Step 6 · Interpret Test Results

Evaluate the results from both the voltage and load tests. If the static voltage is low (below 12.4V) and drops significantly during the load test (below 9.6V), the battery is likely bad and needs replacement. If the static voltage is good but the load test fails, the battery is also likely faulty. If both tests pass, the battery is probably in good condition, and the starting issue might be elsewhere (e.g., starter or alternator). Consult battery condition charts if available for specific readings.
