In our guide to the best car batteries of the year, we highlight the top-rated choice in each size we test. With this list we’re looking at value, factoring in performance alongside price. 

“The best value may be in choosing a strong performer that can be had for much less than the cost of the top battery,” says Paolo Fu, who oversees the testing of car batteries at Consumer Reports. If you’re interested—and unencumbered when it comes to price—you can look at our complete list of car battery ratings, too.

Below, we present the best car batteries for the money in seven different sizes: Group 24/24F, Group 35, Group 47 (H5), Group 48 (H6), Group 49 (H8), Group 51R, and Group 65. These numbers indicate size in the same way AA, AAA, C, and D indicate the size of batteries you’d use to power home electronics.

It’s important to note that batteries are also priced differently based on size. Larger-sized groups 48 and 65, for example, cost more because of the materials needed to make them, averaging $198 and $191, respectively. Smaller batteries like the 24/24F and 51R average $150 and $174, respectively.

Before you buy a new car battery, know the correct group number for your vehicle, which varies depending on make, model, year, and engine size. Batteries are defined by physical size, type, and placement of the terminals, as well as mounting style. The basic specs for a replacement battery can be read from the battery currently in your car, but if you bought the car used, it is wise to consult the owner’s manual to ensure the correct battery size and type is used. Be sure to replace your battery with one that’s from the same group so that it will fit its tray and the leads will connect properly.
