Should the Negative Terminal of the Car Battery Be Disconnected When the Car Is Not Used for a Long Time?
1 Answers
When a car is not used for a long time, the negative terminal of the battery should be disconnected. The reasons are as follows: 1. This is to prevent the battery from draining. 2. Generally, if the car is not used for more than a month, the negative terminal of the battery should be disconnected; if the period is not very long, it is not necessary to disconnect the negative terminal. Information about car batteries is as follows: 1. Car battery (Car-battery): Also known as a storage battery, it is a type of battery that works by converting chemical energy into electrical energy. 2. Classification: Batteries are divided into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. 3. Working principle: During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, the lead metal acts as the negative terminal, undergoing oxidation to form lead sulfate; lead dioxide acts as the positive terminal, undergoing reduction to form lead sulfate. When charging with direct current, lead and lead dioxide are generated at the respective terminals. After removing the power source, the battery returns to its pre-discharge state, forming a chemical battery.
