504909008 Varta Powersports AGM Active Battery 12V 4Ah, 1 Year Warranty

Powersports applications demand a battery capable of withstanding sustained vibration, frequent deep cycling, and exposure to demanding environmental conditions – requirements that conventional flooded batteries often fail to meet reliably. The Varta Powersports AGM Active 12V 4Ah battery (SKU: 504909008) is engineered specifically to address these challenges, delivering dependable cranking performance and reserve capacity for motorcycles, ATVs, personal watercraft, and leisure vehicles.

Manufactured under Varta's Dynamic AGM product group (FUNSTART AGM, Product Group 2185), this battery employs Absorbed Glass Mat technology in which the electrolyte is permanently suspended within a fibreglass mat separator. This construction eliminates free acid, provides superior vibration resistance, and enables maintenance-free, sealed operation throughout the battery's service life. The AGM design also supports applications where start-stop technology is specified – verify compatibility with the product label before fitment.

The 504909008 measures 113mm (L) × 70mm (W) × 105mm (H inc. terminal) and weighs 1.92 kg. It delivers 80 CCA (EN) from a 4Ah (C20) capacity at 12V. Terminal configuration is Y4 with polarity code 0 and hold-down type B00. This unit cross-references directly to YTX5L (FA) and TXL5 (FA), making it a compatible replacement across a wide range of powersports OEM specifications.
