Are the negative terminals of new car batteries always loose?

[McOwen]

The negative terminal of a new car battery should not be too loose, as excessive looseness can lead to poor contact and cause sudden power interruptions. Here are some battery maintenance measures: 1. Avoid leaving the air conditioning on when the engine is off: The air conditioning consumes a significant amount of power. Some drivers have the habit of not turning off the air conditioning before shutting down the engine, which causes the air conditioning to automatically start the next time the vehicle is turned on. This results in an instant high power load on the battery, leading to long-term damage. 2. Prevent battery discharge: To avoid battery discharge, pay special attention not to use the car's CD player, cigarette lighter, or other charging devices for extended periods while the engine is off, as this consumes a large amount of battery current. Discharging the battery can easily cause damage to it.
