일반적으로 축전지는 가솔린 자동차, 디젤 자동차 할 것 없이 모든 자동차에 설치되어 엔진을 기동할 때의 점화, 조명 등의 전원으로 사용된다.Generally, storage batteries are installed in all vehicles, whether gasoline or diesel, and are used as a power source for ignition and lighting when starting an engine.

또한, 각각 다른 금속으로 만든 양극과 음극의 전극과 전해액으로 구성되어 있으며, 양 극을 도체로 각 전극의 작용 물질과 전해액이 가지는 화학적 에너지를 전기적 에너지로 끌어낼 수 있게 되어 있다.In addition, it is composed of electrodes and electrolytes of the anode and cathode made of different metals, respectively, and it is possible to draw the chemical energy of the working material and the electrolyte of each electrode to the electrical energy by using the anode.

이와 같은 축전지는 각종 전기장치와 연결되어 각 장치의 사용에 따라 방전되어 소모된다.Such accumulators are connected to various electrical devices and discharged and consumed according to the use of each device.
