What to Do When the Car Battery Burns Out?

Solutions for a burnt car battery: 1. Remove the battery, charge it once with a charger, clean the rust at the connection points, and reinstall the battery; 2. Use a multimeter to measure the contact resistance of the battery terminals. If it exceeds 100 milliohms, the contact resistance is too high—either replace or clean the terminals. If not, the battery must be replaced. Reasons for a burnt car battery include: 1. Short circuit: The car has many complex electronic components and circuits. A short circuit can damage these components and also cause the battery to burn out; 2. Overcharging: Most battery damage is caused by prolonged overcharging; 3. Electrolyte loss: The battery contains electrolyte. Leakage indicates the need for immediate replacement to prevent damage to other circuits; 4. Complete discharge: Repeated and prolonged complete discharges accelerate battery aging and shorten its lifespan.
When the car battery burns out, I immediately pull over and turn off the engine to prevent further issues. If you smell smoke or see flames, call 119 for emergency assistance to ensure your safety and others'. Afterwards, avoid touching the battery as it may be hot or pose chemical risks—contact a nearby repair shop or roadside assistance for inspection and handling. I once encountered this situation due to an aging battery causing a short circuit. Trying to remove it myself only made things worse, so I ended up spending some money to replace it. Regularly avoid leaving the car idling for too long while playing music or using electrical devices, as excessive power consumption can easily damage the battery. Periodic checks on the battery’s condition are also crucial—for example, use a home charger to replenish power if the voltage is unstable during charging.
