  • Turn off the engine and put on the parking brakes. Please do not smoke or allow anyone wandering around smoking near your work area.
  • Open the hood and use the prop rod to keep it open.
  • Now locate the car battery with two cables attached to it.
  • Next comes locating the positive and negative terminals of the car battery wherein the positive terminal is denoted with a (+) sign and the negative terminal is denoted with a (-)sign.
  • Disconnecting the negative terminal socket before the positive one is important as doing otherwise may cause short circuit. So by using the wrench, loosen the clamp of the negative cable.
  • Once that is done, disconnect the positive terminal as well.
  • Unfasten the battery holder and remove the bolts, nuts and clamps holding the battery.
  • Now comes removing the battery which needs to be done very carefully as it is quite heavy. You might want to consider getting help if you think it's too heavy for you to lift.
  • After the removal of the old battery, use the water and baking soda solution to clean the battery tray and also the terminal clamps.
  • Let it dry and then install a new battery. For this, place the new one from where you removed the old one and make sure that the positive and the negative terminals are on their respective sides.
  • Use the nuts, bolts and clamps that were removed earlier to fix the new battery.
  • Using a wrench again, tighten the clamps to fix the positive terminal first and then the negative terminal.
  • Close the hood and start the car to check if it's working fine.
