I have lost one of the plastic screws on my car battery.
Since they are not a part that is being sold, my options were limited to buying a new battery or to become creative.
I took a wine cork (from cork tree) plugged the hole, then made some turning and it seemed to grip on the grooves since it resisted being pulled out. So at least temporarily problem is solved with acid not spiling out under the hood while I am driving.
I am wondering about the longevity of this solution. What I am worried about is acid melting of some of the cork and that corkwood/acid solution mixing with battery acid and ruining the battery, or maybe getting on fire.
What damage can I cause by plunging a car battery section hole with wine cork? What are my other options?
