Although the thread is rather lengthy and has been virtually exhausted, I am going to venture out an explanation here. Prevents Sparking or Arcing if in the event wires did touch. More energy passes from the negative (anode) to the positive (cathode) side, due to the way electrons flow, which create a potential for arcing on the positive side. So, you go to the "stronger" or more energetic side first, then you apply either the chassis or earth ground. It also puts less strain on the stator and rotor on the electric motor in your alternator. Follow or look up this enclosed link below. It gives details on arcing here. https://getjerry.com/questions/what-are-some-reasons-why-my-car-battery-sparks-when-connecting-the-charger > > They say add water to the "splash plate" but what is that? > As long as the electrolyte covers the top of the cell plates, all will > be well. Accordingly, the batteries (depending upon their chemical composition and make up) have to maintain the correct specific gravity. Most people do not know about this, but it ties in when a chemical reaction is actually created through the EMF of the battery during operation drawing from each of those cells. > starting the engine.

Actually, I heard about 13.5 to 13.8 Volts is common for vehicles and traditional automobiles with regular gasoline engines. Diesel uses up to 14.2 volts because more power is generated through the glow plugs (and with diesel, the pre-firing). I am not a diesel expert, but that is what I have heard. > Ask yourself what heating water does to its volume and you'll have > answered that question. > > And what happens if you tap water instead of distilled? The reaction will be slightly different chemically, but not by much, if the specific gravity remains intact. I try to get distilled because there is by nature less sediment in the water which reduces wear on the internal chambers or cells in the battery and less likelihood of calcification. Good Luck. Hope this helps. Charles Lucas |

Obviously, every time you connect anything to a car battery, there is a positive and a negative side to that connection as you do. Your silly reference claims there is a spark because you left something on (which on modern cars is always true) but ignores that you are connecting a charge battery with an uncharged one. |
