Description
The liquid electrolyte and vented design need water to be added periodically, but water consumption in this series is reduced, so the intervals between servicing are longer. To order, the cells are fitted with flame-arresting vent plugs, which do not let a flame into the battery from a nearby spark. Lead purity is 99.99%, which reduces self-discharge and gas evolution. The tubular plates hold the active mass in gauntlets and, together with the reserve of liquid electrolyte, give a long service life in float mode. The operating temperature range of –20…+55 °C removes the requirement to heat the battery room, although in winter the capacity will be lower. The range consists of 2 V cells and 6 and 12 V monoblocs. The battery room is equipped with ventilation to remove the hydrogen released during charging.
How to choose
Selection of OPzS starts with the capacity for the required autonomy time and the bus voltage, which is built by connecting 2 V cells or 6 and 12 V monoblocs in series. If the room has no ventilation or maintenance staff, it is better to take the sealed gel OPzV of 54–3718 Ah. For solar power plants with daily cycling the related RES OPzS series of 89–4923 Ah with a life of 2800 cycles at 50% DoD is suitable. Flame-arresting vent plugs are ordered at once if increased fire safety requirements are placed on the battery room.

FAQ
How often should water be added to OPzS batteries?
The interval depends on the float mode and temperature, but in this series water consumption is reduced. The electrolyte level is checked during scheduled maintenance and distilled water is added.
Why are flame-arresting vent plugs used in flooded batteries?
They prevent a flame from an external spark from getting inside the cell, where there is hydrogen. For OPzS such plugs are supplied as an option.
What is the service life of OPzS stationary batteries?
Up to 20 years is declared. This life is reached with the correct float voltage, timely water topping up and a moderate temperature in the battery room.
How does OPzS differ from RES OPzS?
Both series are flooded with tubular plates, but the OPzS is designed for standby power with rare discharges. The RES OPzS is intended for daily cycling in systems on renewable sources and has a life of 2800 cycles at 50% DoD.
In what range of capacities are OPzS batteries made?
The range covers 64–3671 Ah in 2 V cells and 6 and 12 V monoblocs.
