Can you just disconnect the negative terminal on a car battery?

Q: Can you just disconnect the negative terminal? You can disconnect the battery's negative cable. All you are required to do is to locate the negative polarity of the battery and disconnect the terminal. Avoid the negative terminal to make contact with the positive one.

Is it OK to just disconnect the negative terminal?

If you remove the negative clamp and inadvertently complete a circuit to ground, there will be no current flow because the ground clamp is already grounded. Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post.

What happens if you remove the positive terminal first?

It's important to disconnect the negative side of the battery first, otherwise you can cause an electrical short if the positive is removed first.

Which battery terminal must be disconnected first and why?

Disconnect the negative terminal of the battery

You should always remove the negative battery terminal first, to reduce the risk of sparks which can make the car battery explode. Once the negative terminal has been located, use the wrench to loosen the nut that holds the terminal.

Why do you take the negative terminal off first?

The grounded terminal should be disconnected first to ensure that a battery dead-short does not occur, should the spanner disconnecting the other one contact a nearby grounded metal part. A battery dead-short will result in short circuit currents of the order of hundreds of amperes and heavy sparks.

What battery cable do I take off to check alternator?

You can check the alternator by simply starting your car and then disconnecting the negative battery cable. Be careful doing this, though, because there are a lot of moving parts in your engine compartment that could cause injury.

Will a trickle charger keep a battery from freezing?

Trickle chargers can protect a battery from freezing, but choose the proper type. Old-fashioned designs are considered “dumb.” They don't have the same control over the charge cycle as today's advanced designs. In fact, dumb chargers can end up damaging the battery, which might lead to freezing conditions anyway.

How often should I start my car to keep the battery charged in cold weather?

If you plan on not using your car for an extended period of time during snow season, it is important to turn it on every 6-12 hours and let it run idle for 15-20 minutes so that it reaches operating temperatures. This provides current to the battery, allowing it to regain its charge.

Why do you connect positive terminal first?

Connect positive first, negative having less potential won't arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.

Is it safe to touch the positive terminal of a car battery?

Tom: The danger from car batteries is not so much electrocution as it is explosion. If you touch both terminals with a metal wrench, for instance, you can create a spark that can ignite hydrogen gas in the battery. That can send pieces of battery and acid flying.

What happens if you disconnect the battery while the car is still running?

Removing the battery from the circuit allows those spikes and transients to travel around, endangering every semiconductor circuit in your car. The ECU, the speed sensitive steering, the memory seat adjustments, the cruise control, and even the car's stereo.

What happens if you disconnect the positive terminal while car is running?

If your alternator is malfunctioning by over-charging your battery, disconnecting it may allow the alternator to provide an even higher voltage to the car electronics, and potentially damage those sensitive components.
