FA 105 Bosch AGM Motorcycle Battery 12V 12Ah - 0986FA 1050, 1 Year Warranty

Motorcycle batteries must endure vibration, repeated short-run discharge cycles, and the demands of modern start-stop ignition systems conditions that standard lead-acid chemistry handles poorly. The Bosch S5A AGM (FA105) is engineered specifically to meet these stresses, delivering dependable cold-weather starting and stable power output across a wide range of two-wheel applications.

Manufactured in Europe by Bosch, the S5A range uses Absorbent Glass Mat (AGM) technology in which the electrolyte is fully absorbed into a glass fibre separator. This construction eliminates free acid, making the battery spill-proof and maintenance-free. The sealed, factory-activated design arrives filled, fully charged, and ready for immediate fitment. AGM construction also provides enhanced resistance to vibration and deep-discharge cycling, making the battery equally suited to commuter use, off-road riding, and motorsport applications.

The FA105 carries a 12V nominal voltage and a 12Ah capacity (C20 rating), with a Cold Cranking Amperage of 210A (EN). Physical dimensions are 133mm 90mm 164mm (L W H), and the battery weighs 4.4kg. Polarity configuration should be confirmed against the product label prior to installation. This unit cross-references directly to YTX14AHL-BS, YB14L-A2, YB14L-B2, and 12N14-3A. The AGM technology supports start-stop functionality verify compatibility against the product label. Bosch part number: 0986FA1050.

The FA105 is part of the Bosch S5A AGM motorcycle battery range, which is available in multiple capacities to suit a broad spectrum of machines. Related variants in this series include FA100 through FA110. Compatible alternatives in AGM format are available under SKUs ETX14AHL-BS and ETX14AH-BS.

This battery is covered by a 1-year warranty, providing documented assurance of performance and build quality under normal operating conditions.
