Cold Weather Car Battery Care

There are several reasons why a car battery would normally die during winter or cold weather conditions. In order to successfully protect the car battery, a little understanding of what exactly happens is important. Below is a shortlist of some of these reasons.

Reasons Behind Nonfunctional Car Batteries In The Winter

1. Reduced battery capacity

Over time, a battery loses its capacity to hold a charge even after a recharge. Cold conditions interfere with primary processes within a battery that facilitates its functionality.

This means that the battery may feel a bit more sluggish as compared to when the weather is a bit more warmer.

The fact that the battery may not be able to hold a charge like it did before only worsens its overall performance. You may have to jump-start your battery more often than you may want to when winter finally comes knocking.

2. Increased power draw

When its cold, the car’s electrical system has to work a bit harder to feed the starter motors. In some cases, especially where the battery is over three years old, this may cause its death. In other words, the battery may not be fully up to that particular task.

Power drawn by accessories such as lights, wipers, and the heater also works up a battery in these conditions. Unfortunately, one may not always be in a position to control the use of accessories in a car since most of them are more or less unavoidable when driving.

Maintenance Tips For Your Battery During Winter

1. Test its capacity

Most automobile repair shops have the equipment to measure your battery’s charge holding capacity. The capacity is measured in Cold Cranking Amps aka CCA.

By knowing the level of your battery’s CCA, you become aware of the level of functionality your battery would give off during cold weather conditions.

2. Keep your car enclosed

Parking an automobile in an enclosed space, for instance, a garage has proved rather helpful when trying to dodge battery breakdowns in cold weather.

If possible, keep the garage heated all night through. This way, the car remains warm ultimately evading any cold-related complications.

3. Switch off all loads

When the car is not in use, especially at night, it is advisable to turn off all power loads. By doing this, you avoid possible power drain to your battery.

4. Your battery needs cleaning too

The battery runs through chemical processes; this explains why corrosion is a rampant related condition. Even if in full capacity, corrosion is a threat to any battery life.

Cleaning the battery every once in a while is an effective way to ensure the battery works at full capacity no matter the weather.

When Is It Time To Replace Your Battery?

Sadly, no matter the amount of effort you put into keeping your battery in top-notch condition, a time comes when the need to replace it becomes undeniable. This is because even the best of batteries eventually wear out.

The good thing is that you can easily notice when it’s about time, thanks to the few signals the battery manifests. Below are a few of such indicators that will help you know its time to replace your car battery.

1. When the engine cranks with no result

This probably the most common of all red lights. It is never a good sign when you turn the key and all you get is an engine crank.

A crank with no actually start is a perfect indicator that the battery is tiring up. Although this may not always be the case, a few such experiences should be enough to get you on your feet and looking for a battery replacement.

2. Sluggish engine crank

In other cases, the car will start with a crank. It, however, may take quite a while to do so. Slow engine crank is another indicator you cannot afford to ignore.

An immediate test is essential once you notice such symptoms to avoid any later inconveniences.

3. An unbearable odor from the battery

This is usually due to battery leakages and often smells like rotten eggs( typically the smell of sulfur). These leaks corrode the battery deteriorating its condition and performance.

You can clean the battery to counter this. Even so, if it persists, it is definitely an indicator that it is about time to get a new one.

4. Age

The older your battery grows, the higher its chances of burning out. Typically, batteries last for three to five years, depending on the conditions of their environment.

Once your battery hits the three-year mark, you should keep tabs on its functionality. That goes without saying.

5. The bloated appearance of the battery case

Even with no prior knowledge, a swelling battery is definitely a cause for alarm. This is usually as a result of constant overheating. A battery test would be in order once you notice this signal.

Now that you understand why your battery may act up during winter, let’s get down to the core subject of this article.

Battery manufacturers recognize that cold weather conditions are not the friendliest to your car battery. The market offers a good number of batteries that are a better option in such conditions.

The following are short reviews of such batteries. This article goes a step further by indicating the best overall option, the cheapest and such.

Conclusion

Based on the above reviews, adverse weather conditions don’t always mean struggling to start your car. With the right battery, you can go about your everyday activities without a single worry.

Although each of these batteries has something special to offer, they all share the ability to keep functioning even in subzero conditions.

Depending on your taste and preference, any one of the above batteries should relieve you of any pressure that might have been brought about by your old battery during cold weather seasons.
