Description
The tubular positive plate holds the active mass in a gauntlet, so it withstands deep discharges without shedding. The 2 V cells give over 2000 cycles at 80% DoD, the 12 V monoblocks 1400 cycles at the same depth. The cell range runs from 2OPzS100 to 24OPzS3000, so a battery for a large backup is assembled from separate jars rather than by paralleling strings. The battery is serviceable, the electrolyte is liquid and gas is released during charging, so periodic topping up with distilled water and room ventilation are required. The operating range of –15…+55 °C suits unheated substation rooms and solar power plant containers.
How to choose
The main decision concerns the format. The 2 V cells are more cost-effective for large capacities and give more cycles, while 12 V monoblocks are simpler to install in small systems. If the room cannot be equipped with ventilation and access for topping up, it is better to take sealed VRLA batteries, for example cycling AGM LPC of 3.5–150 Ah. For forklifts and traction applications there are separate PzB (BS) cells.

FAQ
How many cycles does OPzS withstand at 80% DoD?
The 2 V cells over 2000 cycles, the 12 V monoblocks 1400 cycles at a depth of discharge of 80% DoD.
What is the maximum capacity of OPzS cells?
The range ends with the 24OPzS3000 cell of 3000 Ah; the smallest cell, 2OPzS100, has 100 Ah.
Do flooded OPzS batteries need maintenance?
Yes, the electrolyte is liquid. The level must be checked, distilled water topped up and the battery room ventilated.
In what temperature range do OPzS batteries operate?
The operating range is –15…+55 °C. A service life of up to 20 years is reached at a moderate room temperature.
