VRLA stands for Valve Regulated Lead-Acid. Which of the following is the correct full form?

Explanation:
VRLA refers to a sealed lead-acid battery that uses a valve to regulate internal gas pressure, making it maintenance-free and able to recombine gases inside. The established terminology is Valve Regulated Lead-Acid, which correctly describes the chemistry (lead-acid) and the safety feature (valve-regulated). The other options don’t fit because they either change the chemistry (lead alloy), imply a vacuum system, or reorder the words in a nonstandard way. So the correct full form is Valve Regulated Lead-Acid.
