Winter can be a wonderland; playing in the snow, making snowmen, and having snow fights. It can be such a dream. The extreme cold, on the other hand, is another story. Short days, miserable weather and if you don’t have the best car battery for cold weather then you can find yourself stranded in the absolute worst time. To prevent this, you should buy a car battery that can operate despite the tough climate. Thankfully, this article has vetted the market for the popular car options for low temperatures. We also explain the useful metrics to decide on the right option for your car and give some advice on how to keep it alive at low temperature. Read on to find out more.
What is CCA?
Cold Cranking Amps (CCA) is a standard across the motor industry to establish a battery’s ability to start an engine in the freezing cold. It is the current that a 12-volt battery can deliver for 30 seconds at -18°C (0°F) as it maintains a terminal voltage of at least 1.20 volts per cell. CCAs show how well a battery will perform in the icy winter. As a battery ages, its starting power depreciates and so choosing a battery with higher starting power should assure you of its long use. Be wary though, too many CCAs in warm climates is not a good idea and will adversely affect the battery’s performance.

How to keep your car battery charged in the cold weather?
Imagine for a second, it’s a severe winter and you’re in a hurry. You urgently want to get to somewhere nice and warm, so you jump into your car, turn the key and then nothing. You do it again, but it won’t start. You pop the hood open and check only to find your battery is dead. You would want to prevent this by all means and here are some useful tips to keep your battery fully charged throughout the winter.
- Before the cold starts, check your battery
- Get a battery charger
- Be conscious of accessories
- Keep it clean
- Take care of your engine and opt for appropriate oil
It’s a good idea to schedule an auto care check-up prior to the blistering cold to know the status of your vehicle. When you know what your battery’s charge is then you can act more efficiently and choose the right interventions to prolong its charge.
A quality battery charger, sometimes called battery tenders, is a more affordable option than purchasing a new winter car battery every year. You should buy a battery charger with a float, storage, or maintenance charge mode otherwise it will be a waste of money.
Even if you bought the best car battery for cold weather, if you leave all your accessories on before turning off the vehicle, your battery won’t last that long. Make sure your AC, lights, and radio are off before you park. And when you start the car up again, wait a little bit to let your alternator charge the battery before turning all these loads on.
When the temperatures drop, the electrical resistance increases and the engine oil gets thicker. This already makes the battery work harder without dirt and debris on the battery terminals, that further increase the resistance. Any white powder around the battery terminals is corrosion that can be easily addressed with a damp cloth, a toothbrush, baking soda, and H20. Afterward, apply dielectric grease to prevent more corrosion from happening.
While low winter temperatures may affect motor oil to a large extent by making it thicker, it is crucial for caring drivers to avoid this negative phenomenon by adding winter oil. Very thick oil is the culprit for engine working slower and the battery spending more charge on every application. There are different types of winter oil that can withstand different milestones of temperatures below zero, so it is up to you to decide what one to choose based on how low the temperature can get in your country.
How many cold cranking amps a battery have?
So now that you’ve decided on a battery you may be wondering to yourself, how many cold cranking amps should a battery have? Well, there are various factors that need to be taken into consideration to determine the right CCA to start an engine. Engine size, car make, auxiliary loads, just to name a few. The car manufacturer has taken all the necessary considerations so it is best to purchase a battery with at least the same CCA rating as the vehicle’s original battery. A lower CCA rating could result in unnecessary problems.
Where and how to store battery in winter?
Experienced drivers know that extreme winter temperatures can affect even the best batteries for cold weather by reducing their capacity. Therefore, it could be very beneficial to share some impactful tips explaining how to properly maintain a car battery in winter whether it is at a full charge or not.
Here are seven effective tips that every driver should follow:
- Correct storage location. The battery may remain in the car even for long periods if the garage has adequate storage facilities. The correct temperature is important in choosing where to store it. Vehicle batteries prefer to be stored in cool and dry conditions. The optimal storage temperature for a car battery is 59° F. Storage in the basement is basically possible, but the area should be dry. It would be better to store in a house where even in winter the atmosphere is dry and the temperature stays the same.
- Make regular tests. Although this piece of advice may seem a bit trivial, you still need to be well prepared for the winter period and check the entire vehicle. However, testing the battery is the most meaningful way to make sure that everything is alright with its essential elements and total capacity. The easiest method to check the car is to utilize a computerized battery tester.
- Try to keep your high CCA battery warm when you’re not using your car. You can either leave your car in the garage or at least use a weather-proof car cover in order to prevent the vehicle from getting too cold. If you cannot afford these two methods, then try to park your vehicle in a safe place that is protected from strong wind.
- Do not be lazy and dedicate some time to clean up the battery’s terminals now and then to get rid of dirt and corrosion. You can just take a worn-out toothbrush and baking soda mixture to do this in an easy and quick way.
- Charge your battery. Don’t leave the car battery fully discharged. It’s easy to forget about it in winter. So remind yourself to check the battery state on a regular basis and recharge it.
- Try starting your battery with small pauses from time to time. If you cannot start your car during a cold winter morning, but you know that it must have some charge to share, then you should wait for a while and try again. In case the battery does not seem working again at all, check the battery connections for corrosion or dirt. This should be helpful too, as it’s your only chance to start the car normally without charging the best car battery for cold winters again.
- Stay patient after starting the engine. It is vital to let the alternator charge the car battery properly before you can turn on the radio, lights, etc. This will help you prevent the situation when the battery gets dead very quickly at the most inconvenient moment.
