This morning when I turned on my truck, all I got was "click-click-click"....ok, I know what that means. So I called a friend for a jump start. We hooked the cables to the drivers side battery, and was able to get a "rurr, rurr, rurrr" but the engine wouldn't turn over. Obviously it got a little more power, but not enough to do the job. I waited, let it charge a bit, and tried again, same thing, just not quite enough juice to get her started. So, I switched the jumper cables over to the passenger side battery in my truck, waited a few seconds, and then it started right up. I drove straight (30 miles) to the Ford dealer and told them I needed two new batteries. To my delight, I was told they're covered under warranty, of which I only have about 170 more miles to go before I'm out of warranty. Two hours later, they give me my truck back and say that the batteries are fine, so they weren't replaced. They checked everything and couldn't figure out why the truck wouldn't start, there's no draw when the truck's off, the connections are good, the batteries are supposedly good. Obviously something's wrong, I was wondering if the 30 mile trip charged the batteries enough that they would read as "good" or does that not matter? We were both perplexed, but they are keeping the truck overnight to check it again in the morning to see if the batteries held their charge. Do any of you have any other suggestions? I'm worried because something is wrong, and I'd like to get it fixed before my warranty's done. Wow, this is long, sorry, I guess I should end it now. TIA

P.S. Oh yeah, it's a 2005 F250 6.0 with 35,830 (or something close) miles

 

You have the problem documented now so if you go over 36,000 miles you have something to go back on. If you have one bad battery it will drag the other one down with it. I would pull both batteries out and have them tested at an auto parts store.

One thing that might have happened is that the batteries could have been low. If the passenger side battery is closer to the solenoid then you will be able to start the truck easier.

 

sounds a lot like the right battery may be bad,but dealer should have a good tester to test them
yes a 30 mi drive or less would charge batteries where it would start

 

wow you guys are fast! Thanks so much for your responses, and that gives me a little peace of mind MisterCMK, that I can use this visit to fall back on if I go over 36,000 and my whole truck explodes ;-) I'm just worried that it will be something crazy that will be expensive....but you're right, I didn't think of that, at least something's on file that there was a problem pre-warranty expiration.

 

Like I said earlier, take both of the batteries up to the local parts store and have them tested. When you replace batteries in your truck you should always replace them in pairs as one bad battery will drag the good one down.
