The Advantages of a VRLA AGM Deep Loop Battery

VRLA AGM Deep Loop

VRLA batteries have two classes, AGM and Gel. Both classes have several advantages, including enhanced cycle life, capacity, and vibration resistance. These differences have prompted the development of different types of VRLA batteries. Learn more about these two types of batteries and the advantages they offer in your home or business.

Vibration resistance

There are two main types of VRLA batteries: Gel Cell and Absorbed Glass Mat. Both contain an immobile jelly-like electrolyte made from sulfuric acid mixed with fumed silica, a thickening agent. Gel Cell VRLA batteries are primarily used in electric wheelchairs and medical mobility systems. Other common applications for Gel Cell VRLA batteries are RV deep cycle batteries and trolling motor batteries.

VRLA batteries are designed to work in all orientations because of their sealed design. They use an immobilized electrolyte to prevent the plates from shedding during deep discharge. These batteries are ideal for renewable energy applications, where battery maintenance can be a huge hassle. AGM batteries are more commonly available and have numerous advantages. AGM deep-cycle marine batteries are available from many suppliers. They have low maintenance costs and are spill-proof. However, they are less cost-efficient than traditional flooded cell batteries.

AGM and Gel Cell VRLA batteries can be easily mounted and are maintenance-free. These batteries also do not need expensive ventilation equipment. Both types are widely used in off-grid power systems and large portable electrical devices. They have similar properties to lithium ion batteries and are generally less expensive.

Both types of VRLA batteries have a one-way valve to prevent overcharging and overheating. While this reduces the possibility of gas generation, a VRLA battery can still lose water if it overcharges. The one-way valve controls the pressure inside the battery and helps to prevent leakage and gas recombination.

Another important feature of VRLA batteries is that they are spill-proof. Because they are non-spillable, VRLA batteries can be installed in any orientation. Additionally, they do not spill electrolyte, so they are perfect for standby and UPS applications.

Increased cycle life

During the mid-1990s, consumers were still asking questions about the reliability of VRLA cells. They were finding that these cells drifted away from their average potential during long-term float charge operation. In addition, they were finding that they were limited in capacity because of a strong voltage scattering effect in the block electrodes. These defects, coupled with an increase in internal resistance, resulted in the development of a new failure mode that was named intrinsic failure.

VRLA and AGM batteries have been widely adopted for stationary applications, but their premature failure rate was high, typically within two to three years. The most common causes were cell drying and grid and busbar corrosion. To address these issues, changes in the alloy composition were introduced, including addressing the presence of residual elements in all cell components. These changes improved deep discharge cyclability. The two types are similar in performance, and they can be used in different roles.

An added carbon material, such as SSA or RGO, can improve the performance of VRLA batteries. These materials have a small pore size, which can increase the battery’s charge acceptance. Further, their mesoporous structure provides channels for the acid electrolyte. This can increase the VRLA battery’s cycle life.

Graphene is another important additive that can significantly improve the performance of VRLA batteries. Graphene improves the charge acceptance ratio of the battery and enhances the cycle life. It also has a positive effect on low temperature performance. It can also help improve the battery’s performance in large-current discharges.

Another advantage of VRLA AGM Deep Loop batteries is their reduced maintenance costs. As compared to flooded cells, these batteries offer greater resistance to shock. They are also more vibration resistant.

Longer life

If you are looking for a reliable, long-lasting battery, a VRLA AGM Deep Loop is an excellent choice. These batteries offer a life span of between three and five years. In rack mounted batter addition, their internal resistance is relatively low. This makes them ideal for high-current discharge applications.

AGM batteries use a gel-like substance to transfer the electrolyte between rack mounted batter the battery plates. This design reduces evaporation and gassing, and it helps the battery survive harsh conditions. Also, unlike flooded batteries, AGM batteries are designed to withstand vibration and shock much better than conventional batteries.

The efficiency of lead-acid and alkaline batteries is typically around 85-95%, and true deep cycle AGM batteries reach 98% efficiency under ideal conditions. However, the average consumer should account for at least a 10% to 20% loss of power when sizing their battery.

Compared to SLA batteries, AGM batteries are maintenance-free and feature an ABSORPTED GLASS MATS separator between the plates. This separator wicks the electrolyte solution between the plates to maximize the surface area where the electrolyte can reach the plates. This makes it possible to use a smaller volume of electrolyte in the same battery.

AGM batteries are a great choice for many applications. They typically have a lifespan of three to five years when properly maintained. Their long life is also a bonus if you need to use the battery outdoors for extended periods of time. These batteries can also be used in low-temperature conditions.

Increased capacity

Despite their similar capacities, AGM and VRLA batteries are not the same. These batteries are made with different constructions and are best used for specific applications. To maximize power density, high-rate performance, and life, it is important to use the right type of battery. VRLA batteries are often used in telecom applications and large portable electrical devices.

VRLA batteries are designed to provide high-power capacity by storing electricity in a sealed form. Deep-cycle service can reduce the risk of electrolyte spillage and evaporation. They are also more resistant to shock. And while these batteries are similar to other wet-sealed batteries, they do have certain advantages. One of these is that they contain calcium in the lead plates.

Another characteristic of AGM batteries is that they do not need to be discharged. In addition, they have low gassing characteristics, so they do not require a watering service. This allows them to perform better than flooded batteries in high-maintenance applications. They are also more cost-efficient.

AGM batteries are compatible with standard chargers. They use the same charging voltages. They do not heat up under heavy charge currents. Moreover, they do not have discharge current limits. Unlike other batteries, AGM batteries are low-self-discharge, which means that they can be left unused for long periods without causing any problems.

Higher rate of discharge

VRLA AGM batteries are characterized by their high-rate discharge capacity and long life. The AGM technology features thin glass fibers to maximize surface area. The AGM technology also allows for an oxygen recombination cycle. The DCS version of the AGM is specially designed for deep-cycle service. It contains an alloy grid and a positive paste formula.

The lead-antimony alloy used in VRLA AGM batteries is not suitable for battery straps. The antimony in these batteries reacts with water and causes recombination on the negative strap. This causes the negative lug to experience corrosion. This ultimately leads to the separation of the negative lug.

Deep-cycle VRLA batteries were developed in the late 1960s. These batteries are ideal for extended periods of storage and are designed to eliminate the need for adding water. The deep-cycle technology involves a special design that allows the oxygen generated at the positive plate to migrate to the negative plate. The oxygen in the battery is reduced to water, but this process is not 100% efficient. This is why the VRLA battery has a pressure vent.

In addition, the AGM and VRLA battery series feature low internal resistance and are suitable for high-rate applications. However, their different characteristics make it important to choose the right type of battery for your application. The right choice will ensure optimum power density, high rate performance, and longevity.

VRLA AGM deep cycle batteries have a higher self-discharge rate. When you fully charge them, it is best to charge them to at least 50%. Discharging below half-charge can shorten their lifespan.
