Before we dive into the details of the best cold weather car batteries, let's first address a few important questions (we also have another list of FAQs down below).

What Type of Battery is Best for Cold Weather?

An Absorbed Glass Mat (AGM) battery is better in cold weather than a standard flooded battery (or what we might classify as a “normal” car battery). Although AGM batteries are often more expensive, on average they produce more cranking power, higher cold cranking amps, lower discharge rates and are simply more durable. As a result, AGM batteries tend to make a good winter battery.

AGM batteries use an absorbent glass mesh (hence the name) to harness energy. Unlike traditional flooded batteries, AGM batteries have a special fiberglass mat to absorb the electrolyte solution. This design allows AGM batteries to store electrolytes in a "dry" state rather than in liquid form. You'll often hear the term "spill-proof" or "maintenance-free" in reference to AGM batteries, which means acid won't leak if tilted. This is because the glass mat absorbs the sulfuric acid in the battery.

Because the electrolytes are absorbed in a tight fiberglass mat instead of suspended lead plates in the electrolyte solution, AGM batteries are more resistant to vibration than traditional batteries, which can reduce their lifespan. . This same design also allows them to increase your car's starting power in cold weather.

#1: Best Overall: Optima REDTOP

The Optima REDTOP wins our pick for best overall car battery for cold weather, in part because of their long history. Optima batteries have been one of the most reliable and dependable batteries on the market for 40 years. The REDTOP is specially designed for adverse conditions, using a technique called "Spiral Cell Technology" which provides more cranking power in a shorter amount of time.

Optima's Spiral Cell Technology is a series of individual cells wound in a spiral composed of two plates of pure lead (99.99%) coated with lead oxide. Each of these spiral cells ends up looking like a jelly roll when finished. Benefits include a splash-proof and maintenance-free design, greater vibration resistance and faster recharging.

Optima REDTOP batteries are of AGM design, which means that they offer all the advantages described above.

Warranty: 3 years free replacement.

Where to buy: The Optima REDTOP battery is available at Advance Auto Parts for around $200.

#2: Top Runner Up: DieHard Platinum

DieHard is a familiar and trusted name among car batteries on the market. If you've ever been a Sears Auto Center customer, they probably installed a DieHard battery in your car. If you followed racing back in the day, you might remember Richard Petty and Bobby Allison using DieHard batteries in the early 70s.

The DieHard Platinum battery offers the benefits of Absorbed Glass Mat technology (described above), which means it can handle today's automatic start-stop systems. DieHard batteries are also known for their patented Stamped Grid technology, which makes them more durable, maintenance-free, and resistant to corrosion and vibration. In short, the DieHard Platinum is a good choice when it comes to choosing a cold weather car battery.

Warranty: 3 years free replacement.

Where to buy: The DieHard Platinum battery is available at Advance Auto Parts for around $220.

Fun fact: the average DieHard battery sold for $23.45 in 1968.

We also recommend getting this portable NOCO jump starter. kit from Amazon. When fully charged, it can provide up to 20 individual starts. You can use it to help your friends and family who didn't replace their car battery before winter!

#3: Best deep cycle: Optima YELLOWTOP

The Optima YELLOWTOP battery is 15 times more vibration resistant, making it an ideal choice for something like a Jeep or a highly customized work truck.

The YELLOWTOP from Optima Batteries is the best choice if you have equipment on your vehicle that requires extra power to run. For example, if you drive a heavy-duty vehicle, such as a work truck or service van, or if you have a 4x4 vehicle equipped with accessories like off-road lights and winches. In this case, you'll need something with more power than the average car battery.

To that end, the Optima YELLOWTOP is known for its reserve capacity and deep cycle use. Deep cycle capability means a higher sustained energy level for a longer period of time. This also makes the YELLOWTOP an ideal dual-purpose battery, meaning it can accommodate tractors, forklifts and other industrial vehicles. Like the other entries on this list, the Optima YELLOWTOP also benefits from an absorbed glass mat design.

Warranty: 3 years free replacement.

Where to buy: The Optima YELLOWTOP battery is available at Advance Auto Parts for around $250.

#4: ACDelco Professional AGM Battery

ACDelco is owned by General Motors, but you don't have to drive a GM vehicle to benefit from ACDelco's proven history. ACDelco offers two battery lines, Professional and Advantage, that will fit almost any make or model. According to ACDelco, its batteries meet or exceed the power requirements of 98 percent of all vehicles on the road.

Like the other batteries on this list, ACDelco offers all the benefits of an AGM design but offers some features unique to their brand. For example, ACDelco uses a sealed pressure valve system, which prevents acid damage to the terminals and increases battery life.

Warranty: 3 years free replacement.

Where to buy: You can buy the ACDelco AGM Professional battery for around $220.

#5: DieHard Gold Battery

The DieHard Gold battery is cheaper than the Platinum variant we described above. However, the DieHard Gold is by no means a "cheap" battery. The DieHard Gold features the same stamped grid technology as the Platinum, which means it will provide plenty of starting power through the winter. Additionally, DieHard claims to have improved the battery design to the point that it now offers an increase in electrical flow of over 60%.

If your vehicle doesn't have a high number of connectivity features, or if you don't have additional accessories that require additional power, then you won't need the more expensive DieHard Platinum battery. You can save money because the Gold version will work just fine.

Warranty: 3 years free replacement.

Where to buy: The DieHard Gold battery is available at Advance Auto Parts for around $170.

If possible, the best time to replace your battery is before winter sets in.

Why AGM batteries are ideal for cold weather

Many vehicles today are equipped with start-stop systems that shut down the engine to prevent excessive idling. If your car is equipped with one of these systems, having a high quality battery for winter driving is all the more important. Whenever the engine shuts down, such as at a traffic light or waiting for a train, your battery takes on the responsibility of keeping everything running inside your car. While an automatic stop-start system saves fuel, it makes your battery work harder once the engine is off.

On any given trip in the average city, your vehicle may restart more than a dozen times or more, especially in a congested area or with a multitude of traffic lights. When you hold the brakes for an extended period, the engine shuts down and the battery takes over. This "transition" allows all electronic components, including your heater or navigation system, to continue to function.

By design, AGM batteries are a better option for engines with an automatic start/stop system. AGM batteries discharge energy more efficiently when the engine is off but recharge faster (via the alternator) than traditional car batteries when the engine is restarted.

If your car is left outside during the winter, it is all the more reason to invest in a high quality battery. We've put together this list of the best cold weather car batteries to help you make the right choice.

Other useful tips

Buy now: Be sure to replace your battery as soon as possible, especially if you can't remember the last time you had it changed. This will help keep your car and engine running when the weather conditions deteriorate. The links above for each car battery will take you directly to where you can purchase it.

Buy the right "group size" battery: Group size requirements vary by car manufacturer, but the best way to see what your vehicle requires is to check your owner's manual.

Don't forget the warranty: As you would with any other auto part, be sure to read the terms and conditions of the warranty when purchasing a new battery.

Ask a trusted mechanic for advice: Qualified auto technicians have the training, certifications, and experience to help you choose the right battery for your car.

Frequently Asked Questions

How cold is too cold for a car battery?

Your battery won't literally freeze unless it's incredibly cold. Yet, according to AAA, the average car battery can lose up to 60 percent of its available cranking power when the temperature drops to 0°F or lower. Since winter can impact battery life and even cause battery failure, that's all the more reason to seriously consider replacing yours with one of the recommendations on this list.

What is reserve battery capacity?

This is the time a battery will last with the headlights on, under a draw (or load) of 25 amps, until it is completely discharged. Having a battery with a high reserve capacity is a bonus, especially if you drive a vehicle with auto start/stop or with additional accessories that require extra power.

What Are Cold Crank Amps?

Like reserve capacity, cold cranking amperage (CCA) is another important term you'll see when shopping for a battery. In a nutshell, it's the number of amps that can be drawn from a 12-volt battery at 0°F for 30 seconds, while maintaining a voltage of at least 7.2 volts (or 1. 2 volts per cell). The higher the number of cold cranking amps, the higher the "cranking power" of the battery.

Although cold cranking amplifiers are essential, they are not "all purpose". With the increase in the number of electronic devices in today's cars, spare capacity is just as important. Although a battery with a high CCA rating has its advantages, your vehicle may not need such a battery. When choosing a battery, it is more important to choose the battery that best meets the requirements and specifications of your vehicle, not just a battery with a high CCA rating.
