6 FAQs about [Valve regulated lead acid batteries in parallel]
Why should lead-acid batteries be valve regulated?
Thus, the strong position of lead-acid batteries in this field will be improved by the valve-regulated design, and they will remain in widespread use in the future. 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 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 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 is a 'valve-regulated lead-acid' cell?
Moreover, acid is immobilized in the new design and this endows the cell with the additional advantages of being ‘spill-proof’ and able to operate in any orientation (upright, on its side, or even upside down). The change to the so-called ‘valve-regulated lead–acid’ (VRLA) technology has not, however, been accomplished without some difficulty.
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 lead-acid battery be sealed?
The unavoidable hydrogen evolution would cause a continuous increase of the internal pressure until the cell would be destroyed. For this reason, the lead-acid battery cannot be sealed, but has to have a valve that opens from time to time and allows the escape of hydrogen, even under normal operational conditions.
