I'm not sure what's wrong with my battery, but it's just not getting good connections anymore. The battery, cables, and everything is clean, no rust. I think it might be where I have a new job and it takes me over some pretty rough road and it's shaking the cables loose. It's making my car stutter when I'm driving and usually the next time I start it up after I get back from work I have to go and shake the cables a little bit so they'll get good connections before I can start the car. Is there some grease or something I can put on the screws that hold the cable in to fix this?

 

If you have one of GM's 5 yr. batterys, get rid of it, I learned that almost every one of them are faulty after mine leaked acid all over my A/C hoses after only 2 yrs. of service.

 

If the roads are that rough, you don;t need grease, you need a BIG (Chevy)Truck!!!

 

Like "SFB767" said.
There were problems with some of the Delco Bat. Specifically loose/bad bat terminals.

 

it could be the posts themselves have come loose from inside the battery. i have seen that before.
