Use of Automotive Batteries
1. If a battery is not used for an extended period of time, it will gradually discharge on its own until it becomes unusable. Therefore, it is necessary to start the car at regular intervals to charge the battery. Another option is to disconnect the two electrodes of the battery. When doing so, it is important to follow a specific sequence: first, disconnect the negative electrode cable from the terminal, or disconnect the negative electrode from the vehicle’s chassis. Then, remove the positive electrode cable, which is marked with a “+” symbol. Batteries have a limited lifespan, and they should be replaced after reaching their designated service life. When replacing a battery, follow the same sequence, but in reverse order when reconnecting the cables: first connect the positive electrode, and then the negative electrode.
2. When the ammeter indicates that the battery’s charge level is low, it is essential to charge the battery promptly. The battery’s charge level can be monitored on the dashboard. If you find that the battery is running out of power while you are on the road and the engine fails to start, you can temporarily borrow a battery from another vehicle to start your car. To do this, connect the negative electrodes of both batteries together, and the positive electrodes together.
3. The density of the electrolyte in the battery should be adjusted according to the standards specific to the region and season in which the battery is being used.
4. When the electrolyte level in the battery drops, it should be replenished with distilled water or a special fluid designed for this purpose. Never use drinking water to replace the electrolyte, as it contains various trace elements that can be harmful to the battery.
5. Continuously using the starter to start the car can cause the battery to over-discharge and become damaged. The proper way to use the starter is to limit the duration of each start to no more than 5 seconds, and wait at least 15 seconds before attempting to start the car again. If the car still does not start after several attempts, check for problems in the electrical system, the ignition coil, or the fuel supply.
6. During regular driving, it is important to check whether the small vents on the battery cover are unobstructed. If these vents are blocked, the hydrogen and oxygen generated inside the battery cannot be released. When the electrolyte expands, it may cause the battery casing to rupture, thus shortening the battery’s lifespan.
7. Check whether there are any signs of oxidation on the positive and negative electrodes of the battery. You can do this by regularly pouring hot water over the connections between the battery cables.
