What to Do About Car Battery Leakage?

[OPatrick]

Solutions for car battery leakage are as follows: 1. Visual Inspection: It is necessary to inspect the exterior of the battery to check if the casing is cracked. If there are small holes or overflow on the leaking surface, plastic welding can be used to patch them up. After patching, the concentration of the battery fluid can be measured with a hydrometer, and an appropriate amount of sulfuric acid and purified water can be added as needed. If it's due to evaporation, simply top it up with more fluid. 2. Internal Inspection: If the first step shows no issues, remove the panel and check for any signs of leakage around the safety valve. If there are none, proceed to the next step. If there are, the safety valve needs to be repaired or replaced. 3. Leakage Check: If the first two steps show no abnormalities, a pressure test is required. This involves pressurizing the battery with air underwater to check for bubbles. If bubbles appear, it indicates a leakage. If no bubbles are present, the battery is functioning normally.
