Frequently Asked Questions
Common signs include slow or laboured engine cranking when starting, the battery warning light appearing on your dashboard, dim headlights, electrical accessories behaving erratically or the vehicle failing to start at all. We can test your battery's health quickly and advise whether a replacement is needed.
The alternator charges your vehicle's battery while the engine is running and powers the electrical systems. A failing alternator can cause a flat battery, flickering lights, electrical faults and eventually a non-starting vehicle. Signs of alternator problems include a battery warning light, dimming lights or unusual noises from the engine bay.
Yes, though intermittent faults can be more complex to diagnose. We use professional diagnostic equipment and live electrical data monitoring to identify faults that may only occur under specific conditions. In some cases this requires extended testing time to replicate the fault.
Many modern vehicles, particularly European brands such as BMW, Mercedes-Benz and Volkswagen Group vehicles, require the new battery to be registered with the vehicle's battery management system (BMS) after fitting. Without registration, the system may continue to charge the battery incorrectly and shorten its life. We carry out battery registration coding as standard.
