Unless you are using an electrically operated car, keeping your car battery in the best situation possible is crucial. Batteries can function on their own but there are instances where the functionality and reliability of a battery are cut short hence your plan with the car is cut short too.
Ideally, car batteries can last up to 3-4 years but they can also last less because of alternator faults, a prolonged period of discharge, extreme temperatures and many more. Among all of these, extreme cold weather does the most damage. This article will take you through what to look out for when buying your next car battery, the best car battery brand for cold weather and how to fix your car battery. So to say, you are getting prepared for this winter!
You should not go about changing your battery if you are not sure that it is damaged. Signs that your battery might need a replacement include difficulty starting the car, dim interior and exterior lights and perhaps when your car has been sitting for a long time.
Why exactly are car batteries at risk during extreme cold weather?
Well, the answer is not far-fetched. Car batteries use liquid or molten electrolytes which get affected during cold weather. Below a certain temperature, car batteries start draining. Sometimes, the drain leads to a permanent loss of the battery.
How to know the best car batteries for cold weather
Best car batteries for cold weather have these features; perfect size and spec, cold cranking power, reserve capacity, warranty and new production date.
Battery size and Spec
This refers to the size and terminal position that fits your vehicle. You can check this through the Battery Council International, BCI number which is usually pasted on the battery. Knowing the perfect size and spec ensures that the battery fits the battery tray of the car and it touches the battery cable.
If you are not sure which battery size to choose, check the one inscribed on your current battery.
Cold Cranking Amps
The best car battery for extreme cold weather has high cold cranking amps. CCA is a measure of how a battery will perform during cold weather when it is at its weakest.
It is important to note that high-cranking power doesn’t always mean the battery is the best, it just indicates the amount of energy that it will use in extreme weather conditions.
Reserve capacity refers to how long a car battery can deliver a certain ampere of current at normal temperature and voltage.
It is measured in minutes. Car batteries with 140 reserve capacity and above are suitable for most cars.
Most car battery brands offer a warranty when you shop for your battery directly from them. The warranty ensures that you get the maximum use of a car battery because you can get a replacement or a refund if it does not perform until the given time.
However, to be eligible for a change or refund, be sure that the battery had not suffered abuse or damage by you.
Unfortunately, car batteries start to deteriorate from the moment you purchase them. Hence, it is important to buy batteries with a production date not too far from the purchase date.
A car battery with a purchase date of six months and below is perfect for your car.

Also, AGM batteries are resistant to vibrations.
The Optima brand produces three batteries; Red top, Blue top and Yellow top. Optima batteries operate with a spiral cell technology that delivers high starting power in a short period.
Red Top optima batteries are made with AGM batteries, so it is suitable for cold weather. Yellow Optima batteries are known for their reserve capacity while the blue top is renowned for its deep cycle battery with high CCA. The 3-year warranty on optima batteries is also an added advantage.
Odyssey is a great brand for a reliable, lasting and quality car battery. With over 100 years of experience in manufacturing, they have developed the Extreme series, Performance series and Pro series.
These batteries are outstanding because of their extended service life, vibration resistance and extreme temperature resistance.
The Extreme Series has incredible deep cycling capabilities and rapid recovery,
Odyssey Pro Series charges faster than traditional batteries and the Performance Series has a high reserve capacity.
Absorbed Glass Mat technology is also used in the DieHard battery. DieHard batteries are renowned for their patented “Stamped Grid technology,” which makes them incredibly robust, upkeep-free, and resistant to vibrations. In conclusion, the DieHard Platinum is an excellent option for a car battery in cold climates.
The interstate brand produces the best car batteries for varying weather. Some of their series function more in places with hot temperatures and some perform optimally in cold regions.
