Product Number: AUX14
Variations
Auxiliary batteries in dual battery systems must maintain a stable supply to comfort and stop-start functions without drawing on the primary cranking battery – a demand that requires dedicated AGM technology rather than a conventional lead-acid unit. The VARTA AUX14 Silver Dynamic Auxiliary AGM battery is purpose-built for exactly this role, carrying the VARTA Product Group 2108 designation and forming part of the Dynamic AUX range engineered for secondary battery positions in modern vehicles.
Manufactured to VARTA's AGM (Absorbent Glass Mat) specification, the AUX14 uses a sealed, recombinant construction in which the electrolyte is held within a fibreglass mat rather than free liquid. This design provides high cycle stability, resistance to vibration, and zero-maintenance operation – qualities essential in auxiliary positions where the battery may undergo frequent partial discharge during extended stop-start events and where it must support electrical comfort loads such as climate control and infotainment during engine-off periods.
The AUX14 delivers 12V nominal voltage, 13Ah capacity, and 200A cold cranking amps (EN). Physical dimensions are 150mm (L) × 87mm (W) × 146mm (H including terminal). Terminal layout is Y4 with polarity code 1 (positive terminal right). Hold-down type is B00. Weight is 4.6 kg. Cross-reference: YTX14. Start-stop compatibility is supported by the AGM technology; verify final fitment against the vehicle manufacturer's label.
A smaller auxiliary variant, the AUX9 (SKU: AUX9), is available within the same Dynamic AUX range for applications specifying a lower capacity secondary battery. The AUX14 is supplied with a 1-year manufacturer's warranty against defects in materials and workmanship. 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.

• Product Group: 2108, VARTA Dynamic AUX, purpose-built for dependable performance in the intended application.
• Engineered as an AGM Battery, delivering consistent, reliable operation in daily use.
• Manufactured by VARTA, a trusted name in automotive batteries, known for dependable quality.
• Weighs 4.6 kg (10.1 lb) balancing power and manageability for easier installation and handling.
• OEM-style fitment supports straightforward replacement and proper mounting.
• 12V system compatible with standard vehicle electrical requirements.
Compatibility:
Suited for passenger cars, balancing reliable cold-cranking performance with long service life for daily use.
Uses:
• Restores dependable starting for vehicles that need consistent, everyday performance.
• Suited to AGM Battery applications, delivering steady operation in daily driving conditions.
• Supports stable power delivery for ignition, lighting, and onboard electronics.
• Performs reliably across short trips and longer runs where dependable restarts are essential.

A. The AUX14 is a 12V auxiliary AGM battery with a rated capacity of 13Ah at the C20 discharge rate and 200A cold cranking amps (EN standard).
A. The AUX14 measures 150mm in length, 87mm in width, and 146mm in height including the terminal. It weighs 4.6 kg.
A. The AUX14 uses a Y4 terminal configuration with polarity code 1, meaning the positive terminal is positioned on the right-hand side. The hold-down type is B00.
A. Yes. The AGM construction of the AUX14 is designed to support start-stop functionality in dual battery systems. You should always verify final compatibility against the vehicle manufacturer's label and specification.
A. Product Group 2108 is VARTA's internal classification for the Dynamic AUX range, indicating the battery is purpose-built for auxiliary positions in dual battery systems rather than as a primary cranking or deep-cycle unit.
A. The AUX14 cross-references to YTX14. Buyers sourcing replacements against Yuasa YTX14-BS or Lucas YTX14-BS part numbers should verify dimensions and terminal layout before fitting.
A. Yes. The AUX9 (SKU: AUX9) is a smaller capacity auxiliary AGM battery within the same VARTA Dynamic AUX range, suitable for applications specifying a lower secondary battery capacity.
A. The AUX14 is supplied with a 1-year warranty covering defects in materials and workmanship under normal operating conditions.
A. Standard delivery is 1–3 working days within UK mainland. A 30-day returns policy applies.
A. An auxiliary battery is installed alongside the primary starter battery in dual battery systems. It supplies electrical comfort loads — such as climate control and infotainment — and helps extend the stop-start phase, without depleting the main cranking battery. AGM technology provides the cycle stability required for this repeated partial-discharge duty.
A. A 30-day returns policy applies.
