Motorists across the UK are being advised to meticulously check their vehicles before leaving them parked, as the ongoing cold snap threatens a surge in battery failures. The simple act of ensuring all electrical systems are off could be the difference between a smooth start and a frustrating breakdown.
Why Cold Weather is a Battery's Worst Enemy
The core of the problem lies in the chemistry of most car batteries. The majority rely on a liquid electrolyte solution to hold their charge, and this solution's performance is directly impacted by temperature. While it requires extremely severe frost for the fluid to freeze, even typical British winter cold can significantly reduce the solution's ability to transfer full power to the starter motor.
This diminished capacity is the primary reason vehicles become reluctant to start on chilly mornings. The battery simply cannot deliver the same 'punch' as it can in warmer conditions, leaving drivers stranded.
Proactive Steps to Prevent a Flat Battery
Leading automotive service provider Kwik Fit has issued clear guidance to help drivers avoid this common winter headache. They emphasise that "flat batteries always seem to happen at the worst possible times." While a jump-start from another vehicle using cables is a traditional solution, it relies on having a helpful motorist and the right equipment to hand.
To prevent finding yourself in this situation, a thorough pre-parking check is crucial. Kwik Fit advises: "When parking, double-check that you have switched off anything that might drain your battery when stationary." This includes:
- Windscreen wipers
- All lights (interior and boot)
- The radio or infotainment system
- The heater and fan blower
As an added efficiency tip, they recommend avoiding unnecessary use of the heater while driving, as it also increases fuel consumption.
Investing in a Backup Solution
For added peace of mind, motorists may want to consider carrying a portable power solution. "In case the worst should happen... you may want to consider investing in a car battery booster," Kwik Fit suggests. These compact, rechargeable devices can be clipped directly onto a flat battery to provide enough charge for a start, eliminating the need for jump leads and another car. Retailers like Halfords stock such jump starter powerbanks, with prices starting from around £61.
Long-Term Battery Health in Winter
Perrys, another automotive authority, underscores the critical role of the battery. "A car battery is one of the most important parts of the car. Without it, the car engine won't start," they state. They warn that a weak battery can even cause damage to internal engine components, making proactive maintenance a money-saving exercise.
They explain the seasonal strain: "During winter, batteries experience greater stress than usual, as the chemical mechanism inside the battery that generates and stores electricity, is impacted by cold temperatures, which causes it to deplete more quickly than usual."
To reduce strain during ignition, they recommend a simple manual driving technique: "The starter motor and battery are relieved of stress when you press the clutch pedal while starting the car." Furthermore, leaving a manual car in gear when parked serves a dual purpose: it acts as a reminder to depress the clutch when starting and helps prevent the vehicle from rolling away.
By combining these preventative checks, considering backup power, and adopting careful starting habits, drivers can significantly improve their chances of a trouble-free winter on the roads.
