Benefits of Owning the Best Car Battery


There are several benefits to owning the best car battery that you can afford. Here are a few of them.

Cost Effectiveness – The best car batteries will vary in price. The most important thing to remember about price is that the price you pay should be stretched out over time. For example, if a battery costs $300 and lasts five years it costs $60 per year. While there are some great lower priced car batteries, a lot of the truly inexpensive ones will need to be replaced on a more frequently (sometimes yearly) schedule. So, if you have the money, it’s worth it to spend it on a car battery that you won’t have to replace every couple of years.

Cost Protection – All auto batteries come with some sort of warranty included with your purchase. However, not all warranties are created the same. Some are limited and some cover even the smallest problem or defect. The length of the warranty will also vary. As your warranty will protect you from unforeseen issues, it’s worth it to do a little research if you’re buying your car battery before it’s necessary.

Convenience in All Weather – When it comes to batteries you hear a lot about amps and overall power, but cold cranking amps matter, too. The higher the CCA number is, the better. That’s because the cold cranking apps are what enable your car to start in 0-degree weather. Having a new battery often means that you don’t have to worry if your car will start no matter what the weather is like.

Keep in mind, that every car can use a certain type of batteries. Most online stores will allow you to put in your make, model, and year so they can only show you the batteries that will work for your car. Brick and mortar stores should also ask you this information in order to help you find something that will work best for your situation.

How We Chose the Best Car Batteries

Here at Educated Driver we take car maintenance very seriously. We try to only mention the best products in a list like this. To come up with the best auto battery options for this list we spent plenty of time testing car batteries of all kinds. We also took into account things like manufacture information, brand name recognition, and third-party auto battery reviews.

Maintenance Free vs Low Maintenance – Many of the best rated car batteries are maintenance free. This means that other than checking for wear and tear your interaction with the battery is minimal. Once it’s been installed you can basically forget about it. Low maintenance is still fairly easy to handle but does require a little more work. We considered what would be required of the user after installation to ensure that the best car batteries on this list would suit the most people possible.

Value & Warranty – Some believe that the best rated car batteries need to cost more. That’s simply not true. While there are some budget options that will wear out before the high-performance car batteries, on the whole price does not dictate the quality of the product. We attempted to find car batteries that gave you the most bang for your buck. Also included here is the length of the warranty. All car batteries offer some sort of warranty, so we factored in the length of the warranty and what you would be protected against, if you ended up needing to use it.

Brand Recognition – This doesn’t mean everything, but batteries aren’t cheap. Often when you look up the best rated car batteries, you’ll see the same names repeated. These are the brands that are consistently putting out quality products. We looked at a variety of the top names and others that were newer to us in order to choose the best car batteries for this list.

Car Battery Reviews – Finally, we considered verified, third-party car battery reviews. While our own research was important, we wanted to offer a clear look at the best car batteries on the market. This meant considering what others felt about their battery. We looked for car battery reviews that detailed a variety of situations to provide a clearer look at the ability of each battery we considered.
