The batteries will blow up with ground problem as well. I have read all the responses and I guess I'm still confused. If you connect each pole of one battery to the opposite pole of the other, you will have completed an electrical circuit, and electricity will flow. Most vehicle batteries today are filled with a charged acid solution that expels gasses and is highly explosive. Center 7500 lbs Scissor Stabilizer Jacks.

Because the wrench or socket is touching the live part of the electrical connector.

The positive + terminal is red, as are most of the 12v wires powering each little component. As for a short circuit, in order to get a short circuit, I have to provide a complete circular path for current to flow through. The battery cable connection turns white with a white residue due to buildup of electrolyte acid on the terminal. Since retiring from the news business in 2008, Kirchhoff takes care of a 12-acre rural Michigan lakefront property and applies his experience to his vegetable and flower gardens and home repair and renovation projects.

Do not attach 12V to 24V. Also make sure, not to touch the car like leaning on it while you are touching the positive red connector or you could get shocked. If I hook the negative terminal of battery 1 to ground which we will arbitrarily define as zero volts , and hook the negative of battery 2 to the positive of battery 1, then the negative of battery 2 will come quickly to equilibrium at 9V relative to ground. When you remove the wire, you take away some of those electrical forces that act on the charges near the terminals there were charges on the wire after all, held there by a chain of charges leading back to the other battery where there are chemical forces. Now, when you are connecting the lug on the positive lead, if the spanner comes in contact with frame or any common Ground terminal, it results in a dead short on battery which may possibly explode the battery. The charge buildup on the terminals does exist as an equilibrium between chemical and electrical forces, but the charge buildup at the surface of an unconnected battery must be relatively small.

For added security, you can remove the battery and connect it to the charger in a separate location from the vehicle. However, well you take care of your batteries, there will come a point when it will die and will have to be replaced. If the positive post is disconnected first there is the possibility of shorting out the battery by touching the body with the wrench while loosening the terminal. With regard to arching, connecting or disconnecting either terminal in an otherwise continuous circuit will draw a spark. So you say that the potential difference reaches zero after the connection. When two poles are connected through a simple wire assumed to of no resistance the result of the above expression becomes infinite anything divided by zero.

Attach the positive terminal first, and the grounded or negative terminal last. Modified landing gear jacks, etc. You can also apply a small amount of anti-corrosion grease both on the battery posts and the terminals as an added measure.

I applied some dielectric grease to the battery terminals and spread it around with my finger. Once all connections have been made, start the good car and let it run a minute or so, revving it moderately. A massive short circuit welded his ring to the holddown and to the wrench, which in turn was welded to the positive terminal. And so it will take only a small amount of charge flowing from one battery to the other to equalize the potential difference between the terminals. If the negative lead were already attached, then touching the positive lead to just about anything on the car that is metal would short out the battery. The terminals and cable ends are made from lead, which corrodes readily.
