What is difference between OPzV and OPzS battery?


1.OPzV and OPzS batteries both are very popular stationary batteries

OPzV battery and OPzS batteries are very popular stationary batteries, developed at the end of 2005. OPzV and OPzS batteries are high-end products, specially developed for applications that require frequent deep cycling. This is an energy-saving solution for energy storage. Even in remote installations that require long-term discharge and excellent charging performance, it can provide significant advantages in terms of single-cycle cost, the highest level of reliability and performance.

 2.What do OPzS and OPzv battery stand for ? 

 OPzS stands for : O = Ortsfest (stationary) Pz = PanZerplatte (tubular plate) S = Flüssig (flooded)

 OPZV stands for :O =Ortsfest (stationary) ,PZ=PanZerplatte (tubular plate) V-Verschlossen (Sealed)

3.What are the Common features of OPzS and OPzV ?

3.1 OPzV and OPzS batteries can offer longer service life 

Both OPzV and OPzS are lead-acid batteries. They are tubular plate batteries. Their positive plate is a tubular plate, which increases the surface area of the positive plate. The capacity of the tubular battery is 20% more than that of a flat battery of comparable size and weight. And the capacitance of the tubular plate is larger than that of a plate of similar size and weight. Compared with a flat battery, the service life of the tubular battery can be extended by 30% after eliminating the positive electrode falling off. For stationary applications, perhaps the most important thing is that the tubular positive grid does not require horizontal rods, which actually eliminates the growth of the positive plate, thereby eliminating the leakage of the rear seal and the cracking of the can. As a result, in the applications requiring long service life, the tubular plate battery can provide the best and most reliable power.

3.2 The application areas of OPzV and OPzS battery are the same.

OPzV and OPzS battery voltage is usually 2V, users can connect the batteries in series to generate higher voltage.Their application areas are the same. They can be used in telecommunication equipment, electronic instruments, fire alarm devices, security device, UPS power supply, solar power system, wind power system and so on.

4.What is difference between OPzV and OPzS battery?

OPzV is the tubular GEL battery. And OPzS is the tubular flooded battery. OPzS is a flooded cell, meaning the electrolyte (generally sulfuric acid) is in liquid form inside the cell. And the electrolyte of OPzV within the battery is in gel form which allows for recombining the electrolyte back into water. OPzV battery is sealed battery and user don’t need to maintain the battery. But OPzS battery is not sealed. Users occasionally need to add distilled water to the top of the battery to maintain the normal use of the battery.

5.How to choose OPzV and OPzS battery?

When you are confuse how to choose solar battery(battery for your solar system), VELA solar battery is your good choice. VELA can produce both OPzV and OPzS batteries. In terms of performance, both OPzS and OPzV have excellent deep cycle characteristics. When the discharge depth is 80%, the cycle times of OPzS batteries can reach 2300 times. OPzV battery cycles up to 2100 times. In terms of price, OPzS is a bit cheaper than OPzV. But the OPzS battery need to be maintained sometimes and the OPzV battery is no need to maintain. If you can maintain the battery occasionally and add a little distilled water to the battery, you can choose OPzS battery. If you don't want to maintain the battery, OPzV will be more suitable for you.
