How to connect the battery power switch

It is actually very simple to connect the battery of the car to the power-off switch. Install an electromagnetic switch on the bus from the negative pole of the car battery or the ground wire, and then the control circuit of the electromagnetic switch is controlled by the ignition key. The car battery is equipped with a power-off switch, that is, a general relay is installed on the car. When the ignition switch is turned off, the power of the whole car will be cut off, so as to prevent the battery from leaking. When you are not driving, you will not worry about battery power loss if you simply cut off the power.

Under normal circumstances, the service life of the battery is 2 to 3 years. It is closely related to the use of the car. If the following four things are done, the battery can maintain high efficiency for a long time:

1. Use batteries frequently. If the car is not running for a long time, the battery may be insufficiently powered and its service life will be greatly reduced;

2. Pay attention to the cleaning of the two electric piles. As long as the car shakes, the electrolyte will emerge from the electric pile, and the electrolyte will produce some chemical reactions in the air, which will affect the normal operation of the battery;

3. Check the generator regularly. Because the battery needs a generator to charge it. As long as the generator fails, the battery may also be greatly affected;

4. Check the electrolyte regularly. The battery's job is to use the electrolyte inside to cause a chemical reaction, and the electrolyte will volatilize over time, and the battery cannot work normally.
