Fluke 500 Series Battery Analyzer

Battery Analyzer with Angled (No Temp) and Straight (No Temp) Probes

• Optimized user interface
• Threshold comparison
• Intercell strap resistance test and data management:
• Test probe extenders
• Intelligent test probe set (BT520 and BT521)

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


The Fluke 500 Series Battery Analyzer is ideal test tool for maintenance, troubleshooting and performance testing of individual stationary batteries and battery banks used in critical battery backup applications. The intuitive user interface, compact design and rugged construction ensure optimum performance, test results and reliability. Fluke 500 Series Battery Analyzers cover a broad range of battery test functions ranging from DC voltage and resistance tests to full condition testing using an automated string function testing and the test probe integrated infra-red temperature measurement system. 500 Series Battery Analyzers are designed for measurements on stationary batteries of all types.

Key Measurments

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.
