CELLTRON Advantage

CELLTRON™ Advantage

The CELLTRON Advantage has the capability to test Valve Regulated Lead Acid (VRLA) and Vented Lead Acid (VLA) batteries. It is capable of providing Battery Voltage down to one (1) volt and measures inter-cell and terminal connection resistance.

  • Conductance based diagnostics, proven effective for identifying and trending battery health
  • Highly efficient test processes: 50% reduction in test time compared to other battery analyzers
  • Less invasive testing approach that reduces battery discharge, voltage measurement skew, and allows for more tests on a single internal battery without recharge


The CELLTRON Ultra offers advanced battery testing capabilities for effective evaluation and maintenance of all stationary power systems.

  • Software and data management techniques allow user to establish battery reference values when data is not available, for reference-free testing
  • Stores over 250 pre-established reference/benchmark values to assist in the development of battery pass/fail thresholds
  • Enhanced conductance methodology enables accurate and repeatable testing in the presence of ultra-high electrical interference
  • Versatile multi-meter features allow for the measurement of AC and DC voltage and current. Scope function displays AC ripple current and more
CELLGUARD Wired Installed


The CELLGUARD Wired Battery Monitoring System (BMS) delivers economical, yet highly accurate and reliable remote health analysis of stationary batteries in applications with high electromagnetic noise.

  • The control module records critical performance elements including alarms and discharge events. Alarm parameters and thresholds are managed through the control module which also delivers real-time system data through the web-based CELLTRAQ™ Battery Asset Management Software.
  • One battery sensor module per battery is capable of monitoring internal resistance, voltage, and temperature, delivering a comprehensive battery state of health analysis.
  • One string sensor module per string, in conjunction with a string current transducer provides monitoring of the string voltage, current, and ambient temperature.
