The acronym VRLA stands for:

Valve Regulated Lead Acid is a sealed lead‑acid battery where the electrolyte is immobilized (in AGM or gel form) and a valve allows gas to escape or recombine back into water as pressure changes. This design keeps the battery maintenance-free because it doesn’t require water additions, and it avoids spills in normal use. The valve is there to vent only when pressure gets too high, such as during overcharging or faults. That’s why this option is the best fit. The other phrases don’t describe the standard battery construction: there isn’t a common term like Vacuum Regulated Lead Acid; Voltage Regulated refers to how a charging system manages voltage, not to the battery’s sealed design; and Ventilated Regulated Lead Acid would imply a vented, not sealed, design, which contradicts the purpose of VRLA.
