518901025 Varta Powersports AGM TX20L-BS Battery 12V 18Ah, 1 Year Warranty

Modern powersports applications demand a battery capable of sustained high-current delivery across demanding terrain and variable ambient temperatures. The Varta Powersports AGM TX20L-BS (SKU 518901025) is a sealed, maintenance-free absorbed glass mat battery engineered specifically for motorcycles, scooters and quad bikes operating in conditions where a conventional flooded cell would be inadequate.

Manufactured under the Varta Dynamic AGM range, this battery employs absorbent glass mat technology in which the electrolyte is immobilised within a fibreglass separator. This construction eliminates acid stratification, resists vibration damage, and delivers a stable 250 CCA (EN) cold cranking output with a rated capacity of 18Ah at the C20 rate. The sealed, valve-regulated design prevents electrolyte loss and permits installation in non-upright orientations. The technology also supports start-stop functionality where fitted – verify compatibility against the product label prior to installation.

The battery measures 177 mm (L) × 88 mm (W) × 156 mm (H inc. terminal) and weighs 6.5 kg. It uses a Y4 terminal configuration with standard polarity (positive left, terminal placement code 0) and a B00 hold-down base. The cross-reference code for this unit is TX20L-4, making it a direct replacement for applications listed under that designation. Rated at 12 V nominal.

This product is available across a range of Varta Powersports AGM variants by capacity and terminal arrangement, including SKUs 503909005, 510909017, 512905020, 512908021, 512909020, 512918021, 518908027, 518908032, 518909027, and 518918032, allowing selection of the correct fitment for the specific application." This battery is covered by a 1-year manufacturer warranty against defects in materials and workmanship under normal operating conditions.
