Why Front Terminal battery?
Traditionally 2v AGM VRLA battery has been used in telecom tower applications. The rapid increase in density of towers in thickly populated areas have led to the need for batteries with a smaller capacity & a smaller footprint to be housed inside the Base Station Cabinet itself. This reduced the need for a separate space & a separate cabinet for housing the large 2v battery. These stringent requirements led us to develop the Dunia Front Terminal battery which is a sleek compact & yet very robust deep cycle battery which can perform in high-temperature conditions

Being housed inside the crowded Base Station Cabinet, the access to the battery terminals of traditional 12v batteries with terminals on opposite sides, could not suffice the job. Battery manufacturers redesigned the terminals which were shifted to the front enabling easy battery connections & ease of maintenance & voltage readings. This has become popularly known as Front terminal battery and is a true front access battery.

True Front Access Battery manufacturer in India - 12v 100Ah to 12v 200Ah

Microtex Dunia Front Terminal Battery are 12v valve-regulated VRLA batteries with high power-density having high-temperature (AGM) absorbent glass mat separators. Available in a wide range of 12v battery from 100Ah to 200Ah. AGM Front terminal Battery for the Standby Power & Telecom industry from Microtex are sealed maintenance-free battery and come with assured quality.

What is a VRLA Battery? Valve Regulated VRLA lead Acid or commonly called VRLA Battery are sealed maintenance-free. It is sealed for the life of the battery. Have no water loss, due to the gas recombination process. Water loss is eliminated making it a maintenance-free battery. The absorbent glass mat (AGM) design allows transport for the gas recombination of Oxygen inside the battery. As the gases are transported through the absorbent glass mat separator, it recombines hydrogen & oxygen, to form water which goes back into the chemical reaction to generate power on the next charge-discharge cycle.

These 12v Front Terminal battery are rechargeable lead-acid battery banks used for power backup as a battery bank with high rates of discharge typically used inside of cabinets in, Telecom, Data centres, and Standby applications. Microtex Sealed Lead Acid batteries, being a gas recombination valve regulated lead acid AGM VRLA battery, it is a completely sealed maintenance-free SMF battery. The internal resistance is measured for each and every cell to ensure high consistency & reliability. High-rate discharge test is performed for each cell to ensure battery integrity. Voltage is regulated by the correct and balanced active materials proportions, ensuring high cycle life performance.

What is the difference between AGM and standard batteries?

VRLA battery meaning – it is simply a lead-acid battery in which the electrolyte has been immobilised in order to recombine hydrogen and oxygen. It has a sealed construction with pressure release valves to prevent gases from escaping, It is this which gives it its name. Because the electrolyte is no longer in a fluid state, due to either being mixed with silica powder to form a gel or absorbed into a finely textured glass mat, the gases produced are not free to form bubbles and rise to the surface of the electrolyte. 

Instead, they are trapped in the immobilised matrix and forced to travel to the opposite poles by the pressure gradient produced when on charge. In a free liquid, this would be impossible.

What is a VRLA battery?

 In a VRLA battery, the oxygen produced at the positive migrates to the negative where it is reduced to reform water.
In a standard flooded battery, there is a vent hole provided to add DM water to compensate for the normal losses in the battery under operation. Modern flooded batteries, like Microtex with good designs will not require water topping up for over 18 months

Why AGM batteries are better?

Because the VRLA AGM batteries retain and recombine the oxygen and hydrogen produced when charging, they do not need to be topped up with water over their guaranteed life. Added to this benefit of lack of maintenance is the ability to seal the battery, which prevents the release of combustible hydrogen. Other benefits which derive from the immobilisation of the electrolyte include non-spillage or leaking of corrosive acid which makes handling and transport safer. These attributes are clear advantages to businesses and consumers, making this technology far more user friendly than flooded lead-acid batteries. 

In commercial operation it can mean cost reductions by removing gas extraction equipment and can make better use of available storage space due to its ability to operate on its side, giving more flexible installation options.
With these advantages, it is hardly surprising that the VRLA battery is regarded as the most versatile and user-friendly member of the lead-acid family. This is reflected in the off-grid power market applications in which this battery technology has significant market share.

Can I replace AGM battery with lead acid?

This is a common question we hear from our customers. When they say lead acid battery they mean flooded lead-acid batteries. To be fair, we would say that the answer lies in the application & customer needs. An AGM battery would be ideal in remote places where the possibility of maintenance is remote like in a hill station site of a telecom tower. However, if it is your home that requires the choice, it is better to go in for a flooded tubular battery, which offers better deep cycle recovery.

Do AGM batteries need to be vented?

AGM batteries though sealed have a safety valve-regulated vent to release the excess pressures that build up inside the sealed battery. If this vent-valve was absent the pressures could blow up the battery. Hence it is a very critical component of the AGM battery & must operate with precision over the batteries service life.

Are AGM Batteries better?

Indeed they offer the luxury of not having to top-up the battery every so often! This comes at a cost as the AGM batteries are by design made up of flat plate electrodes. The tubular battery requires topping-up with water, but have a longer life than AGM batteries. AGM batteries have several advantages in terms of savings in maintenance costs. It is really the users’ decision to outweigh these benefits & trade-off the costs.
