FA 126 Bosch AGM Motorcycle Battery 12V 18Ah - 0986FA 1260, 1 Year Warranty

Motorcycle batteries must endure relentless vibration, frequent cold starts, and the electrical demands of modern ancillaries conditions that expose the limitations of conventional flooded designs. The Bosch S5A AGM FA126 is engineered to meet these demands, delivering 12V and 18Ah of capacity within a sealed, maintenance-free construction suited to a wide range of middleweight and heavyweight motorcycles.

Manufactured in Europe under Bosch's S5A AGM programme, the FA126 uses absorbent glass mat technology in which the electrolyte is suspended within a fibreglass mat separator. This eliminates acid stratification, suppresses the effects of vibration fatigue, and supports the deep discharge cycles associated with short-distance urban riding as well as the sustained electrical loads of motorsport and off-road applications. The battery is sealed, factory activated, filled with acid, and fully charged at point of manufacture requiring no pre-installation preparation.

The FA126 measures 176 mm 89 mm 154 mm (L W H) and weighs 6.55 kg. Cold cranking performance is rated at 310 A (EN). Polarity should be confirmed against the product label prior to installation. This unit cross-references against YTX20H-BS, YTX20-BS, and YTX20 references. The AGM technology supports start-stop systems; verify compatibility with the product label before fitment.

The FA126 is one of ten variants within this Bosch S5A AGM listing range, spanning SKUs FA100 through FA109.
