General Info on "Pz" batteries:

(O)PzS (Flooded) and (O)PzV (Gel)  are both tubular lead acid batteries. They have a higher lead content and more surface are providing them a higher energy density and longer lifespan.

 

(O)PzS batteries are a form factor designed for traction systems, meant to be put in a pack and bolted together by their terminals. There are 3 main types, PzS, PzB and PzV.

PzS is the Standard DIN style form factor Lead-Acid battery.

PzB is the less common BS (British Standard) form factor Lead-Acid battery.

PzV is either Standard DIN or BS, but in a Gel-Cell chemistry.

 

PzS    means                                               Pz = PanZerplatte (tubular plate) S = Flüssig (flooded) "MOTIVE"
OPzS means  O = Ortsfest (STATIONARY) Pz = PanZerplatte (tubular plate) S = Flüssig (flooded)

 

OPzS are recommended for backup applications (UPS/telecom)/stationary and deep cycle applications, where the battery is actually spending the most part of its life in float operation. That means the electrolyte concentration will stay high for a very long time hence there is an increased chance of plate corrosion (that's why most Battery manufacturers will   choose a lower (1.24) electrolyte density).

 

 

"OPzS vs PzS" ...

Basically:

Same efficiency

Same chemistry

Same electrical characteristics

More electrolyte in OPzS (stationary)

PzS (motive) is designed "stronger" to handle the forces of motion

PzS are cheaper (mass production).
