The combination of extreme summer heat and salt-laden coastal air takes a heavy toll on car batteries, often causing them to fail well before their expected lifespan. Mobile Mechanic Durban offers a complete on-site battery and electrical service — from a simple jump start to full alternator replacement — anywhere in the greater Durban area.
Our battery service begins with a proper load test using professional diagnostic equipment. This tells us the actual condition of your battery, not just the surface voltage. A battery can show 12.6 volts and still fail under load. We test cold cranking amps and internal resistance to give you an honest assessment of remaining battery life. If your battery is failing, we carry a range of popular replacement batteries on our service vehicle and can fit a new one on the spot in most cases.
Beyond the battery itself, we diagnose and repair the full charging and starting circuit. If your alternator is not charging properly, a new battery will go flat within days. We test alternator output, check the drive belt condition and tension, and inspect all wiring connections for corrosion — a particular problem in Durban's humid, salty environment where terminal corrosion can develop rapidly.
Starter motor problems are another common callout. Symptoms include a clicking sound when turning the key, slow cranking, or complete silence. We can test the starter motor in situ and, if replacement is needed, carry out the job at your location for most vehicle models.
Our electrical fault-finding service covers a wide range of issues: parasitic battery drains, faulty sensors, non-working lights, window motors, central locking problems, and dashboard warning lights. We use professional scan tools and wiring diagrams to trace faults methodically rather than guessing and swapping parts. Whether you are stuck at home in Morningside or at the office in Umhlanga Ridge, we come to you with full testing equipment.
Durban's climate is particularly harsh on electrical components. The humidity promotes corrosion on connectors and earth points, while the heat degrades battery chemistry faster. We recommend a battery health check every six months and proactive terminal cleaning to prevent the kind of sudden no-start that ruins your morning commute.

Battery replacement (fitted): R1,200–R2,800 | Jump start callout: R350–R600 | Alternator replacement: R2,500–R5,500 | Starter motor replacement: R1,800–R4,500. Prices depend on vehicle make and model.
All prices are estimates. We provide a firm quote after inspecting your vehicle. No hidden fees — you approve the price before we start.
Typically 2 to 4 years in Durban's coastal climate. The heat and humidity accelerate chemical degradation and terminal corrosion. We recommend testing your battery every 6 months once it passes the 2-year mark.
Yes. We offer roadside jump start services across Durban. If your battery is too far gone for a jump, we carry replacement batteries and can fit a new one on the spot for most popular vehicle models.
Warning signs include dimming headlights, a battery warning light on the dashboard, electrical accessories behaving erratically, or a whining noise from the engine bay. If your new battery keeps going flat, the alternator is the most likely culprit.
We provide battery & electrical services across these Durban suburbs and surrounding areas.
