Re: Loose Battery Clamp...
If with the old battery the clamps were tight but now with the new one, they are loose, or not able to be tightened like they were before, could the the posts have been machined or molded smaller or on the bottom side of a tolerance ?.
What kind of ends are on your cables now ?. The reason I'm asking is sometimes installing car audio I have used some aftermarket gold plated brass replacement cable ends and they sometimes did not tighten like I would like as they were either poorly made or due to the material they were made out of were a lot harder to try and shrink the hole by tightening a set screw or allen screw on them. Also on these brass type terminal ends, once tightened they don't spring back to how they were when new and sometimes I have had to take the bolt out to spread the clamp open some and then reassemble things.
Keep in mind too, that the battery posts are of two different dimensions to where if the wrong terminal end is used on a particular post the terminal may bottom out and not be able to be tightened or the hole shrunk anymore limiting the clamping force onto the post.
Touching on the spring eye end cables, I bought some for my 68 Chevy II Nova as well as a new battery and have had them on and off a few times but on those they are limited to the clamping force and if opened up too far even once, they will not spring back to where they were before creating now a looser connection. Luckily the battery posts I have seen are tapered some and this might help if the clamp is lowered onto the post as it then is larger and might allow for more clamping force off of the battery cable ends if they too are lowered onto the posts.
