Product Overview
The Siemens 6AG1134-0GB00-4AY0 is a SIPLUS PS UPS1100 Battery Module designed to provide backup energy storage for Siemens SITOP DC uninterruptible power supply systems. It is based on the corresponding UPS1100 battery module architecture and uses maintenance-free, sealed lead-acid batteries.
The module provides a 24 V DC, 7 Ah energy-storage solution and is intended to work together with compatible Siemens DC UPS equipment. During normal operation, the battery module is charged by the connected UPS system. When the primary 24 V DC supply becomes unavailable or unstable, the stored energy can be used to maintain the connected DC load for the required backup period.
The SIPLUS version is designed for more demanding industrial environments. Its conformal-coated construction and specified environmental characteristics make it suitable for control cabinets and industrial installations where temperature, condensation, dust, chemical exposure, or other environmental stresses may be present.
The supplied product information is:

PLC / HMI / Network / Critical Loads
This allows critical automation equipment to remain operational for a defined period rather than shutting down immediately after loss of the primary power source.
Role in Industrial Control Systems
The battery module is particularly important in automation applications where an uncontrolled power interruption could cause:
- PLC shutdown
- Loss of machine data
- Communication interruption
- Unexpected machine stopping
- Loss of process information
- HMI shutdown
- Controller restart
- Production interruption
A DC UPS battery module can provide the stored energy required for controlled shutdown or temporary continued operation.
Typical critical loads may include:
- PLC CPUs
- Industrial Ethernet equipment
- HMI panels
- Remote I/O
- Control relays
- Instrumentation
- Monitoring equipment
- Industrial PCs
The exact backup duration depends on the connected load and the operating condition of the battery.
Typical Industrial Applications

- Conveyor systems
- Robotic cells
- Material handling systems
The UPS can keep critical control electronics operating during short power interruptions.
Process Automation
Typical applications include:
- Water treatment
- Chemical processing
- Pump control

- Process monitoring
- Industrial instrumentation
Maintaining power to control electronics can prevent uncontrolled process interruption.
Data and Communication Systems
The battery module can support DC UPS systems supplying:
- Industrial Ethernet switches
- Communication equipment
- Remote I/O
- Control gateways
- Monitoring devices
Maintaining network availability can be important during short-duration power disturbances.
Machine Shutdown Protection
A DC UPS can also be used to provide sufficient time for:
- Saving machine data
- Completing controlled shutdown procedures
- Storing PLC information
- Closing applications
- Maintaining alarms
- Protecting critical process information

This process helps identify whether a backup-power problem originates from the main supply, UPS, battery, protection device, wiring, or connected load.
Battery Life and Maintenance
Battery life depends strongly on:
- Operating temperature
- Charging conditions
- Discharge depth
- Discharge frequency
- Storage duration
- Ambient conditions
Typical energy-storage service life decreases as temperature rises.
For this type of sealed lead-acid energy storage, higher temperatures can significantly accelerate capacity loss and aging.
For example, the technical data indicates a typical point at which capacity falls to approximately 80% of original capacity of:
| Temperature | Typical Service Life |
|---|---|
| 20 °C | Approximately 4 years |
| 30 °C | Approximately 2 years |
| 40 °C | Approximately 1 year |
| 50 °C | Approximately 0.5 year |
These figures should be treated as typical values rather than guaranteed replacement intervals.
Preventive Maintenance
| Inspection Item | Recommended Check |
|---|---|
| Battery Housing | Inspect for swelling or damage |
| Battery Terminals | Check for corrosion |
| Wiring | Inspect insulation and connections |
| Fuse | Verify condition |
| Polarity | Confirm correct connection |
| Charging Voltage | Monitor periodically |
| Battery Temperature | Monitor cabinet conditions |
| UPS Diagnostics | Review alarms |
| Backup Time | Test periodically |
| Battery Age | Track installation date |
A battery can appear physically normal while its actual capacity has already degraded. Backup-time testing is therefore useful for critical systems.
Battery Storage Recommendations
If the battery module is stored before installation:
- Keep storage duration as short as practical.
- Store the battery fully charged.
- Maintain suitable storage temperature.
- Avoid prolonged high-temperature storage.
- Inspect battery condition before commissioning.
- Recharge according to the applicable maintenance procedure.
Long-term storage without appropriate charging can permanently reduce battery capacity.
Common Installation Mistakes
Reverse Polarity
Incorrect battery polarity can cause immediate electrical problems.
Always verify:
+ BAT → Positive
– BAT → Negative
before energizing the system.
Bypassing the Fuse
The battery protection device is an important safety component.
Never bypass or replace it with an unsuitable protection device.
Poor Mechanical Mounting
The module weighs approximately 6.1 kg, so the mounting structure must provide adequate mechanical support.
Excessive Cabinet Temperature
Battery life is strongly affected by temperature. Installing the module next to high-temperature equipment can significantly shorten its useful service life.
Insufficient Backup Testing
A battery should not be assumed to have full capacity simply because the UPS reports normal operation.
For critical systems, controlled backup testing is recommended.

Why is the backup time shorter than expected?
Possible causes include battery aging, excessive connected load, elevated temperature, insufficient charging, frequent discharge cycles, or long-term storage.
How can I determine whether the battery is aging?
Compare actual backup performance with the expected system requirements. A battery can show normal voltage while having substantially reduced usable capacity.
Why is battery temperature important?
Sealed lead-acid battery service life decreases significantly as operating temperature increases. Proper cabinet ventilation and temperature management are therefore important.
Why does the UPS switch to battery frequently?
Frequent switching can be caused by unstable primary DC power, supply voltage fluctuations, poor wiring, loose terminals, or a problem in the primary power source.
What should I do if the battery fuse opens?
Do not simply install another fuse repeatedly. First identify possible short circuits, wiring problems, excessive current, or other faults in the battery circuit.
Can the battery module be used as a standalone power supply?
It should be treated as an energy-storage component for a compatible DC UPS system rather than as a standalone regulated power supply.
How should the battery be stored?
For extended storage, the battery should preferably remain fully charged and be kept in a suitable temperature-controlled environment. Long storage periods and high temperatures can significantly reduce battery life.
Conclusion
The Siemens 6AG1134-0GB00-4AY0 Battery Module is a 24 V DC, 7 Ah SIPLUS PS UPS1100 energy-storage module designed to support compatible Siemens DC UPS systems. It provides stored energy that can maintain critical automation loads during interruptions of the primary DC power source.
Its 186 × 186 × 110 mm enclosure and 6.1 kg weight make it a substantial wall-mounted battery component rather than a small DIN-rail device. The maintenance-free sealed lead-acid construction, conformal-coated SIPLUS design, and extended environmental characteristics make it suitable for industrial control cabinets and demanding automation environments.
Correct installation requires careful attention to UPS compatibility, battery polarity, mechanical mounting, fuse protection, wiring, and environmental temperature. During troubleshooting, technicians should inspect the complete energy path from the primary DC supply and UPS through the battery connection and protection circuit to the critical load.
For long-term reliability, battery temperature, charging behavior, backup capacity, terminal condition, and battery age should be monitored regularly. In critical automation applications, periodic controlled backup testing is especially valuable because a battery can appear electrically normal while its actual energy-storage capacity has already declined.
