    Study Notes

    • All vehicles, electric or hybrid, have a 12-volt battery.
    • The 12-volt battery powers low-voltage components and acts as a stabilizer for the electrical system.
    • The battery must be in good condition for correct vehicle operation.
    • The vehicle will not start if the auxiliary battery is discharged.
    • Batteries work based on a scientific principle of electron flow between dissimilar metals in acid.
    • Lead-acid batteries have positive and negative plates surrounded by sulfuric acid.
    • During discharging, the plates combine with sulfur and become lead sulfate.
    • During charging, the sulfate returns to the electrolyte and the plates return to lead dioxide and pure lead.
    • There are two types of valve-regulated lead-acid batteries: absorbed glass mat (AGM) and recombinant-type.
    • Safety procedures must be followed when working with batteries.
    • Voltage of a battery does not necessarily indicate its performance.
    • A terminal voltage test is conducted with an open circuit and no load applied to the battery.
    • Load test determines the condition of a 12-volt battery.
    • Conductance tester measures how well a battery can create current.
    • Conductance tester can determine CCA, state of charge, voltage, defects, and internal resistance of the battery.
    • Conductance tester is not designed to accurately determine SOC or CCA rating of a new battery.
    • Slow charging is recommended to prevent overheating damage to the battery.
    • AGM battery requires a charger specifically designed for it.
    • Battery charge time can be estimated by using the reserve capacity rating of the battery.
    • Reserve capacity divided by charging rate gives the hours needed to charge the battery.
