What is the correct way to use a car battery?

[Victoria]

Here are the precautions for using a car battery: 1. If a battery remains unused for a long time, it will slowly self-discharge until it becomes unusable. Therefore, the car should be started periodically to charge the battery. Another method is to disconnect the two electrodes from the battery. Note that when removing the positive and negative electrode cables from the terminals, the negative cable should be disconnected first, or the connection between the negative terminal and the car chassis should be removed. 2. When the ammeter indicates insufficient charge, the battery should be charged promptly. The battery's charge level can be displayed on the dashboard. If you find the charge insufficient during a trip and the engine stalls and cannot start, as a temporary measure, you can seek help from another vehicle to jump-start your car by connecting the negative terminals and positive terminals of both batteries. 3. The density of the electrolyte should be adjusted according to the standards for different regions and seasons. 4. When the electrolyte level is low, distilled water or a dedicated replenishing fluid should be added. Never use drinking purified water as a substitute, as it contains various trace elements that can adversely affect the battery.
