Battery cable connectors vibrating loose

[montaillou]

Title says it all.

About every 15 hours of use and the cable connectors vibrate loose. I have the original metal battery box.

Can someone recommend a solution? Anyone ever try Nord washers? Anti-vibration mats/foam? A better battery connector?

Are your batteries tied down properly? I use marine battery terminal clamps. They seem to hold, once tightened. Also, are your terminal clamps mounted right side up (they are conical/tapered to adapt to the battery post)?
