My battery cage came loose
If you notice that the battery makes a noise while driving, it is possible that the battery tray (the part where the battery sits) has become loose. If left loose, it can damage the battery pins and cause interruptions in battery power.
Fixing a loose battery tray is really easy. You will only need 2 zip ties/zip ties and 2 minutes of your time to tie the front of the battery tray to the frame of your Pulse.
Once the tray is fitted, the battery should not move or make any noise while driving.
This is what your practical work will look like when finished:
