Is the OPzV Battery Solid State?

The OPzV battery is not considered a solid-state battery. Here’s an overview to clarify the differences and characteristics of the OPzV battery.

Characteristics of OPzV Batteries

  1. Type:
    • OPzV batteries are valve-regulated lead-acid (VRLA) batteries that use a gel electrolyte.
  2. Electrolyte:
    • They contain a gelified sulfuric acid electrolyte, which is immobilized using silica gel. This gel prevents the electrolyte from spilling and allows the battery to operate in various orientations.
  3. Construction:
    • OPzV batteries use tubular plate technology, which provides a long cycle life and excellent deep discharge performance.
    • They are sealed and maintenance-free, meaning they do not require regular topping up with water.
  4. Applications:
    • Commonly used in renewable energy systems, telecommunications, backup power systems, and other applications requiring reliable, long-life energy storage.

Solid-State Batteries

  1. Type:
    • Solid-state batteries use a solid electrolyte instead of the liquid or gel electrolyte found in traditional batteries.
  2. Electrolyte:
    • They feature solid electrolytes, which can be made of ceramics, polymers, or other solid materials.
  3. Advantages:
    • Higher energy density.
    • Improved safety due to the lack of flammable liquid electrolytes.
    • Potential for longer lifespan and better performance at various temperatures.


  • Electrolyte:
    • OPzV: Gelified sulfuric acid (liquid immobilized in gel form).
    • Solid-State: Solid electrolyte (ceramic, polymer, etc.).
  • Construction:
    • OPzV: Tubular plate lead-acid with gel electrolyte, sealed VRLA design.
    • Solid-State: Solid electrolyte with potentially different electrode materials and designs.
  • Applications:
    • OPzV: Renewable energy, telecommunications, backup power.
    • Solid-State: Emerging applications in electric vehicles, portable electronics, and more advanced energy storage solutions.

In summary, OPzV batteries are advanced VRLA gel batteries with significant advantages in certain applications, but they are not solid-state batteries. Solid-state batteries represent a different technology with distinct characteristics and potential benefits.
