AGM batteries were a military gadget in the 90s. It was a choice for the military basically because it’s surprisingly lightweight and totally spill-proof. AGM stands for Absorbent Glass Mat, sucks in the sulfuric acid making it spill-proof. Which was rendered as impossible before AGM came to light?
Being able to keep the acid in and not vomiting it out wasn’t the only thing that got this such market share. It has significantly lower internal resistance as compared to batteries adhering to other technologies. Meaning that the best AGM battery can pump out more amps than the others.

If you are looking for the spill-proof or leak-free batteries, then these Lead Acid batteries are the best option for you. Optima batteries are usually of Lead-acid type. But as they are always sealed to be leak-proof, you can not repair them when they have some issues.
Deep Cycle
Usually, a deep cycle battery is a type of Lead-acid battery that is manufactured to be deeply discharged consistently utilizing almost all of its capacity. For greater durability, you can always rely on them. For your EVs or golf carts, these are the best options for you.
Wet Cell
For budget buyers, a wet cell battery is an ideal choice. But the build quality is usually cheap. So you may face more complications and should expect regular servicing or maintenance.
Durability
The average lifespan of AGM batteries is between 1 to 10 years. But most of the manufacturer provides the warranty of 3 years. Some of the sealed batteries are devoid of any kind of maintenance or servicing. So, they tend to last long without any servicing. That’s one of the main reasons why people rely on AGM batteries.
Reserve Capacity
Reserve capacity is actually the total amount of time that your fully charged battery will be able to provide power to the functions of your car before it runs out of juice. So, if you’re out for a drive, having a break and listening to the radio, this reserve capacity will determine how long you will be able to last.
Cold Cranking Amps
One of the key features of this AGM battery is that they work efficiently in any kind of weather. Cold Cranking Amps refers to the ability of your battery to start your car at a low temperature. You should prefer the batteries with no less than 720 CCA. But living anywhere near Alaska or Dakota prefers 800+ to avoid getting flat.
Applications
To power your vehicle that has got a lot of electronic or plug-in accessories, you can depend on deep cycle batteries. For the huge power demands of your vehicles, these AGM batteries are more preferable. Audio systems, GPS, DVD players, and other electronic tools of your car increases demands in this battery.
Start-Stop Vehicles
For the start-stop vehicle technology, most users favor AGM. When the engine is turned off, all the electronic accessories of your car count on your batteries. At that time, your car requires a stronger battery than the typical Lead Acid batteries. With better cycling potential, the AGM battery remains the best option.
Vibration and Leak Proof
The batteries are designed in such a way that it hardly leaks any chemicals or acids and spilling is out of the question. Besides, the resistance to vibration is up to the mark. So you will be able to place these batteries in your car as per requirement. But ensure that you get better mounting flexibility with the one you choose.
