Auxiliary Car Battery Replacement in Dubai – Fast 24/7 Service

An auxiliary battery is a smaller, secondary battery found in many modern premium vehicles—particularly Mercedes-Benz, BMW, Audi, and newer Volkswagen models. Think of it as a backup power source that handles all your car's electronics while the main battery focuses solely on starting the engine. Most new car auxiliary battery installation happens at the factory on higher-end models equipped with start-stop technology and advanced driver assistance systems, though some aftermarket dual-battery systems can be added to vehicles that didn't come with one originally.

Most auxiliary batteries last between 3-5 years, but in Dubai's extreme heat, you're more likely looking at the lower end of that range—sometimes even less. Heat is the number one killer of all car batteries, and since the auxiliary battery is typically smaller and works harder than your main battery, it often degrades faster. Many drivers ignore the early warning signs until they're facing complete electrical failures, which is why auxiliary battery malfunction repair shops in Dubai stay busy year-round replacing batteries that died prematurely from heat exposure and neglect.

Technically yes, but it's not as simple as swapping out a regular car battery. If you replace auxiliary battery yourself without the proper diagnostic equipment, you'll end up driving around with permanent warning lights and a malfunctioning start-stop system. The physical installation is straightforward—usually just a few bolts and connectors—but modern vehicles like Mercedes, BMW, and Audi require the new battery to be coded and registered in the car's computer system.

The cost of an auxiliary battery replacement depends on your car’s make, model, and battery type. At iTyreCare, prices typically range between AED 700 and AED 1,500.
