VRLA batteries are predominately used for UPS. These batteries are designed for remarkable performance, supplied in factory charged condition with modules in ready to use state. Centielindo presently has the following two specific technologies:

Absorptive Glass Mat (AGM) VRLA where the electrolyte in the cell is locked in a fiber glass mat between the plates. This valve regulated lead acid technology is low maintenance because it never needs watering.

Turbular Gel VRLA batteries to cater to the Telecom market. The electrolyte is fixed in a gel suspension between the plates. This valve regulated lead acid technology is low maintenance because it never needs watering.

VLA Flooded lead acid batteries have cells with liquid electrolyte and are available in flat and tubular plate constructions with a wide variety of plate sizes.

Vented Lead Acid batteries are most commonly used in central office applications or sites with a high capacity demand and a large allowable space for the battery system. 300-4000 Ah per battery equating up to 8.000 Watts per cell.

Flooded cells provide a much longer lifespan than their equivalent VRLA batteries but also require more maintenance than their VRLA counterparts.
