Battery cables and battery terminals can become loose or corroded, and like other working components, it’s important to check once in a while. By doing so you can prevent battery related problems in your ride. There are a few routine steps you can do to maintain your battery in good working condition.

Inspecting and Cleaning Top Post Terminals

Battery terminals should be inspected and cleaned twice a year, and if the terminals of cables are corroded, they should be replaced. Hiring a professional mechanic can be your last option because it is a completely easy task. Inspecting, cleaning, and replacing battery terminals and cables isn’t difficult, and you can do it yourself.

  • Just be sure that before doing the task, be sure that the engine is off and it is cooled down. Then remove the terminal caps and disconnect the negative battery cable. The cable is usually black and marked with a minus or a “neg” abbreviation.

  • Then loosen the retaining nit with the use of a wrench, and twist the connection back and forward while pulling it upwards to remove it. Once the negative cable has been removed, disconnect the positive cable using the same method.

  • Carefully clean the battery post and its terminals with a small wire brush. Brush the surface until the metal appears to be clean and free from corrosion. Dust them with a small paintbrush to remove any loose corrosion.

Do this cleaning regularly. Once you have observed that a part is damaged, replacement is needed.

Inspecting and Cleaning Side Terminals

  • Remove the negative terminals first because it is a lot easier that the others. Simply use a wrench to take off the negative retaining bolt first, and remove the cable
  • Do the same on the positive side.
  • Even if the round contacts are not corroded, take the time to clean it with a small wire brush.
  • Remove corrosion dust with a small paintbrush.
  • After cleaning, securely reconnect the terminals.

If the terminals are badly corroded it requires replacement.

Replacing Terminals

If terminals and cables a re badly corroded, they should be replaced. Here’s how.

1. First disconnect the terminals by following these steps:

· Turn off your engine and allow to cool for a moment.

· Test the battery before you change it. Maybe the alternator, which is supposed to keep the battery charged, may be faulty.

· Remove the negative battery terminal first. Take your wrench and loosen the nut. Once loosened, clearly move it away from the rest of the battery so there is no chance that it can make contact, as there is a great danger of shock.

· Work on the positive battery terminal by doing the same as what you did in the negative terminal

2. While the cables are disconnected, separate the cable wire near the corroded terminal using a wire cutter.

3. Check the wire for corrosion as well, and if it’s severely corroded, trim away the deteriorated wire. Make sure the wire can still reach the battery after trimming.

4. Before reconnecting any cables, strip off about in inch of wire insulation.

5. Install a new terminal, remove the retainer screws, and insert the wire in the appropriate location beneath.

6. Put the terminal back together, and tighten the screws.

7. Complete the process on the other side.

8. DONE

So, by simply following steps I have mentioned above, you can definitely attain a good performance in the electrical system of your vehicle. Hope this will help you a lot to attain a great convenience while driving with your precious ride!
