AGM batteries are more and more often used for powering office and home devices. What is the thing that distinguishes this technology, and with which types of equipment can it turn out to be a bull’s eye? Get to know the secret of AGMs and check out what they can prove useful for!
In this article you will find out:
- what an AGM battery is and how it works,
- which devices work with its assistance,
- how to charge an AGM battery correctly.
What’s an AGM (Absorbent Glass Mat) battery, and how does it work?
VRLA (Valve Regulated Lead) is a group of batteries including gel batteries, as well as ones equipped with the AGM (Absorbent Glass Mat) technology. These two solutions are often applied in a single product – such as in the case of the Green Cell batteries.
The well-thought-out design of the AGM batteries prevents air and pollution from getting inside of the battery. The valves open when there’s high pressure inside of the battery, owing to which the risk of the battery getting bulged and bursting – and thus getting permanently damaged – disappears.
Glass fiber has been used in AGMs, owing to which the electrolyte is tightly sealed and secured. Due to this type of filling the interelectrode space, we don’t have to worry about the electrolyte leaking from a mechanically damaged battery. Owing to such a solution, AGM can safely operate in any position, this including a horizontal one. Glass fiber also has influence on a significant increase in the number of cycles (even up to a four-time longer life in comparison with traditional batteries). Multiple charging and discharging of your battery are possible without influencing its performance parameters.
And thus, the AGM batteries are maintenance-free, fully sealed, resistant to shock and impact, which is what also makes them do well when working in difficult conditions. Let’s find out which devices will find them useful!
The 9 applications of the AGM battery divided into buffer and cyclic operation
We can distinguish two operating modes of the AGMs, which will find their application in the case of other types of devices. In buffer operation, these batteries are used as a specific kind of protection charged with a small current. They’re an emergency power supply – the battery’s installed inside the device and connected to a power supply.
Here are the applications of an AGM battery in buffer operation:
- alarm systems,
- UPS power supplies,
- cash registers,
- emergency lighting.
In cyclic operation, AGM are used as a main energy source. This is the mode in which the batteries are discharged and recharged when necessary.
AGMS work in a cyclic fashion in the following cases:
- cash registers,
- wheelchairs and golf carts,
- cleaning machines.
Start-Stop Vehicles, Large Audio Systems, Heated Seats and Other Electronic Accessories
If you’re looking to power a vehicle with numerous electronic features or plug-in accessories, you should consider a deep-cycle battery or a battery made with advanced technology like AGM.
AGM batteries are a great premium choice for high-end and advanced fuel-efficient vehicles with large power demands, and for people who seek greater reliability and longer life in auto batteries. Electronic features such as DVD players, GPS, heated seats and audio systems all add to the demands on a battery.
AGM Battery Benefits
- Up to 2x longer life than standard flooded batteries
- Designed for harsh climates and demanding conditions
- Handles high electrical loads
- Quickly recharges and extends cycle life
- Ideal for start-stop applications
- Vibration resistance
- Nonspillable and maintenance-free
- Greater mounting flexibility
AGM Battery Disadvantages
- Higher initial investment
In the offer of Battery, you’ll find a wide selection of AGM batteries which can be used both for buffer, and cyclic operation. They ensure safe usage, and owing to the self-regulation function – they can give you even up to 5 years of maintenance-free operation!
AGM batteries – how do you charge them?
Gel and AGM batteries need to be charged with a constant voltage method. The charging should proceed in two phases – first, direct current charging, and then, charging with maintaining constant voltage.
For this specific task, it’s worth to choose a charger which automatically recognizes the cell type. Owing to this, you will avoid the risk of your battery getting destroyed by inappropriate charging. This is why the Green Cell charger is selected so often – it’s a universal charger for AGM batteries, as well as for lead-acid batteries. Its wide compatibility makes the device perfect for charging batteries, e.g. UPS power supplies, alarm systems, and quads with various voltage (2V/6V/12V). Moreover, this equipment guarantees efficiently charging batteries up to 20Ah with a full protection package: against short circuit, and against getting overcharged. This product also detects when the clamps are connected incorrectly, owing to which you can react quickly and properly re-connect them.
AGM BATTERY VS GEL
Another popular alternative to flooded and AGM type batteries is the Gel battery. A Gel battery is still maintenance-free, its cells are sealed, and it uses a recombination process to prevent the escape of its gasses. What varies with a Gel battery is the electrolyte itself is a thixotropic gelled sulfuric acid.
When comparing a Gel battery to an AGM battery, you will see that the Gel battery’s rated capacity will decline much faster than an AGM battery’s as the ambient temperature get colder (below 32 degrees F). A Gel battery is also does not perform as well in high rate or starter applications as an AGM, which is why you don’t see Gel power sport batteries. On the plus side for Gel, it is more acid limited, giving it a slightly longer service life in some applications. Power Sonic offers Gel batteries in our DCG (Deep Cycle Gel) and our 2-volt OPzV Tubular Gel lines.
Before you buy a new AGM, make sure to check the parameters of the battery you’ve been using previously – you’ll find those on the nameplate on the side of the casing. Once you get familiar with them, you can find a matching AGM on their basis by using our search engine.
