How to Install a Car Battery

Male mechanic changing car battery

Many drivers may think that installing a car battery is an easy process, while true, there are steps to take to ensure you’re handling the installation safely. For starters, make sure you have the right tools and genuine OEM parts: Wrenches, battery cleaning solution, a new battery, wire brush, pliers, and anti-corrosion spray are all needed. You also want to make sure that you wear thick rubber gloves for protection. Finally, be careful when moving the battery to avoid spilling battery acid. Don’t hesitate to contact the service department if you have any questions on your car battery installation near New Braunfels.

Car Battery Installation Steps

  1. Start with the engine turned off and the parking brake activated. Open the hood and find the battery. Loosen the nut connecting the black cable (negative cable) from the battery using the wrench. Specific battery wrenches or pliers will make things easier.
  2. Once loosened, twist and pull the cable off. If it’s stuck, don’t try to pry it off, because it can damage the battery.
  3. Use the same steps to remove the red battery cable from the positive terminal.
  4. The battery hold-down clamp keeps the battery from moving around in the engine. Loosen then remove it.
  5. At this point, you can remove the battery. Take it out, but be careful and use both hands. The battery is heavy, and dropping can cause an unsafe leak.
  6. Remove any corrosion that might be in the battery tray or hold-down clamp. You can use a baking soda and water solution or a battery cleaning product to do this.
  7. Take a wire brush and clean off the battery cable connectors using the same cleaning product as above.
  8. Now, it’s time to install the new battery. Place it in the battery tray and tighten the hold-down clamp.
  9. If you have an anti-corrosion solution, spray it on the positive and negative terminal of the new battery before connecting. This helps prevent corrosion and extend the life of your battery.
  10. Attach the battery cables to the battery terminals, connect the red cable first, and then the black cable.
  11. Double-check that the connections are secure, then try to move the battery. This is a great way to check that it won’t move.
  12. Start the car. If you have any issues, consult with the San Antonio-area battery experts at INFINITI of Boerne.
