Battery & Charging System Test Checklist

This battery and charging system test checklist provides documented electrical system diagnostics covering battery condition, cold cranking amp (CCA) capacity, alternator output voltage, and starting system integrity. Designed for technicians performing electrical system diagnostics per SAE J537 battery test standards and BCI (Battery Council International) service guidelines. Complete this inspection proactively during oil changes and any time a customer reports starting or electrical problems.

  • Industry: Automotive Service
  • Frequency: Annually / Per Customer Complaint
  • Estimated Time: 15-20 minutes
  • Role: Service Technician / Electrical Diagnostic Technician
  • Total Items: 28
  • Compliance: SAE J537 Storage Battery Standards, BCI (Battery Council International) Standards, SAE J1495 Battery Testing Procedures, ISO 6469-3 (EV Battery Safety), OEM Battery Replacement Specifications

Battery Visual Inspection

Physical inspection of battery condition, mounting, and connections before electrical testing.

  • Battery age checked (date code) - less than 5 years old?
  • Battery case free of cracks, swelling, and electrolyte leaks?
  • Battery terminals clean and free of corrosion buildup?
  • Battery cable connections tight at battery and chassis/engine ground?
  • Battery hold-down bracket secure and preventing movement?
  • Battery vent tube clear and properly routed (if equipped)?
  • Battery brand and date code documented for warranty reference?
  • Electrolyte level visible in all cells (if conventional/accessible battery)?

Battery Load Test & CCA Measurement

Perform battery load test to measure actual cold cranking amp capacity versus rated CCA. Document all readings.

  • Battery rated CCA documented from label?
  • Open circuit voltage (OCV) reading - at or above 12.4V?
  • Load test result: battery passes at or above 75% of rated CCA?
  • Electronic battery analyzer result: GOOD / CHARGE & RETEST / REPLACE?
  • Actual cranking amperage measured during engine crank - adequate?

Alternator & Charging System Test

Verify alternator output voltage and charging system performance to ensure battery stays properly charged.

  • Alternator charging voltage at idle (should be 13.5-14.7V)?
  • Charging voltage maintained above 13V with electrical loads on (AC, lights, fan)?
  • AC ripple voltage acceptable (under 0.5V AC)?
  • No abnormal alternator noise (bearing whine or diode growl)?

Starting System Check

Verify starter motor and starting system circuit integrity.

  • Voltage drop test on starter circuit - under 0.5V total drop?
  • Starter current draw within normal range for engine size?
  • Engine cranks at adequate speed for starting (minimum 200+ RPM)?
  • Parasitic drain test performed (if battery discharge complaint) - under 50mA?

Recommendation & Documentation',

Document all electrical system findings and communicate battery replacement recommendations to the customer.

  • Overall electrical system verdict: Pass / Monitor / Replace Battery / Full Electrical Diagnosis?
  • Replacement battery group size and CCA spec documented (if needed)?
  • Memory saver used during battery replacement to preserve radio codes and adaptations?
  • New battery registration required via scan tool (BMW, Mercedes, Audi, etc.)?
  • Battery test report printed/documented and given to customer?
  • New battery warranty information provided to customer (if replaced)?
  • Old battery recycled per EPA/state battery recycling requirements?
