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.
