To determine the best car battery we looked at the following considerations: battery type, CCA rating, and reserve capacity. Most drivers will be limiting their selections to lead-acid and AGM batteries. However, the CCA rating that’s best for your vehicle will vary depending on the type of car you drive. And likewise, reserve capacity is important if you intend to power a range of electrical systems. If you’re interested in hands-free control options for your vehicle, then read our best car accessories guide.

After considering all of the above, we nominated the Optima Batteries 8020-164 35 RedTop Starting Battery as our Top Pick. In addition to having a solid 720 CCA rating, we liked that it featured a 90-minute reserve capacity. And the fact that it’s a lead-acid battery means that it’s virtually maintenance-free.

How We Decided

No one thinks about the battery in their car, SUV, or truck until there’s something wrong with their vehicle and it’s time to replace it. There are a lot of options, and unless you work in the automotive industry, it can be overwhelming. To narrow down the selections, we prioritized the following factors — battery type, CCA rating, and reserve capacity.

It’s important to note that we highlighted some of the most popular batteries that are available on the market. But it’s still your responsibility to confirm that the desired battery is compatible with your vehicle. Always refer to the sizes, ask a sales associate, or refer to the compatibility charts when shopping online.

First, we considered the battery type. Within our guide, we focused our efforts on AGM and lead-acid batteries as these are the two most popular options the average car, SUV, or truck owner will encounter. Our Top Pick and #5 selections are lead-acid batteries while the remaining options are AGM. Lead-acid is ideal if you don’t want to deal with battery maintenance.

Next, we looked at the CCA rating. While CCA ratings are important on all batteries, the range you prioritize is going to depend on the type of vehicle that you drive. While traditional cars are compatible with lower CCAs, anyone who owns an SUV, truck or performance car should prioritize higher CCAs of at least 500.

And finally, we considered the reserve capacity. It’s important to note that not all manufacturers list the reserve capacity. So, where available, we’ve provided this information to help you make an informed decision.

Car Battery Buying Guide

Most Important Things to Consider

  1. Battery Type
    Car batteries can be divided into three main categories, lead-acid, absorbed glass mat (AGM) and lithium-ion. Lithium-ion batteries are high-performance rechargeable models that are typically reserved for electric or hybrid cars. They also tend to be the priciest option. Lead-acid is one of the most common options for cars, SUVs, and trucks. Wet-cell and gel-cell batteries also fall into this category. But on the whole, lead-acid batteries are considered the most affordable options. And AGM batteries offer better performance because of their design which features an electrolyte solution that is close to the metal plates. These feature a slower discharge rate and are also considered more sustainable because the bulk of the parts can be recycled.
  2. Cold Cranking Amps (CCAs)
    CCA references how many amps a battery must emit at zero degrees for up to 30 seconds at a rate of 7.2 amps. This is an important statistic, especially if you live in a part of the country that experiences cold weather. The higher the CCA rating, the more confident you’ll be that your vehicle will be able to efficiently start in cold weather thanks to the stronger cranking power. As your vehicle ages (especially in colder climates), definitely consider the strength of the battery’s amps CCA rating, otherwise your battery may perform poorly. If you own an SUV or truck, you should look for batteries that offer a CCA of 500 or better.
  3. Reserve Capacity
    Reserve capacity represents a battery’s run time with a discharge of 2.5 amps. This is an important figure because it refers to how much power you can draw from your car’s battery to power the other systems in your vehicle such as sound systems, air conditioning, etc. In terms of reserve capacity, AGM batteries tend to offer the best performance with the potential to hold as much as 80 percent of their charge after experiencing a deep discharge.
  4. Operating Temperature
    Most of us live in parts of the world where you might experience extreme highs or lows. However, most batteries have a Goldilocks zone that ranges between 68 and 86 degrees Fahrenheit. Look for batteries that are designed for temperature extremes such as 40 degrees below and 176 degrees Fahrenheit.
  5. Size
    While many batteries are designed to work with a range of vehicles, it’s always important to confirm that a car battery will safely fit under the hood. Specifically, your battery should never touch the hood of your vehicle. Doing so could encourage fires and lead to extensive damage. As a precaution, you should always ensure that you have at least a 3.4-inch clearance between the top of the battery and the hood of your vehicle. Once your battery’s set in place, you’re ready for some driving and even some heavy towing with the best fifth wheel hitch if you tow frequently.

Car Battery FAQs

How do I know if I have a bad car battery?

The most obvious sign that your car battery might have a problem is if your vehicle won’t start. But another common sign is that some of the other electric-powered accessories on your vehicle aren’t as powerful as they once were. For example, you may find that your headlights are dimmer than usual.

Why are cranking amps so important for car batteries?

This is an important figure because it will directly impact how easily you can start your car in colder weather. While most standard cars and even SUVs will find lower CCA batteries to be more than enough to start their car, the same can’t be said for larger SUVs and trucks. Specifically, most sedans will be fine with a battery in the lower range of up to 400 CCAs. But many SUVs and trucks should prioritize CCAs between 700 and 1,000 amps. And truly heavy-duty trucks should focus on CCAs of 1,000 or more.

How many years do car batteries last?

It’s important to keep in mind that while most brands will provide a range for the life cycle of their batteries, it’s always going to depend on your real-world behaviors with your cars. Lead-acid batteries tend to last for two to three years before they need to be replaced. However, these batteries cannot be repaired and must be replaced when they no longer work. In contrast, AGM batteries can be serviced.
