- 01Inside the 12V BatteryExplain how a vehicle battery stores/delivers energy and why voltage alone does not prove health.20 min
- 02Flooded, EFB, AGM and Auxiliary BatteriesIdentify common low-voltage battery types and why correct technology/specification matters.20 min
- 03CCA, Ah, State of Charge and State of HealthInterpret battery ratings and distinguish charge level from actual battery health.20 min
- 04Professional Battery TestingChoose and interpret appropriate battery tests instead of condemning from one voltage reading.20 min
- 05Battery Cables, Terminals and Ground StrapsDiagnose cable and ground faults that mimic battery or starter failure.20 min
- 06Fusible Links, Mega Fuses and Battery Fuse BlocksSafely trace high-current power leaving the battery and identify protection/distribution faults.20 min
- 07Battery Monitoring SensorsUnderstand what battery monitoring sensors measure and how bad data can alter energy-management behaviour.20 min
- 08Battery Registration, Coding and Replacement StrategyRecognise when battery replacement is more than physical fitment and avoid configuration errors.20 min
- 09Dual-Battery and Support-Battery SystemsTrace dual-battery architecture and determine which battery/system is responsible for a symptom.20 min
- 10Diagnostic Case: Power Supply FailureProve whether a low-voltage complaint originates in the battery, distribution, monitoring or return path.20 min
