Across
- 6. The electrolyte solution inside a lead-acid battery, which is primarily composed of sulfuric acid (H₂SO₄) mixed with water.
- 9. The liquid solution inside a lead-acid battery that enables the chemical reactions necessary for storing and releasing electrical energy.
- 14. An electric motor that engages the engine’s crankshaft to begin the combustion process. It draws power from the vehicle’s battery and works with the ignition system.
- 15. A vehicle that uses two power sources—typically a gasoline engine combined with an electric motor and battery system
- 17. Occurs when the starter motor engages the engine’s crankshaft, causing it to rotate so the engine can start.
- 18. A measure of a battery’s ability to start an engine in cold temperatures.
- 20. Refers to electrical systems that operate at significantly higher voltages than standard 12-volt systems, typically found in hybrid and electric vehicles
- 22. Additional components and tools associated with the installation, maintenance, and service of a vehicle’s battery such as terminals, terminal protectors/covers, battery hold-downs/trays.
- 23. The process of using an external power source—usually another vehicle’s battery or a portable jump starter—to start a vehicle with a dead or discharged battery
Down
- 1. A diagnostic tool used to measure the specific gravity of the electrolyte in a lead-acid battery
- 2. Small covers located on the top of a flooded lead-acid battery that seal the individual battery cells while allowing gases to escape safely during charging and discharging.
- 3. A critical component that stores and supplies electrical energy to start the engine and power the vehicle’s electrical systems
- 4. A cleaning solution used to remove corrosion, dirt, and acid residue from battery terminals, cable ends, and surrounding surfaces
- 5. The electrical cables that connect the battery terminals to the vehicle’s electrical system, including the starter, alternator, and ground.
- 7. The electrical potential difference between the positive and negative terminals of a battery. It indicates the battery’s ability to supply power to the vehicle’s electrical system.
- 8. A battery memory saver is a tool used during battery replacement or service to prevent the loss of electronic settings and codes in a vehicle
- 10. The heat level of a vehicle’s battery during operation, charging, or storage. It is a critical factor because temperature directly affects battery performance, lifespan, and safety.
- 11. These battery connection points come in positive and negative and allow current to flow between the battery and the vehicle’s electrical components.
- 12. The primary component of the electrolyte solution inside a lead-acid battery, mixed with water. This solution enables the chemical reactions that store and release electrical energy
- 13. The system responsible for keeping the vehicle’s battery charged and supplying electrical power to all components while the engine is running
- 16. A diagnostic procedure used to check the health and performance of a vehicle’s battery under real operating conditions.
- 18. The points where the battery cables attach to the battery terminals and the associated contact surfaces.
- 19. Refers to the buildup of a white, bluish, or greenish powdery substance around the battery terminals and cable ends
- 21. Refers to the specific gravity of the electrolyte inside a lead-acid battery. This measurement indicates the concentration of sulfuric acid in the electrolyte and is a key indicator of the battery’s state of charge
