There are several variations between battery models available on the market and it’s time for you to meet one of the most traditional and reliable: the sealed battery. Check out how it works: The sealed batteries are also known as lead-acid batteries, divided into two types of technology, Ventilated – Conventional and EFB (Free Electrolyte) and VRLA – AGM and Gel (Immobilized Electrolyte).
What models are there?
It is possible to find the sealed batteries in different voltages and capacities.
Sealed 12V battery is standard, but there are more options, such as 2V, 6V, and 24V. As for the storage of electrical charge, we have smaller batteries, ranging from 1.3 Ah (Ampère-Hour), up to 2000 Ah – which may have larger capacities depending on the project.
There are some smaller batteries that are used to power any electronic device, such as computers, in case of a power failure. It is very common to find equipment that uses a sealed 12 V 7Ah battery.
What are the advantages of opting for a sealed battery?
Below, you will learn more about the features and advantages of choosing a sealed battery:
Has lower risk of leakage
One of the advantages of opting for a sealed battery is that it has less risk of acid leakage, as there is no element access to the outside of the battery. In this way, the risk of damage to nearby electronic equipment is greatly reduced.
There is no need for any maintenance; the sealed battery is designed with the proper amount of water to last for the life of the part.
Which buyers or businesses benefit most from a sealed battery?
The most diverse types of batteries benefit from a sealed battery technology, and Moura has the most complete line, check it out:
Clean line sealed batteries were designed for stationary applications such as no breaks, GTDE, oil, and gas. They have a greater resistance to cycling, temperature and can remain in a fluctuation regime for much longer than ordinary batteries.
They are also certified for telecommunications applications, as they have the highest levels of demand. In addition, they are also certified by Inmetro. These batteries have a safety system that allows them to be used in the same environment as electronic equipment. They are also adapted to the tropical climate, being able to operate at high temperatures.
VRLA line of stationary batteries is ideal for controlled environments. It has a longer service life, greater durability when placed in controlled temperature environments (up to 25°C), more instantaneous power, as they have low internal resistance and ensure greater high current load acceptability.
VRLA technology reduces the release of gases and allows the part to be placed flat. The VRLA sealed battery is also versatile for use in remote locations and is guaranteed power.
In addition to this stationary battery being used in the central telecommunication station, it is used for medical and hospital equipment, 24-hour ATMs, cashiers in stores and supermarkets, oil platforms (offshore), reclosers, and UPS/No breaks.
VRLA technology in the AGM automotive line
The AGM battery (Absorbent Glass Mat) is very suitable for high-performance cars that need even more battery. The acronym means “ absorbent fiberglass blanket ” and refers to the total absorption of the acid solution (electrolyte) in its separators. Therefore, the battery does not degrade and does not spill liquid as it does in a flooded battery.
This happens because of the AGM separator that keeps the electrolyte in suspension, keeping it in constant contact with the active material of the plates. This also results in greater efficiency when both discharging and recharging, providing longer life than conventional batteries and also greater electrical performance for the car.
Enhanced Flooded Battery, known as EFB or improved conventional batteries, are very recommended batteries for cars that have the start-stop system.
Some automakers have bet on this technology in their projects because it has a lower cost and electrical results similar to that of the AGM battery. But it is always advisable to consult the vehicle manual for correct application.
The EFB battery is the innovation of conventional batteries themselves; the EFB is mostly used in vehicles that require very light loads, such as those embarked with the start-stop system, which needs to make many starts along the way.
What is the start stop system?
The start-stop system is responsible for turning off the car engine automatically when it stops and for turning it back on automatically when the driver wants to move the vehicle.
Among the main objectives of the system are: to reduce CO2 emissions and reduce fuel consumption.
Now that you’ve learned what a sealed battery is, you’ll have no doubts about your next battery purchase, right? Always read our content and stay well informed.
