Choose sealed or flooded deliberately
NPFG reduces routine electrolyte access; OPzS requires ventilation, electrolyte and maintenance planning.
Stationary GEL and flooded tubular routes
OPzV / OPzS Tubular Battery
Two long-duration stationary choices that must not be treated as the same product: sealed front-terminal GEL NPFG blocks and serviceable flooded OPzS tubular cells.

Product range
Models, ratings and practical differences
The supplied catalogue page does not show a separate OPzV model table; it shows NPFG front-terminal GEL 12V models from 55Ah to 155Ah and OPzS flooded tubular 2V cells from 150Ah to 1000Ah. OPzS is listed with a 15-year floating design-life statement and more than 1,000 deep cycles. Because OPzS is flooded, electrolyte, ventilation and maintenance planning differ materially from sealed GEL products.
Model comparison
Compare the ratings that affect your installation.
These figures come from the manufacturer catalogue. Ask for the current datasheet before final approval or purchase.

How to choose
Start with the load, charger and available space.
Send the information you already have. We can narrow the model list and point out what still needs to be checked.
Size the 2V string
Define DC voltage, cell count, autonomy, end voltage, redundancy and rack footprint.
Plan the battery room
Check floor loading, spill control, ventilation, inter-cell links, access and lifting before quotation.
Typical applications
Where buyers use this battery family
Tell us about the equipment and duty cycle. We will help check whether this series is a practical fit.
Utility and substation backup
Long-duration stationary DC systems with defined inspection and maintenance practice.
Renewable-energy banks
Projects with repeated cycling, autonomy and a battery room designed for the chosen construction.
Telecom and infrastructure
NPFG may fit front-access cabinets; OPzS may fit larger maintained stationary rooms.

Product FAQ
Questions buyers ask before ordering
We will confirm current availability, documents and commercial terms for the exact model you select.
Does the supplied catalogue include an OPzV model table?+
No separate OPzV table is identifiable in the supplied pages. The published comparison therefore uses NPFG sealed GEL and OPzS flooded tubular models and requires a separate current OPzV document for an OPzV quotation.
What is the key difference between NPFG and OPzS?+
NPFG is sealed front-terminal GEL in 12V blocks; OPzS is a flooded tubular 2V cell requiring a maintained installation.
What OPzS capacities are listed?+
The catalogue lists 2V models from 150Ah through 1000Ah.
What life statements are shown for OPzS?+
The catalogue states 15 years design life in floating condition and more than 1,000 deep cycles.
Why are dry and filled weights both relevant?+
Flooded OPzS cells add electrolyte weight at installation, which affects handling, rack and floor loading.
