Feb 26, 2021   Pageview:91

Changing your car's battery can be a bit frustrating, particularly if you don't know what sort of battery you have to buy as there are so many types of car batteries out there. But have you heard about the AGM battery? Nowadays, AGM batteries are becoming a top preference for most people!!

Basically, an AGM battery is a car battery designed for two purposes: providing effective amp bursts and running electronics for a long time. And here's the huge deal: they seem to last longer than a standard flooded battery. These batteries also have valves that control the amount of hydrogen and oxygen gas and allow them to escape while charging. They come under a wider group of valve-controlled, lead-acid (VRLA) batteries, usually used for long-term power uses.

If you want to know more about AGM batteries, we came up with this comprehensive guide that entails how AGM car Batteries are better, AGM Battery brands and is it really worth to buy so that you can make your decision best.

On that note, Let's commence!!

Are AGM car batteries better?

One of the most often asked questions about AGM car batteries out there is whether they are better or not. So, take a look at how the AGM car batteries are better.

?They are durable

The prolonged lifetime is one of the major benefits of these AGM batteries. For instance, an AGM car battery should last up to two to three times longer than a flooded one. The primary reason AGM batteries are so durable is that they are deep-discharge resistant. They could also be charged without being used for 6-8 months since they have an incredibly low self-discharge rate.

?They are spill-proof

This battery is unshrinkable, as the lead-acids are absorbed by the glass mat. Even when you change the battery upside down, the electrolyte does not pour out. As such, there is no possibility of electrolyte burns. In addition, AGM batteries do not release gas when charged, so you don't have to be concerned if they are appropriately ventilated while charging. In cold temperatures, they can also operate well, which is not the case for normal lead-acid batteries.

?They are more efficient

There is a unique advantage to AGM car batteries: they charge up to five times faster than flooded batteries. In addition, compared to flooded batteries with a 50 percent discharge depth, the AGM technology generates an 80 percent discharge depth to maintain the same cycle time.

?They are easy to maintain

Another advantage of the AGM battery is that it can be used instantly. As their cell counterparts have flooded, apart from recharging them before use, these batteries do not need any further care. As a result, for the customer, both the installation and maintenance are saved by AGM batteries.

?They have high-power output

Due to their design, the AGM batteries have minimal inner resistance. This enables them to supply enough power when needed, such as when it is necessary to start a battery. Because of this feature, batteries respond to charges better than any battery on the market.

?They don’t build Sulfation

Sulfation is the property of lead-acid batteries in which lead sulphate crystals in the cells are eventually produced. It is the cause of lead-acid battery failures in most cases. Sulfation happens more when the battery is not fully charged, and the crystals are continuously building up on the plates. Thus, to prevent the sulfation of other forms of acid batteries, it is essential to charge them every six months. Sulfation in AGM batteries is, however, greatly decreased and can also be kept for long periods without a recharge. So, just sit back and look at them to find the right one for you.

What is the best AGM battery brand?

Your heart is the organ that makes all of the body's other parts functioning. So, what will happen if it gets messed up? Everything will malfunction, so the same applies to the car battery. Once it stops working, it will interrupt all the other parts of the car.

So, you have to install a new battery. Yet, it's frustrating and deceptive for customers looking to get the right battery by watching all the flashy ads. But don't worry! To make it simpler for you, we've picked the best AGM battery on the market. So, just sit back and look at them to find the right one for you.

?Renogy Deep Cycle AGM Battery

This 12V deep cycle AGM battery has an impressive power of 100Ah. Besides that, it has a maximum rate of 1800 CCA. For charging, the operating temperature range ranges from 32-104F° and for discharging 5-122F °.  A self-discharge rate is maintained below 3 percent each month at 77°F.

?Optima Batteries DH6

This 12V deep cycle AGM car battery has an impressive power of 100Ah. Besides, in the class, it has a maximum rate of 1800 CCA. For charging, the operating temperature range differs from 32-104F ° and for discharging 5-122F °.  A self-discharge rate is maintained below 3 percent each month at 77°F.

Is it worth buying an AGM battery?

Yes, it is totally worth buying, as mentioned above, how AGM car batteries operate and why these batteries are better. You could easily afford to spend 25-40% more on a battery that would last at least twice as long, even endure some rough roads, and recharge more quickly on short runs. And for something less likely to blow up in your head when you try to jump-start your car well, it's more worth it to buy AGM car batteries.


AGM batteries last for a long time. Just make sure that no less than 60% of the battery is discharged. End up buying a battery charger or battery tender to sustain the capacity of the AGM battery in storage if you are preparing to store your vehicle for the winter. Indeed, an essential part of selecting the right AGM battery is not just the brand but also how you take care of the battery. If you find cracks or signs of wear on the outer shell, make sure to fix the battery ASAP!!!
