Ken Clark from Rotronics highlights the importance of regular 12V battery maintenance for both electric and internal combustion engine vehicles. AGM batteries in modern vehicles require precise charging settings to avoid premature failure, unlike older flooded lead-acid types. EVs rely on the 12V battery for initial system activation, making it essential for vehicle operation despite the lack of a starter motor. Specialist equipment is necessary for accurate testing of EV auxiliary batteries, which differ from ICE vehicle batteries in load requirements. Regular 12V battery testing can prevent vehicle downtime and generate additional revenue for workshops through battery replacement and charging services.
Why it matters for your car
Regular 12V battery maintenance prevents vehicle downtime and ensures reliable operation, crucial for drivers of both EVs and ICE vehicles.
For plug-in hybrids, AutoScan for Windows can read standard engine and emissions fault codes through a compatible ELM327 adapter; charging-system and high-voltage faults require vehicle-specific equipment.
