<p>I always found the hexagonal crimpers to not work well with the
thinner lugs that we usually use for batteries. The hex crimpers
are good for the UL listed heavy wall lugs however. I have a

on one side and V on the other. That type works well for thinner
wall lugs. I have had a Greenlee model, and currently have a
chinese one that is fine, its similar to this:</p>
