  • Wear protective gear to protect yourself from battery acids that could burn your hand. Pop the hood after putting on safety goggles and gloves to protect your hands and eyes.
  • Find the battery’s location in the hood. It is typically seen in the left-hand corner, next to the windshield. It is affixed to two cables, as you shall see.
  • The darker of the two cables are colored (-). The ground (negative) terminal is located here. This cable needs to be unplugged first. To prevent short circuits, always disconnect this cable before the positive cable.
  • Removing the positive cable clamp with the wrench allows you to disconnect the other cable from the positive (red) (+) terminal.
  • You can see a bracket with bolts holding the battery in place if you look at the bottom of the battery. Leasing it up requires a 13 mm wrench. By raising it by hand, remove the battery from the vehicle and then place it aside on a concrete surface.
  • Use a rust-remover and wipe the battery cables with sandpaper before installing a new battery. You can use this to help get rid of any leftovers and accumulations from the old battery.
  • Make that the battery you purchase has the same specifications as the old one, including the part number, size, and capacity.
  • Install the fresh battery, secure it with the bracket, and tighten the bolt with the 13-mm socket wrench. To avoid corrosion and acidic buildups, lightly coat the two terminals in dielectric grease.
  • First, reconnect the positive cable. Re-tighten the 10-mm bolt with the socket wrench after placing the cable over the terminal. The terminal cover, if present, can then be placed over the terminal.
  • The negative cable should then be connected by being reattached to the negative terminal. Using the 10-mm socket wrench, tighten the bolt once more.
  • Make sure nothing is moving and that neither the battery nor the cables are. Close the hood before attempting to start the car. Verify that everything is functioning correctly.
