Here's why:
* Lemons don't produce electricity: While lemons can create a small amount of electrical current through a process called "galvanic corrosion," it's nowhere near enough power to start a car.
* Car batteries require significant power: Car batteries need a high voltage (usually 12 volts) and substantial amperage to provide the power needed to crank the engine.
* Lemon batteries are a science experiment: The "lemon battery" is a fun science experiment demonstrating basic electrical principles, but it's not a practical source of power.
To start a car, you need a conventional car battery. These batteries use chemical reactions to store and release a large amount of electrical energy.
