Putting water in a battery can lead to dilution of the electrolyte solution, which may disrupt the chemical reactions necessary for the battery to function properly. In lead-acid batteries, adding distilled water is sometimes necessary to maintain the electrolyte level, but adding too much can cause the battery to overflow and reduce its performance. In other types of batteries, such as lithium-ion, adding water is inappropriate and can lead to short-circuiting or dangerous reactions. Overall, it is crucial to follow manufacturer guidelines regarding maintenance and electrolyte levels.
Yes
Nothing it will not harm the battery at all. It is sealed from outside elements. I do not mean putting it under the water as that would short it out. But to rinse it off is fine.
Your putting a charge on the battery when its running.
by putting a battery
No. Water will not burn, although the hydrogen and oxygen that make it up are both highly flammable. It is possible that putting a battery in water could create those gases by electrolysis under some conditions.
There is no fool proof way. Get a new battery if putting it on a slow charger does not work.
No. That would defy the point of putting the battery there in the first place.
No. It does not require very much power. If the battery is not putting out enough power to turn the starter, but is putting out some power it may still work. If the battery is totally dead it will not work.
No unless you leave it in there for months. Want to drain it, the connect something to the battery and leave it on.
battery water is distilled water
Well, if have pure water, the water molecule is electrically neutral, so it is not drawn to either terminal. Once a battery is dropped in the water, the sodium ions migrate towards the negative-tank and the chlorine ions migrate towards the positive-tank.
Use distilled water. If the battery is a sealed battery you cannot add any water.
