Buying Guide For The Best AGM Batteries

Whether you have a car, truck, bike, boat, or even an aircraft, you can simply get an AGM battery for starting their engines. This is possible as AGM batteries are highly powerful and offer quite high current output for cranking the engine.

Thus, a few of the best AGM batteries are already discussed up above. Even though these AGM batteries have been stated along with their features and options, some of you might want to know more. In that case, consider going through the following detailed buying guide for the best AGM batteries:

1. Voltage

Starting with one of the most basic yet highly important factors to consider while getting an AGM battery, you should consider its voltage output. This is to ensure that the voltage of your AGM battery is compatible with your vehicle and a car battery replacement is quick and simple. Therefore, all AGM batteries out there, including the ones stated above, offer 12-volt output for proper compatibility.

2. Capacity

Apart from the voltage output of your AGM batteries, considering their capacity is also quite important. It ensures that the battery can last for a long enough time even if it was not recently charged. Thus, you can find most AGM batteries with a capacity rating given in Ah. This includes ratings like 45 Ah, 60 Ah, 100 Ah, and even 125 Ah. Out of all these battery capacity options, the highest battery capacity of 125 Ah is going to last for the longest, making it ideal for heavy-duty usage.

3. Cold Amps

There might be many cases where the battery of your vehicle might not be able to start the engine on a cold morning. To prevent such an issue, make sure to check the cold amps rating of your battery.

This simply tells you about the maximum amps your battery can offer even when it is cold weather outside. For the same, you can find cold amp ratings like 500 amps, 750 amps, and even 1000 amps in some cases. And as you would expect, the higher rating is the best one for larger sized engines which require a powerful battery for engine startup.

4. Battery Design

Even though all of the batteries given up above are AGM batteries, they may use a slightly different internal design. This primarily includes lead acid AGM batteries and sealed lead acid AGM batteries. While both of them offer the same performance, a sealed lead acid one offers slightly better spillage protection.

5. Warranty

In comparison to other battery types, AGM batteries are already quite reliable for long term usage. Although, to ensure that your specific AGM battery is reliable enough, make sure to check the warranty offered by your AGM battery. Thankfully, in most cases, you will find either a 1 year long or a 2-year warranty with your AGM battery. However, if you want something highly reliable, then a few options also offer a 3-year warranty.

AGM Batteries – FAQs

1. How does an AGM battery work?

Ans: AGM batteries work by storing electrical energy through the chemical reactions of lead and sulfuric acid. The absorbed glass mat serves as a separator between the positive and negative plates, immobilizing the electrolyte.

2. Where are AGM batteries commonly used?

Ans: AGM batteries find applications in various fields, including automotive (for start-stop systems), marine, RVs, UPS (Uninterruptible Power Supply) systems, solar power storage, and other deep-cycle applications.

3. Are AGM batteries maintenance-free?

Ans: Yes, AGM batteries are generally maintenance-free. They don’t require regular topping up of electrolyte levels because the electrolyte is absorbed in the glass mat separator.

4. Can AGM batteries be used as a car battery replacement?

Ans: Yes, AGM batteries can be used as a replacement for traditional flooded lead-acid batteries in vehicles. They are particularly popular in vehicles with advanced electronics and start-stop systems.

5. How do AGM batteries compare to other types of batteries?

Ans: AGM batteries offer advantages over traditional flooded lead-acid batteries, including a maintenance-free design, resistance to vibration, and suitability for deep-cycle applications. They are also more cost-effective than some alternative technologies like lithium-ion batteries.

6. Can AGM batteries be recycled?

Ans: Yes, AGM batteries are recyclable. It’s important to dispose of them properly at recycling facilities to ensure that the lead and other materials can be reclaimed and reused.

7. Can AGM batteries be charged with a regular battery charger?

Ans: Yes, AGM batteries can be charged with a regular battery charger, but it’s recommended to use a charger specifically designed for AGM batteries to ensure optimal charging and longer battery life.
