How do I know whether it is the battery or alternator?

A battery test checks stored capacity and starting performance; a charging test checks alternator output and ripple. Symptoms overlap, so voltage alone is not always enough.

Does a stop-start car need a special battery?

Usually yes. EFB or AGM batteries are specified according to the vehicle’s energy-management system, and some cars require battery registration after replacement.

Will a jump start fix a flat battery?

It may get the car running, but it does not explain why the battery discharged or confirm it will restart. Testing and charging may still be needed.

Can SSK Mechanics do this at my home or workplace?

Many electrical, battery & lights jobs are mobile. Services needing a vehicle lift, controlled workshop equipment or high-voltage isolation are marked as workshop jobs; where available, SSK arranges collection and return.

What if I choose the wrong service?

If you cannot confidently match the symptom to a job, choose Find The Fault instead. The technician investigates the cause and explains the correct repair before parts are ordered, helping you avoid paying for a guessed part.

Petrol & diesel vehicles

Conventional vehicles use a 12V electrical system powered by the alternator when the engine is running and the battery when stationary.

Hybrid & electric vehicles

Electric vehicles have both a high-voltage system (300-800V for the drivetrain) and a conventional 12V system for accessories. Only qualified EV technicians should work on the high-voltage system.
