Is it necessary to replace a leaking car battery?

It is not always necessary to replace a leaking car battery. The decision depends on the specific situation. Here are the methods to deal with a leaking battery: 1. Cracks on the exterior: If the battery is leaking, it is likely due to aging or even cracking of the seal between the upper cover and the base. In this case, first inspect the battery's exterior for any cracks. If found, use plastic welding to repair them. After repair, also check the electrolyte concentration to ensure the battery functions properly. 2. Leakage from components: The leakage might also be caused by issues with the safety valve or wiring connections. First, remove the battery panel and check for any signs of leakage from the safety valve. If present, the corresponding parts should be repaired or replaced. 3. Severe electrolyte leakage: If the electrolyte is leaking severely (emptying in a short time) and the above methods cannot resolve the issue, it is crucial to replace the battery immediately. Otherwise, the leaked electrolyte (containing strong acid) will corrode the car body or components around the battery, leading to higher repair costs than just replacing the battery.
During my last long-distance road trip, I encountered battery acid leakage, which scared me into pulling over immediately to inspect it. The acid had spilled everywhere, corroding the battery tray and nearby wiring. If left unattended, it could have damaged other electrical components, corroded the vehicle frame, or even caused a short circuit leading to a fire. I found a roadside repair shop, and the technician said the leakage indicated an aging battery or a cracked casing, recommending a direct replacement. After the swap, the car started much more smoothly, and looking back, it was quite a scare. I usually advise car owners to regularly pop the hood and check the battery's condition, addressing any abnormalities early before they escalate. Safety first—spending a bit on a new battery is far better than taking risks.
