What to Do About Car Battery Leakage?
2 Answers
Car battery leakage solutions include visual inspection, internal maintenance, and leakage detection. Specific related introductions are as follows: Visual Inspection: It is necessary to inspect the appearance of the battery, checking whether the casing is cracked. If there are small holes or overflow on the leakage surface, plastic welding can be used to patch it up. After patching, you can use a hydrometer to measure the density of the battery fluid and add an appropriate amount of sulfuric acid and purified water as needed. If it's evaporation, simply add some fluid. Internal Maintenance: If the first step shows no issues, remove the panel and check whether the safety valve has any signs of leakage. If not, proceed to the next step; if there is, the safety valve needs to be repaired or replaced. Leakage Detection: If the first two steps show no abnormalities, a pressure test is required, which involves pressurizing and inflating in water to check for bubbles. If bubbles appear, it indicates leakage; if not, it is normal.
I once encountered a car battery leaking acid. That time, on a hot day, I opened the hood and saw wet acid stains and white powder buildup, which gave me a scare. Knowing that the electrolyte is highly corrosive and can rust metal wiring, I immediately put on thick rubber gloves to protect my hands and used a wrench to disconnect the battery's negative terminal to avoid the risk of a short circuit. Then, I sprinkled baking soda on the leaking area to neutralize the acid, waited for the bubbling reaction to finish, and rinsed it thoroughly with plenty of water. After that, I checked the battery casing for any cracks or signs of aging and found that the battery terminals were severely corroded, so I bought a new battery to replace it. Usually, I make it a habit to clean the battery terminals every quarter, wiping off the oxidation layer with a damp cloth to prevent corrosion and leakage. If not addressed promptly, battery leakage can affect starting performance and even damage components under the car. So, I recommend everyone to work in a well-ventilated area and, if unsure, seek help from a repair shop for a safer and more reliable solution. Prevention is more important than repair, especially for old batteries that need regular replacement.
