Battery and UPS Monitoring
Monitor UPS Battery and Efficiency
Monitor battery condition, UPS performance and the environment around your backup power system.
AKCP battery and UPS monitoring combines physical sensors with data from compatible third-party equipment. Connect AKCP sensors to sensorProbe+ and bring in UPS or battery management system data through SNMP or Modbus. Use sensorProbe+ for local monitoring, or Quicklime DCIM to bring multiple devices and sites into a central view.
- Battery voltage, current and terminal temperature
- UPS load, operating status and available runtime data
- SNMP and Modbus integration with compatible equipment
- Threshold alerts, graphs and monitoring across sites
What goes wrong with your UPS and batteries?
Pick a problem and watch it play out: the sensors catch it, your team gets the alert, the record or the camera shows what happened, and you know what to do. Example 48 V nominal bank, four batteries.
Each one plays out in four steps: the sensors detect it, your team gets the alert, the camera or the record shows what happened, and what to do next. Tap any numbered point to see what it monitors.

Simulated readings with example limits, not data from a live installation. Time outside limits holds each sample until the next one, so it is an estimate.
Monitor the battery and the UPS together
A UPS can report that it is online while a developing battery problem remains unnoticed. A room temperature reading can also miss a hot battery terminal. Looking at equipment status and physical measurements together gives your team more context when investigating an alarm.
Build a monitoring view around the questions your operators need to answer. Is the UPS carrying more load than expected? Has a battery temperature changed? Is the system running on battery or bypass? Has a device stopped communicating? These are useful signals for deciding what needs attention.
Battery monitoring with AKCP sensors
Measure battery voltage and current
The AKCP Battery Health Sensor measures voltage, current and terminal temperature on compatible batteries and DC systems. Its voltage input supports configurable ranges up to 60 VDC. Select the appropriate current sensor option for the installation.
Use these readings to establish normal operating values and track changes during charging and discharge. For a UPS battery string above 60 VDC, obtain string measurements from the UPS, a compatible battery monitor or a suitably rated transducer. Direct measurements on individual blocks also require verification of isolation and common-mode ratings for the complete installation.
Monitor battery terminal temperature
The AKCP Battery Terminal Temperature Sensor attaches to the negative battery terminal. It provides a local temperature measurement that complements the ambient sensor in the room. Compare readings over time and investigate terminals that become unusually warm relative to their own baseline or neighboring batteries.
Add visibility to existing battery systems
For compatible DC applications, the AKCP Isolated DC Voltage Sensor provides another voltage monitoring option within its rated input range. Existing battery monitors can provide additional data through their supported interfaces. Internal resistance, impedance, state of charge and state of health are available only when the connected equipment measures and exposes those values; they are not inferred automatically from a voltage reading.
Integrate third-party UPS and battery monitoring
Keep the UPS and battery monitoring equipment you already use. AKCP can collect supported data points through SNMP or Modbus and display them alongside physical sensor readings. Available measurements depend on the equipment model, communication card, firmware and published data map.
SNMP monitoring for network-connected UPS systems
A compatible UPS network card exposes measurements and status through SNMP object identifiers, or OIDs. Configure SNMP GET virtual sensors on a supported sensorProbe+ device, or monitor the equipment directly in Quicklime DCIM. Map each selected OID to the correct name, unit and alarm meaning.
Modbus monitoring for UPS systems and battery monitors
Use Modbus TCP over Ethernet or Modbus RTU over RS485 to read supported registers from UPS systems, battery monitors and power meters. A suitably configured sensorProbe+ can collect Modbus values as virtual sensors. Quicklime can also integrate compatible Modbus equipment; serial devices need an appropriate supported interface or RTU-to-TCP gateway.
For each data point, confirm the register address, data type, scaling, units and status codes. sensorProbe+ protocol support, RS485 hardware, firmware and virtual sensor licenses must match the intended configuration.
Monitor alarm contacts and external detectors
Where a UPS provides volt-free alarm contacts, connect them to suitable AKCP dry contact inputs for states such as a common fault or on-battery alarm. Compatible third-party transmitters and alarm panels can also supply signals through supported analog inputs, dry contacts, SNMP or Modbus.
Monitor the battery room and UPS environment
Add temperature and humidity monitoring around the UPS and battery cabinets. Where relevant, monitor cooling-water leaks and equipment alarm contacts. Environmental readings help operators understand whether an equipment alarm coincides with a change in room conditions.
For lead-acid installations, hydrogen detection may be part of the battery room design. Integrate readings or alarm outputs from an appropriately selected third-party detector. Lithium-ion installations require monitoring suited to the battery chemistry and the manufacturer’s protection system, including available BMS alarms and specialist detection where specified.
AKCP provides operational visibility alongside the installed protection systems. Gas and fire detection, ventilation and protective shutdown remain the responsibility of the dedicated systems selected for the facility.
