Most people are familiar with lead-acid automotive batteries. They are very popular and very inexpensive. However, a new type of battery called AGM batteries is quickly becoming the go-to car battery of manufacturers, tuners and car enthusiasts. This is mainly due to their performance, durability and low flow rate. The first AGM batteries were invented by the military for military vehicles and military aircraft at the beginning of the 1980s. Because this type of battery is so superior to the traditional lead-acid battery in terms of both performance and durability, it became commercially very successful.

AGM car battery reviews

AGM Batteries Pros

  • Powerful: Compared to other battery types, AGM batteries are powerful and deliver many amperages, making them ideal for demanding cars such as sports cars and muscle cars.
  • Low flow rate: A good auto AGM battery can run up to 8 months at idle without discharging. This is simply not possible with a conventional lead-acid battery.
  • High Cold Crank Amps: Most AGM batteries typically have a high CCA value, making them ideal for use at low temperatures.
  • Very durable: Since the glass fiber and wire mat inside the AGM battery is very tight, there is no movement. This makes it less susceptible to wear and vibration damage.

​How to Buy an AGM Car Battery

Compatibility

Even if the AGM battery is technically universally compatible with most vehicles, you should inquire whether the AGM battery you are interested in works with your vehicle or not. Pay particular attention to the current per hour (AH) and make sure it is not too high and suitable for your vehicle.

This is because a battery with a high AH value requires a larger alternator or more time to charge. If you do not use your vehicle, long enough or have a small alternator than buying an AGM battery with a high amperage per hour is counterproductive and in your case a disadvantage.

Reserve capacity

Reserve capacity is one of the most important aspects when buying an AGM battery. Basically, reserve capacity is the number of minutes that a fully charged AGM battery will discharge at normal temperature exactly 25A of current until the battery becomes ineffective and generates a voltage of 10.5V.

Compared to a normal lead-acid battery, the AGM battery has a remarkably high reserve capacity because it is more robust. In general, you should expect a reserve capacity of at least 100 minutes from an AGM battery.

However, this value still depends on your usage. If you do not consume as much electricity in your vehicle, you can safely drive with an AGM battery with lower reserve capacity.

Cold crank amps

In short, the CCA or cold crank amps is the battery’s ability to generate current at cold temperatures. The higher the CCA, the more advantageous the battery is in winter because it is a heavier battery capable of starting the vehicle engine immediately regardless of a low temperature.

In general, an AGM battery of more than 600 CCA is sufficient for people living in cold areas. On the other hand, if your region is generally hot, then you do not have to worry so much about the CCA value in your AGM battery.

Lifetime

Since the AGM battery is an expensive purchase overall, you will want to buy it as rarely as possible. In most cases, battery life is an important factor as it directly determines the amount of money you will spend.

Even if the AGM battery is more robust than the normal lead-acid battery, it must still be changed regularly at certain intervals. Most manufacturers indicate their battery life directly on the battery itself. It ranges from one year to 5 years.

The longer the life of the AGM battery, the better, as it designates a more powerful battery with a lower discharge rate.

However, you must also consider the CCA value if applicable and the rated power if you need it. You should not sacrifice power or CCA for life as you will eventually need to replace all batteries, no matter how powerful or heavy they are.

Brand

When buying an AGM battery, it is recommended to use a brand model. This is because brands generally have better quality control and use higher quality materials in the construction of their AGM batteries.

In addition, you get a rock solid warranty with a good brand, while a nameless battery usually has no warranty.

Conclusion

As we have seen, the AGM battery is an unbeatable battery when it comes to performance, reliability and durability. One of the best things about this type of battery is that it costs almost the same as a high-quality lead-acid battery, but is so much better, especially for those who drive in cold weather.

In addition, this type of battery is ideal for those who do not drive their car for an extended period of time as it has a very low discharge rate. A normal AGM battery should last up to 8 months or more without charging.

Finally, our car AGM battery review above lists some quality models. If you still have not found a suitable battery for your car, we recommend you read this review again.
