How to replace battery terminals, video of the replacement process
Replacing battery terminals is not the most difficult task that car owners have to face, so there should not be any particular difficulties in the process of this work.
The battery terminals are put on the battery electrodes and connect voltage cables to them, which provide the car's electrical network with current. Terminals are made from different metals - brass, lead, copper, aluminum. They come in different shapes and types, but one thing unites them - over time, oxidation appears on them, they rust and literally crumble before our eyes.
If you notice that it is time to replace the terminals, then you first need to purchase a new kit and start replacing them.
Each terminal has a designation - minus and plus, the negative contact of the battery, as a rule, is thicker. Stop the car on level ground, turn off the engine, turn off the ignition, put on the handbrake and put it in neutral.
Then you need to remove the terminals from the contacts. They are attached with 10 or 12 bolts, unscrew and remove. You need to remember:
- first you need to remove the negative contact - minus, ground. If you violate the sequence of removing the terminals, a short circuit may occur and all electronics will burn out.
- Then we disconnect the positive contact from the battery electrode. You have to remember which wire is which.
Cables are attached to the terminals with clamping bolts and inserted into special fasteners. If the cable length allows, then you can simply cut the end of the wire with a knife or any sharp object at hand, if not, then unscrew the bolts with keys of the appropriate diameter. If there are no keys at hand, you can take pliers, an adjustable wrench, in extreme cases, you can stop someone and ask for the necessary tools.
After removing the terminals from the battery contacts, the latter must be cleaned of scale, oxides and corrosion with sandpaper or a brush.
You can also get rid of oxides with a solution of soda with water, after which the contacts must be cleaned. So that they do not rust, they are lubricated with grease, lithol, technical petroleum jelly or special anti-corrosion varnishes.
When you figured out the battery contacts, you need to insert the wires into the terminal holders so that the ends of the wire protrude slightly from under the mount. To do this, you need to strip the insulation and braid of the wire with a knife and get directly to the copper wires. Tighten the holder bolts to the maximum. First put on a positive contact. Then, in the same way, put the wire on the negative terminal.
When the battery is reconnected to the car's electrical system, you can try to start it. As you can see, there is nothing particularly dangerous and complicated here. The main thing is not to confuse minus and plus.
