How to replace a battery terminal

Model: (Various brands) Various
Part: Battery

In this video, we can see how to replace a corroded battery terminal: we remove the old terminal starting with the negative pole. We loosen the cable with a wrench and remove the nut, then move on to the positive pole and repeat the operation. If the terminal is caked with corrosion, we can use WD-40 to clean it. We apply copper grease to facilitate the connection with the pole. We cut the cable exposing the inner wire so that we can connect it to the new terminal via the nut that we will tighten with the wrench, but without overdoing it to avoid damaging the wires. To check that the connections are made correctly, the main test is to start the car.
