Battery Capacity Testing

Battery capacity testing is an essential part of battery maintenance.  Testing conforms to IEEE Standards 450, 1106 & 1188 as well as NERC PRC-005.  Capacity testing determines the overall capacity of the battery, if battery can support connected load, and to locate weak cells and faulty intercell connectors.

Temporary battery systems and chargers provided upon request.  

Load Testing includes (1 to 8 hour tests available)

  • Inspect each battery string to confirm condition for capacity test
  • Torque all connections and record resistance readings
  • Measure and record cell impedances
  • Perform visual inspection of battery system
  • Load test battery using load bank for desired timeframe
  • Record readings of each cell every hour during discharge test
  • Place battery back on charger after test is completed

A full detailed electronic report is provided detailing the battery tested, charger/UPS information, individual cell float voltages, and battery discharge performance data.  As well as specific problems during testing with recommended corrective actions.
