    Dual battery systems place significant electrical demands on auxiliary power sources, requiring a dedicated unit capable of supporting comfort functions and extended start-stop cycles without drawing on the main cranking battery. The Varta Silver Dynamic Auxiliary Battery 12V 35Ah (Part No. 535106052) is engineered specifically for this role, operating as a secondary battery within vehicles equipped with advanced energy management systems. Manufactured under the Varta Dynamic AUX programme, this battery uses Absorbent Glass Mat (AGM) technology, which immobilises the electrolyte within glass fibre separators. This construction delivers high cycle stability, low self-discharge, and resistance to vibration - all essential characteristics for an auxiliary unit subjected to frequent partial-state-of-charge operation. The battery carries a Cold Cranking Amps (EN) rating of 520A and a capacity of 35Ah (C20), providing sustained output to electrical consumers during engine-off periods. Dimensions are 212mm (L) x- 175mm (W) x- 140mm (H including terminal), with a weight of 10.75kg. The battery features Terminal Type 1, Hold-Down B13, and Polarity 0 (positive terminal left). It is assigned to Product Group 2108. No direct cross-reference codes are listed; compatibility with start-stop systems is supported by the AGM technology - verify suitability against the product label before fitment." No variant configurations are available for this SKU. This battery is supplied with a 1-year warranty covering manufacturing defects under normal operating conditions. " .
