The best car batteries

There are many different types of batteries available, but we’re going to focus on the ones that fit the widest variety of passenger vehicles. Some of the best car batteries also work well in commercial applications, so it’s important to know the difference. We’re also going to talk mostly about absorbed glass-mat (AGM) batteries, which are different than the flooded batteries we think of when talking about car parts. In AGM batteries, the electrolyte solution is absorbed into fiberglass matting. This packaging solution makes them more resistant to vibration and leaking than the more traditional (and cheaper) flooded batteries found in the vast majority of cars on the road.

You should also ensure that the battery you pick will physically fit into your vehicle. It’s possible to find different sizes, even within the same type and brand of battery, so be sure you’re picking one that’s right for your car.

Optima RedTop Batteries

Optima conveniently colors its batteries, with the red tops being made for most types of stock vehicles. The Optima batteries are better for vehicles with electronics and all sorts of “things” to power, and they are made with extra shock resistance in place that makes them work well in high-performance vehicles, or those that frequently travel off-road.

The RedTop can be mounted in any position, is maintenance-free, features fast recharging, and has up to fifteen times the vibration resistance of a traditional battery. AGM batteries are typically much more expensive than regular batteries, and this one’s no exception.

ACDelco ACDB24R Advantage AGM Battery

Like the Optima, this car battery is an AGM, which means it’s longer-lasting and more powerful than a standard battery.

Also like the Optima, this Aldeco ACDB24R battery costs quite a bit more than what you’re used to paying for a standard unit. ACDelco batteries are original equipment on GM and many other vehicles, but this one will fit and work with vehicles of almost any type.

Exide Edge FP-AGM24F Flat Plate Battery

Exide’s Edge batteries benefit from secure, non-spillable AGM construction. They’re ideal for vehicles that are frequently in stop-and-go traffic. The model we’ve selected provides 710 cold-cranking amps, so it won’t let you down when the temperature dips.

The Exide Edge FP-AGM24F is one of Exide’s most affordable AGM models, but it’s more expensive than many other batteries.

Bosch S6508B Flat Plate AGM Battery

Bosch makes more than just tools and dishwashers, and its AGM line of car batteries is among the best.

The Bosch S6508B features 710 cold-cranking amps, it weighs 47 pounds, and it should outlast conventional car batteries by up to two times. The company’s roadside assistance program is available to buyers, too. To sweeten the deal, Bosch will replace the battery free of charge if it fails within four years of purchase.

How much does an electric car battery cost?
Two Electrify America Charging Stations.

Electric cars are often hailed as being cheaper to operate and repair than gas-powered cars. It makes sense — on the operation side, you only need to pay for electricity (not gasoline), and on the repair side, there’s no motor or transmission to deal with.

But electric cars have other costly repairs, and while in total they do generally cost less than repairs for gasoline cars, it’s worth knowing about the potential costs ahead of time. Perhaps the most obvious, and one of the most costly, has to do with an electric car’s battery. After all, while all cars have batteries, those in electric cars are far bigger and more advanced — and thus can cost quite a bit to replace.

The Sony Honda Afeela car is peak CES, and I’m totally here for it
Yasuhide Mizuno, representative director, chairman and CEO of Sony Honda Mobility Inc., introduces the Afeela EV.

Everyone knew what was coming. Sitting a half-dozen rows back at the Sony press conference the afternoon before the CES show floor actually opened, you could tell by the layout of the booth — drastically different from what Sony had in previous years — that something big was going to be wheeled out.

That something, of course, was a car. It wasn't a big secret. Folks were talking about it on the bus ride to the Las Vegas Convention Center from the Mandalay Bay Convention Center, where a good chunk of the work happens before the CES doors are open. Folks were talking about it — in all sorts of languages — in the long line down the hallway that separates two of the bigger halls at the LVCC. English. Japanese. Spanish. So many others. And you didn't have to actually know what they were saying to know what they were talking about.
