DLV-Max Battery Voltmeter & Specific Gravity Testing Kit

Model # DLV-Max-Kit

The DLV-Max Battery Test Kit includes the DLV-Pro Data Logging Voltmeter with the SG-Ultra Max Digital Hydrometer for a complete solution to battery voltage and specific gravity testing. The DLV-Pro battery voltage meter measures and records cell voltages in less than 1 second, enabling rapid testing of battery cell voltages. Voltages are recorded in two formats: 8 strings of 256 or 20 strings of 48 readings. Specific gravity testing and temperature readings measured from the SG-Ultra Max are directly uploaded to the DLV-Pro in 8 strings of 256 format. Both voltage and specific gravity test readings can be combined into a single report.

What are some common applications areas for this product?
Common applications include but are not limited to:

  • Forklift / Motive Power
  • Telecommunications
  • UPS Testing
  • Power Utilities
  • Mission Critical Facilities

What parameters does the DLV-Max measure?
The standalone DLV-Pro Battery Voltmeter measures cell voltages ranging from 0-16V. Specific Gravity (SG) readings can be imported to the device and tied to specific voltage readings with use of the included Eagle Eye SG-Ultra Max Digital Hydrometer.

How does the Discharge Test functionality work?
During a discharge test, the DLV-Pro can be used to measure up to 11 voltage readings per cell. These readings can be transferred to the software for analyzing and reporting. The unit itself does not perform a discharge; external test equipment such as load bank would be required to produce the load on the battery system.


  • Record, view, & analyze cell voltages with statistical & graph analysis
  • Integrates with SG-Ultra Max Digital Hydrometer for specific gravity values
  • Targeted applications include: Telecom, Utilities, & Motive Power
  • Optional memory configurations to best suit a variety of applications
  • Perform a full battery discharge test & analyze results on-site during the test
  • Replay animated discharge tests
  • Export test data to PDF reports or Excel spreadsheets
  • 1-year Warranty

More Info

The DLV-Max battery test kit can be used to perform a full discharge test on up to 256 cells by recording up to 11 time-stamped voltage readings for each cell, along with time-stamped load current readings and initial and/or final SG readings via the SG-Ultra Max. The DLV-Pro provides immediate onsite analysis of all battery test data including threshold,statistical and graphical reporting, battery and individual cell discharge curves. The DLV-Pro will display a graphical analysis that includes battery voltage vs. time & selected cell voltage vs. time, as well as display statistical analysis (sum, average, max/min readings with cell number). All test data can be uploaded to a PC using the included Winmeter 5.1 Battery Analysis Software via a USB 'plug in play' interface. Winmeter 5.1 has power report generation and database capabilities. The DLV-Pro can also export the readings to a USB flash drive or print the data directly to an optional IRDA printer. The user has full control over the data and can edit, delete or insert test data prior to creating a battery analysis report.

DLV-Max Kit Includes:

  • DLV-Pro Battery Voltmeter
  • Voltage Leads
  • SG-Ultra Max Digital Hydrometer
  • Sample Tubes
  • Belt-clip
  • Voltage Leads
  • NIST Calibration Certificate
  • Mini-USB Cable
  • AC/DC Power Supply
  • Eagle Eye USB Flash Drive
  • Carrying Case
  • Winmeter Battery Analysis Software

In addition to the products listed above, the DLV-Pro and the SG-Ultra Max have a 1-year warranty and the DLV-Pro comes with a NIST (National Institute of Standards & Technology) Certificate with test data.

If specific gravity values are not necessary, Eagle Eye offers just the DLV-Pro Voltage Testing Kit to test battery voltage - without the SG-Ultra Max Digital Hydrometer. The DLV-Pro also includes Winmeter 5.1 Battery Analysis Software for battery voltage trending and reporting.
