A lot of cars in Al Quoz 3 are waiting: for bodywork, for a part, for an insurance approval. A car that stands in a workshop yard for a month with doors opened and closed every day ends up with a flat battery, and the garage often only finds out when it is time to move it.
A mobile technician suits this better than sending a driver out for a battery. We test what is fitted first. A battery that was sound when the car came in usually recovers with a jump start and a proper drive. One that was already old will need replacing before the car is handed back.
