Battery actually long "hair"! May rainy season, how do we maintain the car?

This year's plum rainy season is particularly long. Plum rains have lasted for almost a month in many places in the south. The wet, sticky and sultry weather, returning to tide and moldy, is really uncomfortable and brings travel. A lot of influence. But, you know what? In fact, the car battery can't stand this climate! Recently, many car owners reported that the car did not start smoothly. When they opened the hood, the battery actually grew green "hair"? Battery end post turned "green" In fact, this is a signal that the battery needs maintenance. Because there is a lot of moisture in the air during the rainy season, and these moisture are mixed with acidic substances and various impurities, the moisture in the air is easy to oxidize with the positive and negative electrodes (lead) of the battery to form green oxides. In addition, long-term corrosion will affect the conductivity of the positive and negative electrodes of the battery, causing the vehicle to fail to start normally; in severe cases, short circuits of wires will occur, which will damage the positive and negative connecting lines of the vehicle battery, and increase the hidden dangers of the car. The battery is not maintained for a long time The old driver asked, does the battery need to be maintained? Not to say "maintenance-free battery"? In fact, this is a misunderstanding, maintenance-free is for the inside of the battery, and the external terminal post of the battery needs to be maintained regularly, otherwise the terminal post will be oxidized over time due to air humidity and bad usage habits, which will cause damage to the terminal post wiring harness of the battery and affect the battery life. Battery maintenance Some car owners will use some soil methods when maintaining the battery, such as scalding the battery end post with boiling water and then applying butter. In fact, butter is used for lubrication and cannot be used to eliminate end column oxides. Moreover, it is easy to absorb dust when applying butter, and in high temperature weather, butter melts and flows, which is easy to be confused with acid leakage. It is suggested that professional tools should be used for battery end post maintenance. It is recommended that all vehicle age models, every 1-2 years, a professional end post maintenance, to prevent the oxidation of the battery end post and wiring harness, to ensure reliable connection between the battery and the vehicle, to delay the decline of battery performance, to prevent accidental breakdown of the vehicle. In addition, for those car owners who have had vehicles for more than 3-5 years, especially those who have had symptoms such as dim headlights and weak start, it is recommended to check the health status of the car's battery and replace it with a new battery based on the test results.
