Vrla Batteries
Advantages and Disadvantages of AGM VRLA Battery
Absorbed glass mat (AGM) Battery is a class of VRLA battery in which the electrolyte is held on the glass mat separator by way of capillary action. The AGM battery is different from other lead-acid batteries because it uses a glass mat separator to maintain its position in electrolytes. These rugs can be used for the AGM with the highest frequency of acid build up there and never paid a drop. There, in 1980 by Concorde Aircraft Battery was developed was their intention, a warm climate, vibration-proof chemical alternative to expensive batteries of their current technology used to build fighter planes. Today, the general assembly is used in many motorcycles and cars. They are also often in remote sensing and cold environments because of their lack of electrolytes have never attack or use crack.
Advantages of AGM VRLA Battery
All AGM batteries boast some significant performance enhancement over traditional flooded lead acid cells:
•AGM construction allows purer lead in the plates as each plate no longer needs to support its own weight based on the sandwich construction with AGM matting. Traditional cells must support their own weight in the bath of acid.
•AGM Batteries are un-spillable, keeping lead and acid out of the environment.
•AGM Batteries have high specific power or Power Density, holding more roughly 1.5x the AH capacity as flooded batteries based on purer lead.
•AGM Batteries have very low internal resistance allowing them to be charged and discharged quite rapidly without creating heat based on construction and pure lead.
•AGM Batteries are maintenance free, never requiring a watering over the life of the battery.
•AGM Batteries will not corrode their surroundings as the acid is encapsulated in the matting.
•AGM Batteries will not freeze and crack, operating well below 0°F or C.
•AGM Batteries can be UL, DOT, CE, Coast Guard, and Mil-Spec approved to isolate HAZ-MAT.
•AGM Batteries are exceptionally vibration resistant based on the sandwich construction.
Disadvantages of AGM VRLA Battery
•Cost. AGM automobile batteries for example, are typically about twice the price of flooded-cell batteries in a given BCI size group.
•AGM Batteries boast up to a 10 year lifespan, but must be sized to discharged less deeply than the traditional flooded batteries.
•AGM Battery depth of discharge for optimal performance 50% Flooded Battery depth of discharge for optimal performance 80%
•AGM Batteries do not tolerate overcharging. Overcharging burns electrolyte, which is unable to be replaced, leading to premature failure.
For marine applications, there is a clear cut winner between these two technologies of lead acid battery. AGM Battery will always beat a GEL battery for marine applications. Simply put, any AGM battery is stronger, lasts longer, and is safer than any gel battery on the market. VRLA battery doesn't require any maintenance which is very different from the standard lead acid battery that always needs to add distilled water.
