Positive
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”

What happens if you connect the negative terminal first?

It is only a safety issue.

What happens if you disconnect the positive terminal first?

If positive terminal is removed first then chances of a spark are more if this terminal touches the body through the metal spanner or wrench you are opening with is grounded accidentally and may end in flames because lot of combustible material is around.

4. Place another 3/8-inch washer onto the battery clamp.

Does it matter what order you take jumper cables off?

Disconnect the cables in the reverse order: First remove the negative cable from the car you jumped, then the negative cable from the car with the good battery. Then remove the positive cable from the car with the good battery (don’t touch a grounded part of either car with the clamp of the positive cable).

What happens when you cross the jumper cables?

Can you fit a car battery yourself?

Fortunately, this is a simple job that you can do yourself with minimal tools. A car battery is a 12V unit that plays an integral role in starting the engine. It also powers all the electrical systems in the car, including the lights, radio and electric windows.

How do I make sure my car battery is secure?

Secure the hold-down strap in its original position over the new battery, ensuring it is properly secure to prevent movement or vibration wear. Do not tighten the hold-down bracket too hard, since this can damage the plastic case and cover. Attach both cables.

What happens if you touch the positive and negative?

If the terminal remains in firm contact with the post of the opposite polarity, nothing will happen. The charge will flow from the positive post of the battery to the negative post of the battery.

What happens if you touch the positive and negative on a battery?

In fact, under normal conditions, a 12-volt car battery will usually not even shock you.The math can get a little complicated, but the main reason that you can safely touch the positive and negative terminals of a typical car battery, and walk away unscathed, has to do with the voltage of the battery.
