Stop driving until the charging system and battery have been checked for an overcharging condition.
The smell is not harmful. But be very careful not to inhale the fumes. Sulfuric acid can do harm to nostrils and will definitely give you a headache.
To limit the rate at which the charge is put into the battery in order to prevent overheating, boil-out of the water in the acid electrolyte, and eventually ruining the battery.
vinegar
Not necessarilly eat it, the smell attracts them, however. They then probabaly attempt to eat any electronics or objects they believe to be associated with the smell, probabaly ingesting the acid during the eating.
A battery acid is a variety of acid used as an electrolyte in a battery - usually sulphuric acid.
Yes - this is very bad and you should stop using the battery immediately. Battery acid is a very strong acid and can cause severe chemical burns if not handled properly. A battery acid leak means your battery has been damaged and may abruptly stop working.
battery acid is a mixture of sulphuric acid and Lead sulphate. Because of the high lead content battery acid should be used for nothing else but that. Lead is a commulative poison (is retained by the body so it builds up) and should be handled only in controlled applications.
the purity of the acid is 25%
You should be able to clean it up if the problem is solved. Most batteries are outside the car- I wonder why you smell it at all. Battery acid is not especially toxic, but do not drink it, of course. I suspect that you smell something else. Could there be an exhaust leak or maybe the heater leaks antifreeze into the inside of your car.
Yes it is you can use that or Lead Acid for battery acid. Good question.
No because that means that the terminals have worn out and the battery leaked acid
Do you have any sulfuric acid on hand? There is enough acid already in the battery. Just add distilled water.
