Can a leaking car battery cause spontaneous combustion?
1 Answers
Yes, a leaking car battery can cause spontaneous combustion. When a car battery leaks, it results in reduced acid levels inside the battery, leading to higher internal resistance during charging and discharging. This generates more heat, which increases the float charge current. The battery's expansion raises the temperature further, eventually causing thermal runaway and spontaneous combustion. Causes of battery leakage: Poor sealing between the upper cover and the base tray can lead to cracks, while leakage from the safety valve or wiring connections can also cause battery fluid to escape. Solutions: Inspect the battery's exterior for any cracks. Plastic welding can be used to repair leaks, along with adding an appropriate amount of sulfuric acid and distilled water. Check the safety valve for signs of leakage—if found, repair or replace the valve. If the battery case is severely damaged and most of the electrolyte has leaked, replacement is the best option. Maintenance tips for car batteries: Before turning off the engine, ensure all electrical devices are switched off. Avoid long-term parking; start the vehicle at least once a week to maintain optimal battery voltage. Regularly clean the car battery. Over time, dust, white powder, and stains can accumulate on the battery, potentially shortening its lifespan. Use a damp cloth to clean and wipe the battery periodically, keeping its exterior as clean as possible.
