Renewable energy sources only generate power when the sun shines or the wind blows. Optimizing green energy production into the daily grid cycle requires bulk energy storage. New load-leveling installations are accompanying renewable energy plants across the globe. Today, maintenance-free valve-regulated lead-acid (VRLA) batteries with premium H&V separators are the leading electro-chemical storage solution worldwide.

  • H&V’s separators are installed in multiple large energy storage projects around the world.
  • Our battery separators feature more than 94% porosity for maximum acid storage.
  • Applications

    H&V’s separators have proven reliability in all grid storage applications.

    Features include:

    • Cycling optimization
    • Reserve capacity optimization
    • High-porosity for maximum electrolyte volume
    • Compression maintenance (recovery)
    • Chemical purity and consistency
    • Electrolyte stratification resistance
    • High-rate discharge performance
    • Thickness and basis-weight control
    • Electrolyte–filling efficiency
    • Wrapping/stacking efficiency
    • Assembly defect reduction (rips, splits, tears, and punctures)
    • Paste imperfection protection (paste lumps, spurs, etc.)

    H&V’s EnergyGuard® separators are high-strength and optimized for deep discharge applications. EnergyGuard separators use a small portion of stable thermoplastic fibers to greatly improve tensile and puncture strength. An all-glass alternative, our BGO and BGCB separators, are a popular choice for VRLA batteries designed to over long life.
