I agree with msgtg. I just replaced both mine with Duralast Gold's with 800 CCA and 1000 CA. I could tell a difference instantly. The truck fired right up. It used to take a few seconds for it to start.

 

03,

Why did you install two different rated batteries?

 

They are the same. They are rated at 800 Cold Cranking Amps and 1000 Cranking Amps. Same battery on both sides.

 

Thanks everyone.... I did take the other one.....that wasn't replaced and they tested it for an hour. It was dead. So you're right...You better change both at the same time. So, I installed the new batteries and it seems where the corrosion was on the negative terminal clamp, it doesn't tighten all the way. I cranked the nut really tight, but still there is a slight gap and I can wiggle it with my fingers. after hooking the two new batteries up I went to crank it, and nothing (however, now the interior lights worked) So i jumped out and wiggled the clamps to the battery terminal and wah la, she cranked over. A friend said they sell battery terminal post sleeves that give a little more width to the post so that I should be able to clamp it down tighter to the post. Anyone heard of those? this really is a great website group. I used baking soda and water to get the corrosion off the termianl clamps (man that works like a charm) i couldn't believe the corrosion coming off. I bet that for a while, I wasn't getting good charge back from the alternator and vice versa to the starter etc. I learned to check this periodically. Well..I'm learning!

 

Cool! I'm glad you finally got it resolved.
