508902012 Varta Powersports AGM T9B-BS Battery 12V 9Ah, 1 Year Warranty

Powersports applications demand a battery that can withstand vibration, repeated deep discharge, and the electrical loads imposed by modern fuel-injected engines with complex ancillary systems. The Varta 508902012 Powersports AGM T9B-BS is a 12V 9Ah absorbed glass mat battery engineered specifically for motorcycles, scooters, and quad bikes that require a compact, maintenance-free power source capable of reliable cold-weather starting.

Manufactured under the Varta Dynamic AGM platform, the T9B-BS uses tightly wound glass mat separators to immobilise the electrolyte, eliminating acid stratification and enabling the battery to recover efficiently from the voltage cycling that characterises stop-start and short-run powersports use. The AGM construction also delivers a higher cold cranking output relative to physical size, rated at 115 CCA (EN), and is resistant to the vibration and shock loads common in off-road and performance applications.

The battery measures 149 mm – 70 mm – 105 mm (L × W × H) and weighs 3.4 kg. It is fitted with Y11 terminals and carries polarity code 1, with hold-down configuration B00. The 508902012 is a direct replacement for T9B-BS and cross-references to T9B-4. It supports start-stop technology where the vehicle manufacturer specifies AGM; verify compatibility against the product label prior to fitment." This battery is available across a range of Varta Powersports AGM capacities and formats to suit varied powersports applications. Please select the appropriate variant for your fitment requirements. The 508902012 is supplied with a 1-year manufacturer warranty covering defects in materials and workmanship under normal operating conditions.
