activation before fitment. It is also designed to accommodate start-stop functionality where supported verify compatibility against the product label prior to installation.

The FA122 measures 120mm 60mm 130mm (L W H) and weighs 1.9kg. It delivers 75 CCA (EN) cold cranking performance. Terminal polarity should be confirmed directly from the product label before fitment. Cross-reference codes include YB5L-B and 12N5-3B, supporting direct replacement across a range of motorcycle applications.

The FA122 is one of several variants available within the Bosch S5A AGM range at PartsForMachines, including FA100 through FA109, covering differing capacities and dimensional specifications to suit a broad spread of motorcycle platforms.

This battery is covered by a 1 Year Warranty against manufacturing defects, providing assurance of consistent performance throughout its service life.
