Why Does the Battery Leak?
2 Answers
Reasons for battery leakage: During use, if the battery outputs excessive current or undergoes continuous discharge for too long, the battery temperature rises, which can easily lead to leakage. Prolonged discharge with small currents can also cause leakage, and continuing to operate below the nominal voltage may result in leakage. Battery leakage inspection and handling methods: First, conduct a visual inspection to locate the acid leakage area; remove the cover to check for any signs of acid leakage around the safety valve, then open the safety valve to inspect for any flowing electrolyte inside the battery. After completing the above steps, if no abnormalities are found, proceed with an airtightness test. Finally, during the charging process, observe whether any flowing electrolyte is produced. If so, it indicates a production-related issue. During charging, any flowing electrolyte should be completely extracted.
I once encountered a situation where my car battery leaked, mainly due to three reasons: First, overcharging the battery, such as using high-power electrical devices for extended periods on the highway, which can cause excessive pressure inside the battery, leading to acid spray. Second, a cracked or damaged battery casing, possibly caused by rough roads or accidents. Third, aging issues, as the sealing compound in the battery deteriorates over time, leading to slow leaks. In my case, it was during the summer when the car was parked outside for too long in high temperatures, and I later found corrosion marks on the floorboard, which was quite alarming. Battery leakage not only damages the car's paint but can also harm people due to the corrosive nature of the acid. Since then, I've developed a habit: regularly checking the battery for any bulges or cracks, minimizing electrical usage after turning off the engine, and ensuring a long warranty when replacing the battery. It's also advisable to have the battery voltage tested at a repair shop once a year to prevent minor issues from becoming major hazards.
