Best Car Batteries of 2019

We tested 150 of them this year to separate the positives from negatives

Installing the best car batteries.

At Consumer Reports, we test 150 car batteries every year in our lab, charging and discharging them thousands of times to find out how long they’ll last.

We put them in a freezer to see how they’ll perform at 0º F, and we track how long they’ll last if you leave your car's headlights on.

More on Car Batteries

Some of our top-rated batteries cost less than many of their competitors, says John Banta, CR's test engineer for batteries.

“Price doesn’t necessarily mean better performance,” Banta says. “We’ve got some batteries that are relatively cheap that score very well.”

Here you'll find the top-performing battery in each category we test: Group 24 & 24F, Group 35, Group 47 (H5), Group 48 (H6), Group 49 (H8), Group 51R, and Group 65 car batteries. They are ranked by Overall Score. 

And we have advice on the best places to buy a replacement battery. You'll also find information on how to know what type of battery your car needs and how to choose the right replacement battery.
