How do you safely change the battery on a Suzuki gz 250?

Have the Bike okk, and engine switch off. Take the right cover off. It has a screw close to wher the seat begins. to the top left fo the cover. then pull the cover out, it will snap off easy. The with a scredriver unscrew the black cable, ( negative ) first, and the the red, and then just loose the strap and take it off. pretty simple task..
