JLT is one of the few parts of Dubai where a resident can go a week without driving. That is pleasant for the driver and bad for the battery. Alarm, tracker and keyless modules keep drawing current, and a battery that is never topped up by a long drive drifts down towards 12.0V and stops cranking.
If the car is used that little, a jump start service followed by a long drive is sometimes enough. If the battery is past 2 to 3 years, it usually is not. The technician tests it in your bay and tells you which case you are in before anything is sold.
