The Exide Auxiliary battery range has been specifically developed to meet the demands of modern vehicles that rely on multiple energy sources. As vehicles become more sophisticated, the need for a secondary power supply—independent from the main starter battery—has grown rapidly. Exide Auxiliary batteries are designed to provide stable and efficient support to a wide array of electrical systems, particularly in cars equipped with Start-Stop technology, energy recovery systems, and increasingly complex onboard electronics.
These batteries are commonly found in hybrid systems where the main battery is dedicated to starting the engine or powering high-draw components, while the auxiliary battery maintains operation of vital features such as central locking, interior lighting, infotainment systems, navigation, and emergency call functions. Even when the engine is off—as it frequently is in vehicles with Start-Stop systems—the auxiliary battery continues to ensure uninterrupted power to these critical systems.
Exide Auxiliary batteries use AGM (Absorbent Glass Mat) technology, a proven solution known for its high performance, durability, and resistance to vibration and extreme temperatures. The AGM design enables the battery to withstand deep discharge cycles and frequent charge-discharge events without compromising performance or lifespan. This makes it ideal for auxiliary applications where consistent reliability is essential.
With a compact and sealed maintenance-free design, Exide Auxiliary batteries are easy to install, even in tight or concealed spaces within the vehicle. Their leak-proof construction ensures safety during operation and transport, while the robust internal structure guarantees long-lasting performance under demanding conditions.
Exide has decades of experience supplying original equipment (OE) batteries to many of the world’s leading car manufacturers. This ensures that every auxiliary battery is built to meet or exceed OE specifications, offering seamless compatibility with various vehicle makes and models. Whether you’re replacing an existing auxiliary battery or installing a new one, you can trust Exide’s engineering and quality control to deliver superior results.
The Exide Auxiliary battery line is available in several capacities and configurations to suit different vehicle types and auxiliary system requirements. Each model in the range is optimized for high efficiency, reduced internal resistance, and maximum longevity.
In today’s world of ever-evolving automotive technology, a reliable auxiliary battery is no longer a luxury—it’s a necessity. By choosing Exide Auxiliary, drivers and technicians can ensure consistent power to essential systems, greater convenience, and peace of mind on every journey.
