Furthermore, the VRLA design opens applications for lead-acid batteries where acid stratification had been an obstacle for the vented design.

What is a valve regulated battery?

The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market shortly after World War II and largely replaced lead-acid batteries in portable applications at that time.

What are the disadvantages of valve regulated batteries?

Disadvantages of valve-regulated batteries The major complication with the use of VRB tech nology is that very accurate control must be placed on the charging regime.

What is a valve-regulated lead-acid (VRLA) battery?

This version - the valve-regulated lead-acid (VRLA) battery - requires no replenishment of the water content of the electrolyte solution, does not spill liquids, and can be used in any desired orientation.

What does a lead acid battery do?

Lead–acid batteries are employed in a wide variety of different tasks, each with its own distinctive duty cycle. In internal-combustion engine vehicles, the battery provides a quick pulse of high-current for starting and a lower, sustained current for other purposes; the battery remains at a high state-of-charge for most of the time.

Can a VRLA battery be overcharged?

In Section 3.1, it has been shown as an advantage of VRLA batteries that overcharging is not required for mixing of the electrolyte. Nevertheless, in applications where the battery is cycled, a certain overcharge is usually applied even in the charging schedules of VRLA batteries for “equalizing”.
