518902025 Varta Powersports AGM TX20-BS Battery 12V 18Ah, 1 Year Warranty

Powersports applications demand batteries that deliver consistent cranking performance regardless of ambient temperature or the frequency of charge cycles – a challenge that conventional flooded batteries struggle to meet reliably. The Varta Powersports AGM TX20-BS addresses this directly, providing a sealed, maintenance-free solution engineered for modern motorcycles, scooters and quad bikes that require dependable starting power and structural resilience.

Manufactured under the Varta Dynamic AGM range, this battery employs Absorbent Glass Mat construction in which the electrolyte is immobilised within fibreglass matting. This eliminates free acid, prevents spillage in any orientation and enables a higher charge acceptance rate compared with flooded equivalents. The plate technology is optimised for the repeated shallow discharge cycles characteristic of powersports use, including models with start-stop functionality where the product label confirms compatibility.

The TX20-BS delivers 12V nominal voltage, 18Ah capacity (C20 rating) and 250 Cold Cranking Amps to EN standard. Physical dimensions are 177mm × 88mm – 156mm (L × W × H including terminal). Terminal layout is Y4 with positive polarity designation 1 (positive terminal to the left). Hold-down configuration is B00. Weight is 6.5kg. The battery cross-references directly to TX20-4 and replaces TX20-BS fitments across compatible vehicle applications.

This product is part of a broader Varta Powersports AGM family.
