Using the ED-18 Battery Tester

NOTE: For setup, customization, and other available features, refer to the ED-18 user's manual.
  1. Connect the leads to the positive and negative terminal of the battery.
  2. Use the arrow keys to select the Battery test, then press ENTER, then follow the prompts.
    NOTE:
    • Make sure to enter the correct cold cranking ampere (CCA) rating of the battery. You can find the CCA printed on the label on the top of the battery. If the CCA rating is not entered correctly, the test result will not be accurate.
    • Make sure you select FLOODED for the battery type.
  3. Here are the four possible battery conditions:
    • GOOD BATTERY: The battery has at least 60 percent of its charge and good state of health. No action is required.
    • GR8 DIAGNOSTIC TEST NEEDED: The battery voltage is low. Connect the GR8 and use the diagnostic test to determine if the battery is GOOD or needs to be REPLACED.
    • REPLACE BATTERY: The battery condition is poor. Replace it.
    • BAD CELL: There is a problem with the battery. Replace it.
