If your wrench is on the positive terminal and it accidentally touches anything metal, you will short circuit the battery.
If you disconnect the negative cable first, and reconnect it last, then the car is not electrically connected to the negative battery terminal.
While connecting or disconnecting the negative cable, you don't need to worry about the wrench touching metal parts of the car, because everything is at the same electrical potential. Side-terminal batteries, common on General Motors products, require a small socket or wrench to remove the battery cables. The industry standard with automotive wiring is Black = Ground (which is negative), and Red = Hot (which is positive).
This can be confusing when compared with wire used in buildings, where black (and other colors) are hot, and white is neutral, which has the same potential as ground.
Dirt on the surface of a car battery can create a pathway for a tiny amount of electricity to flow between the terminals. To prevent the radio from losing its preset stations, I decided to try using this 12 volt portable power supply to keep power supplied to the car while the battery is removed. I connected the black alligator clip to the engine, and the red clip to the positive battery cable.
The arms (arrow) go underneath the cable end clamp, and the center pushes against the terminal post on the battery.
Under the cap there is (or was) a round brush to clean the inside surface of the cable end clamp.
My first car had no battery hold-down clamp or strap, and since I drove like a freakin' yahoo the battery slid off its tray and rested against the alternator.
I sprayed some diluted Simple Green on the battery and used a small nylon brush to scrub the dirt and oily residue. I wondered if silicone dielectric terminal grease was meant for battery terminals, so I read the package that I had in my supply of automotive chemicals. I applied some dielectric grease to the battery terminals and spread it around with my finger. I also applied a thin film of dielectric grease to the inside surface of the battery cable ends. The good news: By connecting the portable power supply to the positve cable (and grounding the black clamp to the engine) I did not need to re-program the stations on my car radio. A clean battery with clean connections will provide the greatest possible cranking power on cold winter mornings. I think it's a good idea to do this battery maintenace once a year, preferably before cold weather sets in. Many years ago, when I was 19 and knew nothing about fixing cars, I reasoned that a recent invention called silicone caulking might work to patch a small hole or crack in the plastic case of a car battery. Treat your battery as a dangerous and toxic object that requires respect and caution and you shouldn't have any trouble changing it. To start, loosen the nut from the bolt that holds the terminal cable to the negative post on the battery. Once the cable connected to the negative terminal post has been safely removed, follow the same steps for the positive terminal. Now that both terminals are loose, it's time to unfasten any plate that holds the battery in its seat. With the battery safely away from the car, use your battery terminal cleaner to brush out any remaining sulfate from inside the terminal cable end clamps. I'm a Trini hobbyist who enjoys making new projects, doing repairs at home and improving existing systems. Now, before you rush at the poor battery with your combination wrench or socket and ratchet, a few words of advice. If you are installing a new battery, all you have to do with the old one is to take it to an authorized center for recycling. After all of this is done, it's now time to put the new battery or the old, albeit recharged, battery back into place.


A nice finishing touch would be to smear special grease over the terminals to prevent future corrosion. Remove the negative, or black, cable before removing the positive, or red, cable to avoid a fire or injury. Replacing a car battery is a relatively simple procedure most people can complete themselves in about half an hour or less. Purchasing the correct automotive battery for the car ensures it will fit and work appropriately. Before replacing a car battery, rubber gloves, a wrench, rags, baking soda, water, and a stiff bristled brush should be on hand. Mixing a small amount of baking soda with warm water will help clean any corrosion off the clamps and battery tray.
One thing to keep in mind is that most car batteries are very heavy, especially for their size. The voltage isn't harmful, but the sudden unexpected sparks will startle the $hit out of you, and could even burn you. After that you can disconnect the positive battery terminal with minimal risk, because if your wrench touches any metal parts of the car there is no complete circuit, and nothing happens.
There were two very long bolts (red arrow) that secured the bracket to the body of the truck. The alternator pully carved a nice little groove in the side of the battery case, allowing half the battery acid to leak out of one cell.
This will make it easier to read when I'm jump-starting someone's car on a cold dark winter night.
Then I went to my local garage and paid a whole dollar for them to top-up the acid in the leaking cell. Most likely, you'll encounter the same sized nut as the ones found on the terminal cable clamp or a wing nut you can unscrew by hand.
Carefully pulling the syringe plunger up to get electrolyte out, I took out from each cell until the plates were just covered in electrolyte.
Most of today’s drivers have never tinkered with such a thing and they usually go to an auto service center for such problems. Regardless of your car-related knowledge, you should have no trouble recognizing the acid-based device. If, however, you are planning a thorough recharge process, you can take the opportunity and clean the terminals with a wire brush. I have heard it is risky connecting a charger to battery while connected to car and to remove battery the BSI computer must be let go into sleep mode before disconnecting the battery, must not touch anything on car and leave car with drivers window open before letting it go to sleep, replace battery then wait a few minutes, there is then a sequence to go through before opening door, sequence includes testing of lights and such by reaching switches through open window on drivers door, failure to do this it is claimed can damage cars computers. Before replacing the car battery, the battery group number, reserve capacity, and cold-cranking amps should be written down.
Wearing rubber gloves while removing the old battery and installing the replacement car battery protects the skin from battery acid, which can cause serious burns. Using a stiff brush dipped in the mixture makes it easier to scrub off any rust or corrosion that could prevent the new battery from working. You may have to remove those clamps and replace them snugly after the new battery is installed. The battery may have a handle to make lifting easier, but it is still going to require some serious arm strength. There is so much current (amperage) available that your wrench literally becomes an arc welder. Corrosion can increase the resistance of the electrical connection, which can prevent the battery from charging properly. But I've been doing this for years and my car batteries usually last 5 or 6 years before they need to be replaced. Cracks and corrosion in the old battery can allow acid to leak out onto your skin, which can be unpleasant to say the least. You might do that as well, but in some desperate cases, let’s say your battery goes dead in some remote location and you somehow manage to get a car battery recharger, a do-it-yourself approach could be necessary.


It’s a fairly big box with two metallic connectors, one of which is most likely covered by a plastic cap. So, after placing the battery in its place and securing it, first attach the positive cable and then the negative one. The process also requires knowledge of the battery itself, how to remove the old one, how to install the new one, and important safety precautions. An automotive store or mechanic can advise customers on what type of battery to purchase based on the year, make, and model of the car if that information is not in the owner's manual. Disconnecting the negative cable first is extremely important, as removing the positive cable first could start a fire. If the car does not start after replacing the new battery, turn the vehicle off and re-tighten the cables.
I forgot to do that one time, and the car stalled because the battery cables were jarred loose. Corroded battery connectors can create so much voltage drop that the car's starter motor cranks slowly or not at all. While the car's ignition is off, the battery can still produce an electrical charge (and even an explosion) while the terminals are connected. Remember, it can be heavy, and you'll likely be hunched over it; be sure to lift with your knees. Apply a coating of corrosion protection spray to the cable end clamps to protect from future deposits from accumulating on your new battery. If your experience with cars only implies driving and refilling the windshield liquid container, the very idea of touching the battery might send shivers down your spine. As long as it is the correct size, the new battery can have a higher reserve capacity and cold-cranking amps number. Using a sturdy wrench to completely loosen the clamps attached to the battery terminals makes it easier to pull the clamps off the battery and remove it from the car. Wiggle the new battery slightly after placing it in the battery tray to make sure it is tight and facing the correct direction. Since old car batteries contain dangerous acid and chemicals, it is best to consult a mechanic or auto parts store on correct disposal methods. It's not a difficult step, but an important one. You may also want to bring the old battery with you when you purchase the replacement battery. Lifting anything heavy in a bent position can cause a painful back injury, so be careful when pulling out the old battery and installing a new one. When you do, be sure you have already placed your tools on the ground or on your Styrofoam tray to prevent sparking an electrical charge. Lift it straight up -- most batteries come with a handle attached for easy carrying -- and then out and onto the ground.
This may be helpful for people living in cold climates or those who want the car to be able to run longer if the alternator that charges the battery while driving stops working. Before taking out the old battery, the way it is facing should be noted to ensure proper installation of the new one. Also, if you notice any severe leakage and corrosion signs, it would be wise to turn to a professional to get the job done.
Because that cable is connected to the car body and if you go for the positive one first and accidentally touch any metal part with the metallic tool you will short circuit the battery (not to mention causing a shower of sparks).
The auto supply store may also give you a discount for bringing in a battery that can be refurbished and resold.
