5 Best AGM Car Battery (Tested) 2023

An AGM battery is a car battery that uses AGM cells instead of lead-acid batteries. These cells are highly resistant to corrosion and have a long life cycle. The cells are also lightweight and easy to handle.

An AGM battery is designed to work in a vehicle that has a 12V DC power system, such as electric vehicles, hybrid vehicles, or electric motorcycles.

There are two types of AGM batteries: sealed and ventilated. A sealed AGM battery is the most popular because it has a higher energy density, is more durable, and lasts longer than a ventilated AGM.

AGM batteries can be used in any vehicle with a 12-volt power system, such as electric vehicles, hybrid vehicles, electric motorcycles, or electric cars.

An AGM battery is a long-lasting, lightweight, and safe battery that can last up to 20 years. This battery is also easy to install, maintain, and replace.

We love the Odyssey PC680 Battery from Odyssey Battery. This is our number one recommendation because of its incredible warranty, high capacity, and great price.

It has a very good warranty, only two years, and covers full replacement. That’s much better than other batteries offering only a pro rata replacement coverage.

Its high capacity is another reason why we love it so much. It has a capacity of 170 CCA, enough to power most of your electronics.

3. XS Power D3400

Staff Pick
3 20

XS Power is a small battery company based out of Southern California, offering batteries for all sorts of applications. They make various batteries for all sorts of things, including solar, marine, RV, forklifts, and even electric cars.

The XS series of batteries are designed for large-scale power applications. They’re not meant to replace your car battery, but be used as a backup when you’re away from home or at a job site. For example, you could use this battery to power a remote switch or a remote control for your lights.

This XS battery is designed to provide 3,300 amps at 12 volts and has an internal resistance of 0.1 ohms. The internal resistance of a battery is how it resists current flow, and lower internal resistance means it can handle more current.

The XS battery is sealed, meaning it’s spillproof so that you can fill it up at the source, and it won’t leak. It’s also vibration-resistant, which makes it great for vehicles.

The XS battery is also sealed, so it won’t lose its electrolyte if it gets wet, making it great for RV or marine use. It also features a valve regulator, which reduces the risk of overcharging.

The XS battery is designed for 12-volt use, perfect for RV, boat, and car batteries. It’s made for mounting in almost any position, which means you can place it in any location, and it’ll still work.

The XS battery is rated for 3,300 amps at 12 volts, and the capacity is 65 Ah. It’s built with AGM technology, which means it has an absorbent glass mat. This material absorbs moisture and prevents it from shorting the battery out.

While AGM batteries are generally more expensive than standard batteries, they are more environmentally friendly, and resilient.So if you’re looking for a high-quality, long-lasting, affordable battery, buy the XS.


  • Superior performance in all forms of racing
  • Wide selection for a variety of racing needs
  • Top quality and consistent performance
  • Easy to install and maintain


  • Higher cost than traditional lead acid batteries
  • Limited availability of AGM battery chemistries
  • Not suitable for vehicles with weak electrical systems

4. ACDelco 48AGM Professional

4 18

ACDelco makes great batteries for power tools, but I’ve found their batteries to be a little lackluster.

These Gold batteries are no exception – they’re made with high-density negative paste, which improves performance and extends battery life. The battery comes with a 7-year warranty, which covers the replacement of the battery.

They’re sold at Costco and are available in sizes 6Ah, 9Ah, and 12Ah. I bought a 12Ah battery because I wanted to go big and see if it’d work.

The battery is heavy, and the packaging makes it look like a power tool, but it’s actually for a pool heater.

I’d change a few small things about the packaging: the battery isn’t labeled properly, and the instructions could be a bit clearer.

I had to dig through the packaging to figure out how to get the battery in and out of the enclosure. I ended up pulling the whole thing apart and pushing the battery in.

Once it was in, I used the included clips to attach the battery to the unit. The clips are sturdy, but I would’ve liked to see a larger hole for the clip to fit into.

The battery is easily removable, so you don’t have to worry about damaging it. A vent cap on the bottom also lets out excess gas and prevents acid from leaking.The included installation instructions were pretty basic and didn’t cover anything in depth.

The only thing I did differently was to use a pair of pliers to pull the battery out of the package. I wasn’t sure if there was a way to remove the battery without the pliers, but I didn’t have any problems doing it.

Overall, the Gold 48 is a solid, reliable battery. I’m impressed by the performance, and the warranty is very generous.


  • ACDelco Professional Automotive AGM Batteries have high cycling capabilities.
  • They are remarkably charge-receptive.
  • They are necessary for ‘start/stop’ vehicle applications.


  • The Absorbed Glass Mat design is 100% leak
  • Oxygen recombination reduces water over time.

5. Delphi MaxStart AGM

Budget Pick
5 15

Delphi is the name to trust if you’re looking for a premium automotive battery. It’s a well-known brand, and they’ve been around for over 50 years.

They’ve also designed some of the most popular batteries on the market. Their group size 94R (reverse terminal) battery is one of the highest capacity batteries available, delivering 800 CCA (cold cranking amps) and 140 R. C. (reverse capacity).

I’m sure you know how important cold-cranking amps are, but the reverse capacity is a bonus. I think it’s safe to say it’s a premium battery.

The battery is backed up with an industry-leading 20x vibration resistance, meaning it can handle 20 times the amount of vibration you can put it through compared to a regular automotive battery. This makes it extremely useful for heavy equipment, mining, and agricultural vehicles.

These batteries also feature superior corrosion resistance and are sealed with a manifold venting system that helps reduce gassing and corrosion.A 2-year warranty and a lifetime warranty on the battery also back them.

It’s pretty clear that this is a premium battery, and a great warranty backs it up. If you want a quality battery that will last you for years, get the Delphi BU9094R MaxStart AGM Premium Automotive Battery.


  • Long cycle life.
  • Good CCA.
  • Vibration resistant.
  • Twenty times the vibration resistance.


  • Pricey.
  • It may only be compatible with some vehicles.

Best AGM Car Battery

If you own a car, you know the importance of a good battery. But what happens when you don’t have access to a charger and your battery is dead? You may only realize the danger of driving with a working battery once it’s too late.

Many factors can affect the life span of your car battery. For example, the climate can affect battery life. Colder temperatures can decrease the life of a battery.

So, you first need to ensure you’re in a climate-controlled environment where you can charge the battery. Consider bringing the car in for service if the problem persists.

Another factor to consider is the vehicle itself. Some cars use an inverter, which converts the power from the battery to alternating current (AC), and some cars use direct current (DC), which is converted from the AC to DC.

Your car’s type may also impact the life of the battery. For instance, ensure you’re using the right battery for your vehicle. If your car uses a 12-volt system, you should use a 12-volt battery.

There are several different types of batteries on the market today. For example, lead acid batteries are inexpensive, but the amount of charge and discharge they can handle is limited.

Other batteries include sealed nickel-cadmium, lithium-ion, and nickel metal hydride. These types are more expensive but offer a longer charge time and more powerful performance.

The type of battery you need depends on what you need it for and how much you need it to run. Consider a more powerful battery if you want a longer run time.

The type of battery you need also depends on how often you’ll need it to recharge. For instance, a sealed nickel-cadmium battery is perfect for a car you use once a week.

On the other hand, a lead-acid battery is ideal for a vehicle that you use daily.So, before shopping for a battery, make sure you know what type you need and what your needs are.


In conclusion, it’s hard to say exactly how much is enough for your needs. There are a lot of different factors to consider, so it’s going to take some trial and error to determine what works best for you.

We’ve outlined some of the most important things to remember, but this is just the tip of the iceberg. As with all things, there’s a good chance that something else will work better for you, but hopefully, these tips will help you find a solution that works for you.
