Stationary lead-acid battery systems

Reliable stationary battery systems for all emergency power supply applications

Ensuring functionality through regular maintenance

Stationary battery systems play a crucial role in emergency power supply, as they are reliable energy providers for UPS and BSV systems, emergency lighting, signalling and safety equipment, DC power supply systems, diesel starting systems and much more. Since all these applications are safety-relevant systems, you should not compromise on quality here. Therefore, you can rely on the stationary battery systems from Allgäu Batterie, which offer you maximum security of supply.

Why lead?

Everyone is talking about the lithium-ion battery. And rightly so, because the technology offers specific advantages that provide real added value in appropriate applications. Nevertheless, we rely on lead-acid batteries for many stationary applications such as UPS systems, emergency lighting systems and battery-based central power supplies. And there are good reasons for that:

  • Proven technology with long service life
  • High recycling rate
  • Optimal price-performance ratio

Types of stationary battery systems

For application areas in standby operation with capacitive discharges, such as UPS systems and fire alarm centers, we use sealed lead-acid batteries (OGiV, OPzV, AGM).

For cyclic and capacitive discharges we use closed batteries (OPzS, OGi). Nickel-cadmium (NiCd) batteries are also available for this purpose. Typical applications are BSV systems, starter batteries for diesel generators and emergency power generators, safety lighting systems and UPS systems with long bridging times or high discharge loads.

To choose the right technology, it is essential to have our experts evaluate the availability requirements of the application with the relevant operating parameters, the environmental conditions of the installation site and the legal requirements.

Project planning

A stationary battery system requires thorough project planning. For a proper battery room, all aspects of operational safety, such as statics, ventilation, acid protection, fire protection and labeling, must be planned and implemented in compliance with the standards. Our stationary battery systems meet the requirements of DIN EN IEC 62485-2.

Particular attention is also paid to electrotechnical safety, because often these are systems that fall within the scope of live work in accordance with DIN VDE 0105-100. From installation to commissioning and maintenance, we recommend that this be carried out exclusively by our qualified electricians with special AuS training.

Racks and cabinets

The installation situation is individual for each project. Depending on space conditions, statics and safety requirements, we define the appropriate solution. In addition to cabinets are most often used racks. Both are available in different versions.

  • Floor, tier and step construction
  • Earthquake-proof for regions with high seismic activity
  • Air conditioned for areas with high ambient temperature
  • Cabinets with drawers
  • Central degassing for the removal of the hydrogen gas
  • Special designs for special requirements, e.g. protection class IP65

Optional: VdS certified batteries

According to VdS Guideline 2102, only tested maintenance-free lead batteries may be used for hazard alarm systems. Certification is a prerequisite for using these batteries in security-related hazard detection systems such as burglar or fire alarm systems without losing insurance coverage. These batteries can be recognized by the approval number printed on them.

Service & Maintenance

Although the individual blocks are usually designed as a low-maintenance variant, the specifications of the legislator and the manufacturer must nevertheless be observed. Particular importance is given here to adequate ventilation, which ensures that no explosive atmosphere is formed.


Systems for emergency power supply require a permanent voltage source in order to reliably take over the supply in the event of a power failure. Stationary battery systems must therefore be maintained with the same care as the associated UPS systems.

If it becomes apparent during maintenance that full power is no longer being provided, our service technicians replace individual blocks or the entire battery system. By using an external load device and, if necessary, measuring the internal resistance, we obtain much more meaningful results than the method widely used on the market for determining condition by voltage alone, and can thus provide a sound basis for decisions on further measures.

Safety for man and machine: UPS system

In the event of faults in the power supply system, the safety of persons, electrical equipment and data can be extremely endangered. That’s why our uninterruptible power supply (UPS) systems step in as soon as the grid fails.
