  • 1. Once the power supply unit of your car is off, you can get to taking your car’s battery out. Since it is held fixed with the help of a special retainer, you will, definitely, need two spanner wrenches. One should be 10 mm and the other one should be 13 mm. Open the hood of your car and take the battery terminals off the battery. You should do it the following way: at first, you take off the negative terminal (there may be drawn a “minus”) and, only after that, you take off the positive terminal (“plus”). It is necessary to follow this rule in both cases: whether you’re dealing with fuel-injected engine or carbureted engine. If you take the positive terminal first and, accidentally, let it touch any area of your car’s body, a case of short circuit will occur. Short circuit may lead to fire. In order to keep yourself safe and the car undamaged, you need to start with taking off the negative battery terminal. If, while taking the battery terminals off, you notice that they are sparking, it means that some devices of your car are not turned off (the car’s compartment lighting etc.)
