The VARTA Dynamic AUX AUX14 (513106020) is a premium secondary automotive battery engineered in Germany to provide seamless functionality for modern, high-demand dual-battery systems. As contemporary vehicles consume a significant amount of electricity, many combustion engines operate with both a primary starter battery and a dedicated auxiliary unit. The AUX14 is specifically designed to support advanced cabin comfort features during engine starts and safely extend the duration of Start-Stop sequences. Housed in a compact YTX14 case size, its specialised internal engineering satisfies strict original equipment (OE) manufacturer standards, making it the ideal backup replacement for premium vehicles.
Perfect for drivers who demand:
- ✓ Uncompromising backup support to keep vital vehicle electrical components operational at all times

Frequently Asked Questions
Why do modern cars require a secondary auxiliary battery?
Modern luxury and Start-Stop vehicles carry intense electrical loads. When the engine shuts down at a red light, the auxiliary battery takes over to power onboard comfort systems, dashboard electronics, and climate features. This isolates the main starter battery, allowing it to retain full power to restart the engine instantly.
Is this battery completely maintenance-free?
Yes, this battery features a fully sealed, maintenance-free architecture. Its internal configuration drastically reduces fluid evaporation and fluid breakdown over time, meaning you will never have to access cell caps or perform manual water top-ups.
What do the flame arrestor and degassing hole do?
The EN-compliant degassing hole allows safe gas release under extreme charging conditions, while the integrated flame arrestor prevents external sparks or ignition sources from reaching the internal gases, providing maximum safety inside the vehicle chassis.
Can I use this battery as the primary starter for my car?
No. The VARTA AUX14 is designed with a 13 Ah capacity and 200 CCA output optimised exclusively for secondary backup applications and supporting electronics. It does not have the massive cold-cranking capacity required to start a typical automotive combustion engine.
