Your battery's been sliding around the chassis every time you brake hard, and you can hear it shift on the washboard road. That's not just annoying – it's how terminals corrode and batteries crack. This small Jaycar tray is pressed from 1.2mm mild steel with a vinyl coat that shrugs off oil and acid. Cruciform slots line up with your existing chassis mounting holes, and the built-in cutouts take hold-down rods so the battery stays put. Not recommended for marine salt water – if you're on the water, look at the HB8100 box instead
