What your alternator and battery do

Your battery starts the vehicle and powers electrical systems when the engine is off. Once running, the alternator generates electricity to recharge the battery and supply power to lights, heating, infotainment and engine management systems.

If either component begins to fail, it places extra strain on the other — often leading to flat batteries, warning lights and electrical faults. Early diagnosis helps avoid being stranded and prevents further damage.

Common warning signs

You may need an alternator or battery check if you notice:

• Battery or charging warning light on the dashboard
  
  

• Dimming or flickering headlights or interior lights
  
  

• Slow or difficult engine starting
  
  

• Battery repeatedly going flat
  
  

• Whining, grinding or unusual noises from the engine bay
  
  

If you’re experiencing any of these issues, we recommend booking a charging system inspection as soon as possible.

Frequently asked questions (FAQ)

Q: Can an alternator be repaired instead of replaced?
A: Some faults can be repaired, but if internal components are worn or damaged, replacement is usually the most reliable long-term option.

Q: How long does alternator or battery replacement take?
A: Most jobs are completed within a few hours, depending on vehicle make and access.

Q: Do you test the battery and alternator together?
A: Yes — a failing alternator can drain a good battery, so we always test both.

Q: Will you check the rest of the electrical system?
A: Yes — we inspect belts, wiring and connections as part of the diagnosis.
