Product Number: AUX1

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) × 175mm (W) × 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. "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.

A. The battery operates at 12V with a capacity of 35Ah rated at the C20 discharge rate. Its Cold Cranking Amps (EN) rating is 520A.
A. The battery measures 212mm in length, 175mm in width, and 140mm in height including the terminal. It weighs 10.75kg.
A. The AGM technology used in the AUX1 supports start-stop system operation. However, compatibility depends on your specific vehicle's battery management system and the requirements set by the manufacturer. Always verify suitability against the product label and your vehicle's documentation before installation.
A. No IP rating is specified for the Varta AUX1. It is intended for automotive auxiliary applications within enclosed battery compartments. It is not assessed or rated for marine or fully exposed outdoor use.
A. The Varta manufacturer part number is 535106052. The PartsForMachines SKU is AUX1. No additional cross-reference codes are listed for this product.
A. The Varta AUX1 is supplied with a 1-year warranty covering manufacturing defects under normal operating and installation conditions. The warranty does not cover damage resulting from incorrect fitment, misuse, or installation in an incompatible application.
A. Standard delivery is 1–3 working days to UK mainland addresses. A 30-day returns policy applies. For delivery to non-mainland UK locations or international destinations, please contact PartsForMachines directly prior to ordering.
A. The AUX1 uses Terminal Type 1, with Polarity 0 — meaning the positive terminal is positioned on the left when viewed from the front. The hold-down specification is B13. Confirm these details against your vehicle's battery tray and cabling before fitment.
A. The AUX1 uses Absorbent Glass Mat (AGM) technology, in which the electrolyte is absorbed into glass fibre separators rather than remaining in free liquid form. This construction provides high cycle stability under repeated partial discharge, low self-discharge rates, and strong vibration resistance — all critical requirements for a battery operating continuously in a secondary role.
A. The Varta AUX1 is a dedicated auxiliary battery designed for use in dual battery systems. It supplies power to electrical comfort functions — such as climate control, infotainment, and lighting — during engine-off or start-stop events, allowing the main cranking battery to focus on engine starting.
