The most essential difference between OPzV and OPzS batteries lies in the electrolyte medium and the way it is immobilized within the battery.
- OPzV Batteries (Tubular Gel Batteries): OPzV batteries use a gel electrolyte, which is a thick, jelly-like substance that immobilizes the electrolyte within the battery. This gel electrolyte is contained in tubular plates, which are made of a lead alloy with a small amount of antimony. The gel electrolyte and tubular plates provide excellent resistance to vibration and mechanical stress, making OPzV batteries suitable for applications where the battery may be subjected to rough handling or high levels of vibration.
- OPzS Batteries (Flooded Tubular Batteries): OPzS batteries use a liquid electrolyte, which is a solution of sulfuric acid and water. This liquid electrolyte is contained in tubular plates, which are made of a lead alloy with a small amount of antimony. The liquid electrolyte and tubular plates provide excellent resistance to corrosion and high temperatures, making OPzS batteries suitable for applications where the battery may be subjected to harsh environmental conditions.
In summary, the main difference between OPzV and OPzS batteries lies in the electrolyte medium and the way it is immobilized within the battery. OPzV batteries use a gel electrolyte, while OPzS batteries use a liquid electrolyte. Both types of batteries use tubular plates, but the gel electrolyte in OPzV batteries provides better resistance to vibration and mechanical stress, while the liquid electrolyte in OPzS batteries provides better resistance to corrosion and high temperatures.
