Wear safety glasses !
Very simple first you need a memory saver to save the memory of your car, like stereo, seat position, ect electronic stuff to keep them alive while you are changing the battery. Normally it applies 9.0 V to the cigarette lighter. just plug in.
Than find the battery and remove the negative (black wire) terminal first, and second take the positive battery terminal (red wire). And take the out battery hold-in screw and take out the battery before you put new one make sure the terminals are clean.
place the new one securely, the battery make sure doesn't vibrates other visa, vibrating might brake the plate in the battery. put positive terminal first after negative
make sure they are tight, and take the memory saver from your car.
