Why AGM and EFB batteries are ideal for winter driving

As temperatures plummet, your vehicle's battery becomes the unsung hero that keeps everything running smoothly.

Frosty roads, freezing temperatures and unpredictable weather conditions all put our vehicles and their batteries to the ultimate test.

As winter sets in, the harshness of cold weather can expose the vulnerability of weak batteries, making it the prime season for battery replacements. Winter driving demands a reliable and robust power source to avoid battery failure.

Designed to withstand the strain of the colder months, AGM (Absorbent Glass Mat) and EFB (Enhanced Flooded Battery) batteries deliver reliable starting power and enhanced performance when you need it most.

1. Cold weather performance

AGM and EFB batteries excel in low temperatures, delivering optimal starting power and withstanding demanding conditions. Their advanced design ensures quick and efficient energy delivery even as temperatures drop, making them ideal for those frosty mornings and winter adventures on the road.

2. Cold Cranking Amps (CCA)

When it comes to winter driving, a battery's Cold Cranking Amps (CCA) is a crucial factor, as cooler temperatures can make ignition more difficult.

CCA is a rating that measures how well a battery cranks in cold temperatures. The CCA rating on a battery's label is tested at -17.8°C to show the energy performance in cold climates.

AGM and EFB batteries generally have improved CCA performance for reliable starting power, even in winter conditions. This is because of their robust internal designs, as they’re built to endure repeated cycles of discharging and recharging.

3. Resist deterioration from vibration

Winter roads can be unpredictable, with bumps, potholes and rough surfaces adding to the vibrations experienced by a vehicle. In challenging conditions, vibrations can pose a risk to battery performance.

AGM and EFB batteries are typically designed to resist deterioration from vibration, which helps to avoid internal damage that could compromise their longevity and reliability.

4. Faster recharge even in cold weather

Cold temperatures can reduce the overall battery capacity and slow down the charging process.

However, AGM and EFB batteries have advanced designs that enable faster recharging rates, ensuring the battery can replenish its power more efficiently. This feature is particularly important during winter when demand on the battery is higher due to the use of accessories like defrosters, heated seats and lights.

The faster recharge capability of AGM and EFB batteries helps maintain optimal performance and ensures reliable power for starting the vehicle, even in cold winter conditions.

5. Enhanced Durability

AGM and EFB batteries are built with robust materials and design elements that improve their durability and resilience to harsh conditions. They are engineered to withstand the challenges posed by cold temperatures, including temperature fluctuations and the increased electrical load during winter driving.

6. Peace of mind

Enjoy the peace of mind that comes with a durable AGM or EFB battery that you can rely on as temperatures drop.

Whether you’re driving just down the road or heading on a road trip, a robust and reliable car battery supports your winter driving requirements so you can avoid getting stranded in the cold.
