Product Number: AUX9
Variations
Dual battery systems place considerable demand on auxiliary power management – particularly in vehicles equipped with start-stop technology, where the main battery is dedicated to cranking and a secondary unit must sustain comfort loads during the stop phase. The VARTA Silver Dynamic Auxiliary AGM Battery 9Ah (AUX9) is purpose-built for this role, supplying stable 12V power to electrical components without interrupting core engine functions.
Engineered under the VARTA Dynamic AUX product group (Group 2108), this unit employs Absorbent Glass Mat (AGM) construction. The sealed, maintenance-free design eliminates electrolyte spillage risk and delivers superior charge acceptance and cycle stability compared to conventional flooded batteries – essential qualities in a secondary battery subject to frequent partial-state-of-charge operation.
Fitment data: 151mm (L) × 87mm (W) × 106mm (H including terminal), cold cranking amps 130A (EN), weight 2.87kg. Terminal type Y4, hold-down B00, polarity code 1 (positive terminal right). Cross-references YTX9. Start-stop compatibility is technology-supported – verify against the product label before fitment." A larger auxiliary option is available as AUX14 (PID000138456). Related AGM products include EK091 (PID000137949) and S5AX2 (PID000199756). Supplied with a 1-year manufacturer warranty covering defects in materials and workmanship under normal operating conditions. "Standard delivery: 1–3 working days within UK mainland. 30-day returns.
Dynamic AUX Made for a dual battery system. VARTA® Auxiliary batteries provide electrical components with seamless functionality. This enables an increase in the length of the start-stop moment and supports comfort functions during engine start. Modern cars consume a significant amount of electricity. Therefore, these cars with a combustion engine often come with two batteries: a regular 12 volt starter battery and an auxiliary battery.
Key Feature:Suited for passenger cars, balancing reliable cold-cranking performance with long service life for daily use.
