Car battery?

Ok so this mite be a stupid question but it bugs me



So here it goes my understanding is that water is a conductor of electricity so there for if u had o light on a 9v battery then but the battery in the water it would not work so why can a car battery go in water without any protection ?Car battery?
Pure water is an insulator, it is only the impurities in it that allow it to conduct.



Water in a battery is there to dilute the electrolyte and has nothing to do with whether it insulates or conducts
Water is a conductor. A poor conductor.



So the drain will be VERY slow and very little.





Good luck...Car battery?
its waterproof
water is a poor conducter howerver salt water is way better at conduting electricity so it all depends and not all batterys are sealed some have vents and caps on them so saying they are water proof is crapCar battery?
What do you mean by a car battery "going in water"? Surely you aren't considering submerging a car in enough water to completely cover over the battery?!? Or are you thinking of the amount of water that a battery, properly installed inside the engine compartment, might receive if the hood of the engine compartment was open in a downpouring rain? Believe me, if you rigged up something to completely submerge both poles of the battery in any auto, you would be providing a direct short across the poles, and depending on the volume of water you supplied between the poles, your might have a rapid boiling of the water and a badly weakend battery -- if the amount of water was small enough that it all boiled off before the battery went dead. Otherwise the battery, before long, would be stone-cold DEAD!
pure water is a poor conductor, add a little salt and it will conduct, if tot generate electrical energy. the car battery is pretty well sealed from the elements.
