Can the negative terminal of the battery be disconnected if the car is not used for a long time?

[DiMarley]

When a car is not used for a long time, the negative terminal of the battery can be disconnected. Here are the specific reasons: 1. Before parking, make sure to turn off all electrical appliances in the car, such as lights, audio system, air conditioning, etc., especially small lights and turn signals. If lights are left on for an extended period, it can easily lead to battery discharge. 2. It’s important to note that even if all electrical appliances in the car are turned off, the battery will still discharge because the car itself has many electronic components that need to operate. 3. Therefore, if the car is not used for a long time, the positive and negative terminals of the battery should be disconnected to prevent the car from losing power.
