Which action is used to charge batteries besides the engine?

• A. Using a wind turbine
• B. Plugging into a wall outlet
• C. Hand-cranking the batteries
• D. Using the solar panel

Answer: (D)

Charging batteries without the engine relies on another energy source that can be converted into electricity and stored. A solar panel does this by harvesting sunlight and turning it into electrical energy that flows into the battery, recharging it for later use. This method is practical for off-grid or portable systems because it doesn’t require the engine to run and works whenever there’s daylight. Other sources can in different setups contribute power—wind turbines generate electricity from wind, wall outlets provide grid-powered charging, and hand-cranking delivers manual energy—but a solar panel is the straightforward, common way to replenish a battery with renewable energy without an engine.
