In this guide, we will go through the instructions that will allow us to disassemble and replace the battery of the Ducati Monster 821. First, let's put the motorcycle on the stand and start unscrewing the upper screws of the battery cover and the relay box; then, we unscrew the fastening screws located at the bottom of the battery box in order to remove it, as shown in the video. At this point, let's disconnect both battery terminals (positive and negative), and then replace it with the new original one (with the same amperage); all that's left is to reassemble everything!
