What Causes Battery Leakage?
3 Answers
Car battery leakage is caused by cracked sealing glue, leakage from the safety valve, or acid leakage at the terminal connections. Below are the methods for handling battery leakage: Plastic Welding Treatment: If you find cracks in the casing or minor leaks from tiny fissures, you can use plastic welding to seal them. Additionally, check the electrolyte concentration to ensure the car battery functions properly. Battery Replacement: If the electrolyte leakage is severe, it is recommended to replace the battery directly. Since the electrolyte is highly acidic, it can easily corrode the car body or surrounding components, leading to high repair costs.
There are several reasons for battery leakage. The most common is overcharging. If the charger you use has excessive power, the high current can generate too much gas inside the battery, and the excessive pressure on the casing can cause it to crack and leak. Aging is also a critical factor. After four or five years of use, the plastic casing of the battery becomes brittle and can crack with slight pressure or impact. External factors also play a role, such as driving on particularly bumpy roads, where long-term vibrations can loosen or damage the sealing ring. Temperature fluctuations should not be overlooked either. Expansion in summer heat or contraction in winter cold, along with frequent thermal cycling, can fatigue and crack the materials. I've dealt with such issues myself and found that it's important to clean the leakage area promptly, as the fluid is highly corrosive and can damage metal components. It's recommended to check the battery's condition every six months—be alert if you see white foam or detect an acidic smell. When parking, try to choose a flat area to minimize vibrations, and use the original charging equipment to reduce risks. Remember, safe handling is crucial—don’t attempt repairs casually.
I've experienced battery leakage before, when I was new to driving and didn't pay attention to maintenance. One of the main reasons was improper charging - I used a non-matching charger which caused overcharging, leading to battery swelling and leakage. Another factor was aging; after prolonged use, the battery casing became brittle and cracked from excessive vibration on bumpy roads. Cleaning up was not only troublesome but also caused corrosion to some engine parts. Since then, I've learned to regularly check charging voltage and drive slower on rough roads to reduce shocks. Daily maintenance is simple: glance at the battery monthly for cracks or color changes, and avoid parking in direct sunlight during summer to minimize thermal expansion risks. Battery lifespan is typically around five years - beyond that, leakage becomes more likely and it's time for replacement. Simple actions can prevent major issues, like wiping off surface dirt during car washes to keep it clean.
