Load Tester


  1. Test battery voltage without load, as described here
  2. Remove the test leads from the battery and connect the load tester (pictured) alligator clips or hooks to both the red and black test leads
  3. Again, touch the red and black test leads to the proper battery poles
  4. Resistor should warm considerably and voltage should drop from original reading
  5. If the voltage drops less than 0.5 volts and then stabilizes, the battery is good
  6. If the voltage drops rapidly and more than 0.5 volts or fails to stabilize, the battery should be replaced
