One of my battery terminal posts has gotten smaller in diameter, I assume from cleaning, general use, etc. Now, when I tighten down the battery cable connection, it tightens all the way, but the cable is still loose on the post (not real loose, but I can turn it by hand when it is fully tightened). If the post were a little thicker, it would tighten down nice and tight, but it's not thick enough anymore. Is there a way to beef up the post again so that the cable can tighten on it? I hate to replace the battery, there is nothing wrong with this battery overall, and I don't really want to try another battery cable, it is also fine. The post is just not thick enough anymore. Any suggestions?

 

you could cut a peice of brass or copper shim .005-.010 thk. and wrap it around the post,then put the cable on.

 

I know with some batteries you can replace the post. I had a die hard one time that had dual post on the + and - side that would screw out of the battery. 2001ramsport also has a pretty good idea. You wouldn't even need to wrap it arond the post , just put a small piece in between the post and the connector. You shold still get good contact.

 

Ya good idea. Thanks, i'll try that.

 

you check to, that might be covered under warrenty if you have one.

 

Warranty on my truck or on the battery? I know I don't have one on the truck anymore. I doubt i ever had one on the battery.

 

i'm going with the shim on that one. just wrap a piece of sheet metal there and you'll be fine. just make sure it's not aluminum.

 

yeah i would try the copper shim...i know you can buy small sheets (more like pieces) at ace hardware...im sure any hardware store will sell it.

 

How about using a penny? But, a guy on another forum told me that any shim not made of stainless, or lead, will set up a galvanic condition & cause corrosion.

 

Correct, dissimilar metals will corrode, and rapidly...stainless or lead.

Is the cable end all of the way down on the post? I've (carefully) taken a socket that's just larger than the post and tap the end down a little bit...never cracked a battery, and they've tightened right up. Definately not something I learned in school tho
