What To Do If Car Battery Is Leaking?
If your car battery is leaking, immediately put on protective gloves and eyewear to avoid contact with corrosive acid. Ventilate the area to disperse fumes. Avoid sparks or flames—leaking electrolytes are flammable. Neutralize spilled acid using baking soda and water (1:1 ratio). Disconnect the battery terminals (negative first) and replace the battery. Pro Tip: Never tilt a leaking battery—acid spillage accelerates.
How dangerous is battery acid exposure?
Battery acid (sulfuric acid) causes severe burns and respiratory issues. Skin contact requires 15-20 minutes of water rinsing. Inhaled fumes? Move to fresh air immediately. Example: A 2023 NHTSA report showed 12% of EV battery incidents involved improper acid handling.
Can I temporarily seal a leaking battery?
No—sealing compromises safety. Cracks often indicate internal pressure buildup from overcharging or thermal runaway. Temporary fixes risk explosions. Instead, isolate the battery outdoors on a non-conductive surface like concrete. Real-world case: A sealed AGM battery ruptured 3 hours after minor leakage, damaging a Tesla Model 3 charging port.
| Action | Risk Level | Alternative |
|---|---|---|
| Epoxy patch | High (thermal runaway) | Professional replacement |
| Duct tape | Moderate (acid seepage) | Baking soda neutralization |

FAQs
Use EPA-certified recyclers. Retailers like AutoZone offer free drop-off—never landfill. Leaking batteries incur $10k+ EPA fines if mishandled.
Does insurance cover battery leakage damage?
Comprehensive auto policies often do if leakage wasn’t due to negligence. Document photos pre-cleaning for claims.
