The valve regulated spill-proof construction of valve-regulated lead-acid (VRLA) battery, commonly known as a sealed lead-acid or SLA battery allows trouble-free, safe operations in any position. There is no need for added external electrolytes as the gags generated during charging are recombined in a unique "oxygen cycle".
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.
