Integrating smart battery technology

Criterion Smart BatteriesExcell Battery’s world-leading Criterion 4 technology meets the requirements of oil and gas downhole tool users by providing complete information on battery pack usage along with the capability to analyze downhole conditions. The CR4 is integrated into batteries and provides users with capacity used, voltage, temperature, shock and vibration, rotation, and stick-slip.

Criterion 4 provides several benefits:

  • Accurate measurement of how much life is left in the battery
  • A highly reliable record of downhole conditions
  • An additional source of information to verify a downhole tool’s own data collection
  • Software-based analysis tools for recorded data

Our advanced smart battery technology also includes Criterion software: a sophisticated, intuitive, easy-to-use application for accurate data access and analysis
