Motorcycle batteries face demanding operating conditions frequent cold starts, prolonged vibration, and short-distance duty cycles that prevent full recharge. The Bosch S5A AGM (FA111) is engineered to meet these challenges, delivering 12V and 4Ah capacity with 70 CCA (EN) in a sealed, factory-activated format that is ready to install straight from the box.
Manufactured in Europe, this battery uses Absorbent Glass Mat (AGM) technology in which the electrolyte is suspended within a glass-fibre mat rather than held as free liquid. This construction eliminates acid stratification, improves vibration resistance, and supports the deep discharge cycles typical of stop-start urban riding, off-road use, and motorsport applications. The sealed design requires no maintenance and prevents acid spillage in any mounting orientation." The FA111 measures 113mm (L) 70mm (W) 105mm (H inc. terminal) and weighs 1.8 kg. Terminal polarity should be confirmed against the product label prior to fitment. This unit crosses directly to YTX5L-BS and YTX5L references. The technology supports start-stop systems verify compatibility against the product label before installation. "This battery is part of the Bosch S5A AGM range. Related variants within the FA series include FA100 through FA109. Compatible alternatives include ETX5L-BS, AGM12-5, LTS4LB, LTS4LBS, and LTX5LBS." The FA111 is supplied with a 1-year warranty covering defects in materials and workmanship under everyday operating conditions. "Standard delivery: 13 working days within UK mainland. 30-day returns.
