Key features

The ideal test tool for maintenance, troubleshooting and performance testing of individual stationary batteries and battery banks used in critical battery back-up applications

  • Key measurements – Internal battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency and temperature.
  • Sequence measurement mode – Automatic or manual sequence testing of battery strings with automatic measurement storage including voltage, resistance and temperature (with BTL21 intelligent test probe), eliminating the need to press a button each time a measurement needs to be saved.
  • Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on the-go analysis.

Product overview: Fluke 500 Series Battery Analyzer

Reduced testing complexity, a simplified workflow and an intuitive user interface provide a new level of ease-of-use in battery testing.

  • The ideal test tool for maintenance, troubleshooting and performance testing of individual stationary batteries and battery banks used in critical battery back-up applications
  • The intuitive user interface, compact design and rugged construction ensure optimum performance, test results and reliability
  • Covers a broad range of battery test functions ranging from DC voltage and resistance tests to full condition testing using automated string function testing and the test probe integrated infra-red temperature measurement system
  • Designed for measurements on stationary batteries of all types.

Voltage and resistance thresholds

Fluke Battery Analyzers allow you to quickly and easily define upper and lower measurement thresholds or tolerance ranges. During the testing process, measured values are automatically compared to the predefined threshold levels producing a PASS, FAIL or WARN indication after each measurement. A maximum of 10 sets of thresholds can be stored and threshold indications are determined based on the following criterion:

VoltageResistance
> Voltage Lower< Voltage Lower< Reference> Reference and Reference x (1+Warning %)> Reference x (1+Fail)
PassFailPassWarningFail

Fluke battery management software

Fluke Battery Management Software Easily allows you to quickly and easily import data from the battery analyzer to a PC. The measurement data and battery profile information is stored and archived with the Management Software and can be used compare results, switch results between conductance and resistance readings and perform trend analysis. All measurement data, battery profile and analysis information can be used to easily generate reports.

  • Quick view saved readings
  • Profile management
  • Histogram of a battery string with end user defined threshold
  • Historical trend data of batteries
  • Multiple rounds of discharge voltage
  • Quick Report Generation
  • Upgrade Fluke Battery Analyzer firmware
  • Switch measurement results between conductance and resistance readings

Fluke Battery Analyzer mobile app

The BT521 offers wireless communication for data download and remote display while measuring via the dedicated Fluke Battery Analyzer mobile app (note: the Fluke BT521 is not currently Fluke Connect compatible). Using the Fluke Battery Analyze mobile app you can:

  • Browse profile
  • Review sequence testing data
  • E-mail sequence testing data

Fluke BT510 key features:

  • Battery Voltage – During the internal resistance test, Fluke Battery Analyzers also measure the voltage of the battery under test
  • Discharge Volts – The Discharge mode collects the voltage of each battery multiple times at a user defined interval during a discharge or load test. Users can calculate the time a battery takes to drop to the cut-off voltage and use this time to determine the capacity loss of the battery
  • Ripple Voltage Test – Measures unwanted residual ac component of the rectified voltage in dc charging and inverter circuits. Allows users to test ac components in dc charging circuits and find one of the root causes of battery deterioration
  • Meter and Sequence Modes – The Meter mode is used for a quick test or troubleshooting. In this mode you can save and read the readings in a measurement or time sequence. The Sequence mode is for maintenance tasks with multiple power systems and battery strings. Before a task starts, users can configure a profile for the task for data management and report generation
  • Threshold and Warning – Users can configure a maximum of 10 sets of thresholds and receive a Pass/ Warning/ Fail indication after each measurement
  • Intercell Strap Resistance Test and Data Management – Measures the resistance of the intercell connection between batteries in a string.
  • AutoHold – When AutoHold is turned on, a reading is captured when it remains stable for 1 second. The reading is then released when a new measurement starts
  • AutoSave – When AutoSave is turned on, measured values are saved to internal memory automatically after an AutoHold reading is captured
  • Fluke Battery Management Software – Easily import data from the Product to a PC. The measurement data and battery profile information is stored and archived with the Management Software and can be used for comparison and trend analysis. All measurement data, battery profile and analysis information can be used to easily generate reports
  • Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on the-go analysis
  • Optimized user interface – Quick, guided setup ensures you're capturing the right data every time
  • Battery life – 7.4 V 3000 mAh lithium-ion battery for more than eight hours continuous operation.
  • USB port – For fast data download to supplied data analysis and report management application software.
  • Highest safety rating in the industry – CAT III 600 V, 1000 V dc max. rated for safe measurements all around the battery power supply equipment.
