    FAQs about Valve regulated lead acid battery cycle times

    How does a valve regulated lead-acid battery work?

    The valve-regulated lead–acid (VRLA) battery is designed to operate by means of an internal oxygen cycle (or oxygen-recombination cycle), where oxygen is evolved during the latter stages of charging and during overcharging of the positive electrode.
