  • Requires no configuration, so it's quick and easy to use at every service interval, providing test results in seconds
  • Uses actual engine starting load, vastly improving accuracy over load testers and eliminating the need to compare results with hard-to-find battery specifications
  • Automatically adjusts for battery and engine size, eliminating conversions, the need to look up reference values, and complex configuration before each test
  • Automatically compensates for ambient temperature (most models), so is fully functional in extreme environments
  • Displays information clearly and intuitively toggles between functions, making it fast and easy to use
  • Easy to maintain, as it has no internal battery
  • Compact and stores easily
