The RAC has issued a crucial winter warning to drivers across the UK, urging them to switch off five specific buttons in their vehicles to prevent the dreaded flat battery scenario that plagues many motorists during the cold January months.
Essential Checklist to Prevent Battery Drain
According to the motoring organisation, drivers should make it a habit to switch everything off at the end of each journey. The five key items that need attention are:
- Lights – Ensure all interior and exterior lights are properly switched off
- Heater and fan – Turn off climate control systems completely
- Heated rear windscreen – Make sure this common battery drainer is deactivated
- Radio and entertainment systems – Power down all audio equipment
Nick Mullender, RAC mobile servicing and repairs team leader, emphasised the importance of this advice, particularly for the millions of drivers returning to their vehicles after the festive period.
Additional Precautions for Winter Driving
The RAC recommends several additional measures to ensure your vehicle starts reliably during cold weather:
- Unplug dashcams and devices – Remove any accessories that could drain the battery overnight
- Inspect battery connections – Check terminals are tight and free from corrosion
- Test older batteries – Batteries over four years old are particularly vulnerable in cold conditions
- Take proper drives – A decent run charges the battery more effectively than brief starts
Advice for All Vehicle Types
Mullender highlighted that this guidance applies to all drivers, regardless of their vehicle type. "There's no exception either when it comes to the type of car you drive," he stated. "Electric vehicles face the same risk as internal combustion engines because they also depend on 12-volt batteries for starting."
The combination of extended periods without use during holidays and recent cold weather creates what the RAC describes as "a perfect recipe for the 'flat battery blues.'" This is particularly relevant for families with multiple vehicles who may only use one car regularly, or anyone returning from holidays where their car has been left parked.
Proactive Maintenance Recommendations
To avoid unexpected battery failure, the RAC suggests:
- Taking vehicles for occasional drives before you actually need them
- Keeping electric vehicle high-voltage batteries charged above 20% during winter months
- Planning ahead if your vehicle has been unused – give it a good run even if just to fill up with fuel
- Allowing extra time to address any starting issues before essential journeys
Remember that battery acid is highly corrosive to both skin and vehicle paintwork, so handle with care during any maintenance checks. By following these simple but effective guidelines, drivers can significantly reduce their risk of battery problems during the challenging winter months.
