Before You Start

There are a few things you will need to change a dead car battery – a new battery that is suitable for your vehicle and a socket set to complete the removal and installation.

Main Steps

The first thing to do is get the old battery out of its housing bracket, which requires the loosening of the clamp nut followed by the removal of the cable that connects to the battery’s negative terminal.

Repeat this action to take the cable off the positive terminal, and then turn your attention to the clamp that is keeping the battery in place. Again, refer to the car’s manual if you need specific information on how a particular mounting system operates to avoid errors.

Once the battery is free, remove it with care and put it to one side, and then take a look at the tray and see if there is any corrosion that needs to be removed before you proceed.

Reverse the entire process to install the new battery – putting it in place, adding the clamps and affixing first the positive and then the negative terminals with the relevant cables.
