You must know this, but your car needs a battery to run properly. A dead battery means a car won't start, but various electronics in the car won't work properly either, including overhead dome lights, the radio, and even some security features, like door locks or alerts. So, it's in your best interest to ensure your vehicle's battery is in tip-top shape at all times. It's especially important if your car or vehicle sits unused for long periods. A trickle charger can help keep the battery powered in those situations, or worst case, a portable jump starter can help you get it going. But eventually, you're going to need to replace your battery, and it will help to know the best car battery brands out there so you know precisely what to replace your old one with. Let's discuss.
AC Delco
In operation for more than a century, AC Delco has been recommended as "the only batteries" for GM vehicles. You'll find them at retailers like AutoZone, O'Reilly Auto Parts, Amazon, and even some Walmarts. They're reliable, reasonably priced, and come with a good warranty, 18 months or above, depending on where you buy. A great AC Delco battery to call out is the Advantage series.
Bosch
Bosch is a solid mid-grade battery provider both in quality and price. They do have some affordable options, but their premium lines are still reasonably priced, with several tiers available for a wide variety of vehicles. The downside is that Bosch batteries are not carried by all retailers like some of the other options on our list, but you can find them online. You can also visit a Bosch service center if there's one near you. Callouts are the S4 to S6 series and the T4 to T6 series. We will say the brand's four-year free replacement warranty is unmatched.
