Winter & Batteries

Sep 10, 2018


As the temperatures drop and snow starts to fall, ensuring your car's battery is in top condition becomes crucial. Winter can be particularly harsh on batteries, often leading to unexpected breakdowns or difficulties starting your vehicle. At The Auto Experts, we understand the importance of a reliable, high-performance battery, especially in the colder months.

The Impact of Winter on Car Batteries

Extreme cold weather negatively affects the functionality of car batteries due to various reasons. Firstly, lower temperatures increase the thickness of engine oil, resulting in more effort required to turn over the engine. This increased strain on the battery can drain its charge quickly and may prevent the car from starting altogether.

Furthermore, vehicle components, such as heaters and defrosters, are often used more frequently during winter. These additional power demands can put a strain on the electrical system, including the battery, potentially causing it to weaken over time.

Proper Battery Maintenance

To ensure optimal performance, it's important to undertake regular battery maintenance, especially before the arrival of winter. Here are some essential tips to maintain your car battery:

1. Check Battery Age

Start by checking the age of your battery. Most automotive batteries have a lifespan of 3-5 years, so if your battery is approaching this age or older, it's a good idea to have it professionally tested and consider a replacement if necessary.

2. Clean Battery Terminals

Over time, corrosion can build up on the battery terminals, affecting the connection and the flow of electricity. Regularly clean the terminals using a mixture of baking soda and water to remove any built-up residue, ensuring a strong and efficient electrical contact.

3. Keep the Battery Charged

During periods of inactivity or infrequent car usage, use a battery maintainer or trickle charger to keep the battery charged. This prevents the battery from losing charge and extends its overall lifespan.

4. Insulate Battery from Extreme Cold

Protecting the battery from the harsh winter conditions can help maintain its performance. Consider using an insulation blanket or battery wrap designed for cold weather to keep the battery warmer, reducing the strain on it during extremely low temperatures.

Choosing the Right Battery for Winter

When it comes to selecting a battery suitable for winter, quality and reliability are paramount. Here are some key factors to consider:

1. Cold Cranking Amps (CCA)

Cold Cranking Amps (CCA) is a critical specification to consider when choosing a winter battery. This rating indicates the battery's ability to provide a high amount of power even in extremely cold temperatures. Opt for a battery with a higher CCA rating to ensure a quick and reliable start, even in freezing conditions.

2. Reserve Capacity (RC)

Reserve Capacity (RC) denotes how long a battery can continuously supply power in case the alternator fails. A higher RC ensures that even under challenging weather conditions, your vehicle will have sufficient power to function optimally for an extended period.

3. Trusted Brands

The market offers various battery brands, but it's crucial to choose from reliable and reputable manufacturers. Opt for batteries from trusted brands known for their durability, performance, and ability to withstand extreme temperatures.


Preparing your car's battery for the winter season is essential to avoid potential problems and ensure a smooth start every time you turn the key. By following proper maintenance procedures and selecting a battery designed for winter conditions, you can have peace of mind knowing that your vehicle is reliable, regardless of the temperature outside.
