Motorcycle batteries operate under demanding conditions frequent cold starts, sustained vibration, and the deep discharge cycles associated with short urban commutes or high-intensity off-road use. The Bosch S5A AGM FA100 is engineered to address these challenges directly, delivering dependable 12V power in a compact, sealed format suited to a wide range of small-displacement motorcycles and powersports applications.
Manufactured in Europe, this battery employs Absorbent Glass Mat (AGM) technology, in which the electrolyte is suspended within glass fibre separators rather than held in free liquid form. This construction eliminates acid stratification, reduces internal resistance, and confers genuine resistance to vibration damage a significant advantage in motorcycle applications where road shock and engine vibration are constants. The battery is factory-activated, arriving filled, fully charged, and sealed, requiring no pre-activation prior to fitment." The FA100 measures 120 mm 70 mm 92 mm (L W H) and has a rated capacity of 4Ah (C20) with a Cold Cranking Amp rating of 55A (EN). Polarity should be confirmed from the product label prior to installation. This unit crosses to YB4L-B and YTB4L reference codes. Weight is 1.59 kg. The AGM technology within this product supports start-stop system operation verify compatibility with the product label before fitting. "The FA100 is one unit within the Bosch S5A AGM motorcycle battery range. Related variants include FA101 through FA110, covering differing capacities and dimensional specifications for alternative applications.
This battery is supplied with a 1-year warranty, providing assurance of product integrity under normal operating conditions.
