Flooded Classic® PDQ / PWQ

GNB Flooded Classic® PDQ / PWQ 4-volt and 8-volt multi-cell batteries are industry-proven solutions for uninterruptible power supply (UPS) and utility applications.

  • Nominal Capacity Range: 1,680 – 4,217 watts per cell (WPC)
  • Design Life: 20 years @ 77°F / 25°C
  • Float Voltage: 2.23 VPC – 2.33 VPC (1.250 specific gravity)
  • Float Voltage: 2.17 VPC – 2.25 VPC (1.215 specific gravity)
  • Flat-plate flooded design with patented lead-calcium-tin-silver positive-plate alloy reduces grid corrosion
  • PWQ model features wrapped separator design to minimize positive-plate shedding effects
  • Fully recyclable

Features & Benefits

uninterruptible power supply
  1. High-Quality Premium Plastics

    • Heavy-duty container (ABS) and (SAN) cover plastics
    • Flame-retardant polycarbonate option (UL 94 V-0 / 28% L.O.I.)
    • Flame-retardant PVC option (UL 94 V-0 / 32% L.O.I. in 2-cell containers)

  2. Superior Terminal Post Design

    • Lead-plated posts with copper insert provide low resistance and facilitate excellent high rate performance
    • Dual seal (O-ring and flat-gasket) design to help prevent acid creep into the post area

  3. Ease of Safety and Maintenance

    • Electrolyte level lines on all container faces.
    • Combination flash arrester/fill funnel for each cell.
    • Electrolyte withdrawal sampling tubes permit accurate specific gravity readings.
