Small-displacement motorcycles, quad bikes and powersports equipment place demanding requirements on their battery: reliable cold cranking in all weather conditions, resistance to the vibration loads inherent in off-road and urban riding, and the ability to support start-stop cycling where the system demands it. The Varta Powersports AGM Active 12V 3Ah battery (503909005) is engineered specifically for these applications, supplying 50 CCA (EN) from a compact, sealed Absorbent Glass Mat cell.
Manufactured under the Varta Dynamic AGM programme, this battery uses AGM technology in which the electrolyte is permanently suspended within a glass-mat separator. This construction eliminates free acid, making the unit spill-proof and maintenance-free, while delivering the high vibration resistance Varta specifies for its most advanced powersports range. The technology also supports start-stop systems – verify compatibility against the product label before fitment.
The battery occupies a footprint of 113 mm – 70 mm – 87 mm (L × W × H) and weighs 1.5 kg. It is fitted with a Y4 terminal configuration, standard polarity (code 0) and hold-down type B00. Direct factory-authorised cross-references are YTX4L (FA) and TXL4 (FA). IP, MCA and Watt-Hour ratings are not applicable to this model.
This product is available in a range of Varta Powersports AGM Active variants at higher capacities and CCA ratings, including SKUs 510909017, 512905020, 512908021, 512909020, 512918021, 518908027, 518908032, 518909027, 518918032 and 519905027, allowing selection across a broad spectrum of vehicle requirements." The battery is supplied with a 1-year manufacturer's warranty against defects in materials and workmanship. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.
