Car battery maintenance Check the electrolyte at least once a month

The service life of a car battery depends not only on the structure and quality of the battery, but also closely related to its operation and maintenance. Generally, the service life of a car battery is about 2 years, and if properly maintained, it can reach 3-4 years. At present, there are still many misunderstandings in the maintenance of batteries, which lead to early damage of batteries, which should be paid attention to.  Misunderstanding 1: When using maintenance-free batteries, simply think that maintenance-free means that there is no need for any maintenance.   Misunderstanding 2: If there is corrosion on the surface of the battery pole post terminal, it does not need to be treated, as long as it is not loosened. Corrosion appears on the exterior, and the inner surface of the terminal will also corrode, which will increase the resistance value and affect the normal charging and discharging of the battery. It must be dealt with in time.   Misunderstanding 3: When the liquid level is low, add electrolyte or add pure water instead of distilled water. If the electrolyte containing sulfuric acid is added, the electrolyte concentration inside the battery will increase, boiling, acid fog, etc. may occur, which will seriously affect the service life of the battery; use pure drinking water instead of distilled water, which contains a variety of trace elements , Has an adverse effect on the battery.  Misunderstanding 4: The density of the electrolyte is not inspected and adjusted, especially when winter comes, resulting in insufficient battery capacity and even freezing of the electrolyte.   Misunderstanding 5: When using the battery to start in winter, use the starter uninterruptedly, causing the battery to be damaged due to over-discharge.  In order to prolong the service life of the battery and avoid breakdowns such as breakdown, we should pay attention to the following points in the maintenance of the battery:   1. For maintenance-free batteries, always check the color of the electric eye. Green means the battery is sufficient; black means the battery is insufficient and need to be recharged; gray or light yellow means the electrolyte is insufficient, because the maintenance-free battery cannot be filled, the battery should be replaced immediately.  2. The battery should be securely placed on the car to prevent the battery cable from falling off due to vibration during driving, resulting in interruption of power supply.   3. Keep the surface of the battery clean. If solid oxides are found on the pole, they should be washed with hot water in time to remove them, so as not to affect the continuity between the pole and the terminal. After cleaning, wipe the surface of the battery clean, and put butter on the pole and terminal to ensure that the pole is not oxidized.   4. Check the height of the electrolyte at least once a month. For batteries without a marking line, the electrolyte can be added to a height of 10-15mm above the plate; for batteries with two red lines, the electrolyte must not exceed the upper red line, otherwise the electrolyte may overflow and form self-discharge between the positive and negative electrodes. Make the engine difficult to start, and shorten the battery life.  5. Adjust the concentration of electrolyte according to different regions and seasons. In the winter of our northeast, the concentration of electrolyte should reach 1.28 g/ml.   6. Cars that have not been used for a long time should be started every month or so, and run at a medium speed for about 20 minutes, otherwise the car will be left for too long and the car will not start when the car is in use.  7. The total time for each start of the car shall not exceed 5 seconds, and the interval between restarts shall not be less than 15 seconds. In the case that the car cannot be started after repeated starts, the reasons should be found from other aspects such as the circuit, ignition coil or oil circuit, and the engine should be started after troubleshooting. Otherwise, the battery will be over-discharged and affect the service life.
