Tubular Gel Battery manufacturers in India
2v 100Ah to 2v 3000Ah

2v OPzV batteries in ABS containers are designed for deep discharge and float long-duration applications in the Solar off-grid backup, Offshore Oil rigsTelecommunication & Power Generation industries. Our OPzV cells are manufactured using the best industry techniques, extensive testing, and highest quality components. The ABS plastic containers maintain their rigid properties at a wide range of temperatures from −20 to 55 °C (−4 to 131 °F). 

Tubular gel (or T Gel) OPzV batteries have precision German vent valves and no opening for water levels to check. Being a sealed unit, there is no risk of acid spillage. This battery can be installed in a horizontal or vertical position. Recharging is performed much more efficiently due to the special design of the active materials for faster charge acceptance. Gelled electrolyte ensures no stratification of acid & failure due to Partial State of Charge (PSoC)

What does OPzV mean?

On an interesting note… OPzV Definition is derived from German words and stands for  O – Ortsfest (in German means Stationary) Pz – PanZerPlate means Tubular plate (for sturdy and robust) V – Stands for Verschlossen or Closed

What is OPzV Battery?

OPzV batteries are deep cycle batteries and generally refer to Sealed Maintenance Free Tubular Gel lead Acid Batteries in ABS containers. These batteries have a cell voltage of  2 volts and are connected together to obtain required voltages, usually used as a backup source in, Solar Battery applications, Power Generating Stations & Substation, Oil & Gas, Nuclear, Hydro & Thermal Power Generation Facilities, and Standby applications. The electrolyte is in gelled form and the battery does not leak.

What are 2v OPzV batteries? OPzV battery meaning

There are two principal methods for acid immobilisation:

  • the other, adding a fine silica powder to make a gel as in Gel Battery

Both methods, although very different, achieve the goal of immobilisation. They also provide the added benefit of recombining the gases released on charge to reform water, thereby removing the need for the water-addition maintenance procedures mentioned earlier for flooded lead-acid batteries. 

Out of these two methods, the use of silica-gelled electrolyte is universally recognised as the best solution for deep discharge gel cell battery designs. There are two main reasons for this: the first is that the use of gelled electrolyte allows a tubular positive plate to be used, which is recognised as providing the best deep cycle properties for lead-acid batteries. The second reason is that the stratification of acid associated with deep discharges and limited-voltage recharging without gassing is avoided. These are significant advantages if you have deep cycle requirements as in solar battery applications.

OPzV Battery technology. What is gel battery technology?

So just how do this combination of tubular plate and GEL electrolyte work? To understand we have to look at several elements which contribute to the battery’s properties, these are:

An electrolyte which is immobilized as a GEL to ensure non-spillage and also to enable the transportation of hydrogen and oxygen released on charging (which is held inside the battery under pressure) to be recombined to form water. The benefit of immobilization extends further, it prevents the creation of strata of acid with different densities within the cells, called Acid Stratification. 

In flooded batteries and sometimes AGM VRLA designs, denser gravity acid produced at the plates during charge can drop to the bottom of the cell leaving the weaker gravity acid at the top. Batteries in this condition suffer early failure from battery sulfation, premature capacity loss (PCL) and grid corrosion. Microtex have a Tubular gel battery plant imported from Germany and use high-grade imported fumed silica to give uncompromising life and performance to their Tgel cells.

OPzV vs OPzS Battery

OPzV Batteries are sealed maintenance-free batteries working on the VRLA oxygen recombination principle & requires no water topping-up. The vent is sealed with a valve-regulated plug which should not be opened. OPzS batteries are similar in basic construction using tubular plates however the electrolyte is flooded. The cell container has a vent for topping-up water lost during normal battery operations.

What is a tubular gel battery?

Tubular gel battery There are distinct advantages of lead-acid battery technology compared to lithium-ion battery & other electrochemical systems. Affordability, reliability, recyclability and safety are key issues in choosing the right battery for a particular application and lead-acid batteries will score highly in these categories. There is, however, a drawback when using conventional flooded lead-acid
