Purpose of a valve regulated Battery

Valve Regulated Lead Acid (VRLA) batteries are a specific type of lead-acid battery, designed to minimize maintenance requirements and prevent gassing and acid leakage. These batteries are sealed, except for a release valve that activates when the internal pressure exceeds a predefined limit. The main purpose of a VRLA battery is to offer efficient, safe, and long-lasting energy storage solutions by controlling the emission of gases, ensuring consistent water levels, and optimizing energy efficiency.

Introduction to Valve Regulated Batteries

Valve Regulated Batteries play a crucial role in various industrial and commercial applications due to their maintenance-free design and enhanced safety measures. Their sealed nature makes them preferable for environments where gas emission could be hazardous.

Design Parameters of VRLA Batteries

  • Voltage Range: Typically, VRLA batteries come in 2V, 6V, and 12V varieties.
  • Capacity Range: They are available with capacities from 1Ah to several thousand Ah, making them suitable for multiple storage needs.
  • Operating Temperature: Generally optimized to function between -20°C to 60°C.
  • Cycle Life: These batteries can withstand up to 1200 cycles at 30% depth of discharge.

Operation Mechanism

The core function of a VRLA battery is to regulate the recombination of gases. It strategically recombines hydrogen and oxygen within the battery to form water, minimizing water loss and obviating the need for periodic refilling. The valve regulates gas escape, ensuring safety and longevity.

Advantages of VRLA Batteries

  • Maintenance-Free Operation: No need for regular topping off with water.
  • Enhanced Safety: Sealed design mitigates risks of acid spillage.
  • Space Efficiency: Compact and available for installation in various orientations.
  • Long Service Life: Designed to offer extended durability with minimal degradation.

Common Applications
