Install a New Car BatteryInstalling a battery for your car is a very easy task that can be done with a few simple tools. Anybody with a little mechanical knowledge can perform the task.Battery Placement and SecurityBegin by placing your battery carefully onto the battery platform. Make sure the platform is clean of debris so that the battery sits level. Then take the battery bracket, which is used to hold the battery in place, and tighten it down using a socket wrench. Now that the battery is securely held in place, be sure to check that you have everything else in place before connecting the battery.Connecting The BatteryBefore connecting the battery, it's a good idea to place a protective rubber casing over the connection so that it sits between the battery cable and the battery casing. This will prevent any corrosion of the casing to occur. Start with the positive battery cable. Place it over the terminal connection until it is all the way down and the terminal is sticking out above the terminal. Tighten the cable securely to the terminal with a wrench. Repeat the same procedure with the negative battery cable and you will be good to go.
