Yesterday morning it was in the mid fifties here in TN. I went out to start my truck and it would turn over but not start. I had noticed a few times in the last couple of months that it was a little slow to start but didn't really worry. My first thought was glow plugs or glow plug module. So, I logged on to FTE and saw several posts about batteries being the culprit. I tried jump starting with my Chevy (sorry). It would turn over a little faster but still not start. The voltage on both batteries read about 12.6 volts. I removed them and took them to a local alternator and starter rebuilder for load testing. One was definitely bad and the other was about 40%. I installed two new Interstate batteries and much to my surprise it fired up. Without FTE I don't think I would have suspected the batteries. Thanks guys.
Good to know, what year is your truck? I'm wondering if it's almost time to swap out mine before i get stuck. Here's a potentially stupid question, if i were stuck somewhere and needed a jump, does it matter which battery (driver vs passenger side) you hook the cables up to???????? One of those things i never thought of before!
i had to replace the factory batteries in my 04 last march or so... pissed me off cos i really didn't have the $$$ at the moment for 190 bucks worth of batteries. and it doesn't matter which one you hook up to for a jump. believe i've jumped or been jumped from both, nary a problem.
This last month I have noticed a slightly slower cranking speed on my truck and if I have the interior lights or stereo on for awhile I notice a difference in starting so I think they are getting ready to die. I am going to change out the batteries soon so i don't end up stuck somewhere!!!
My truck was built in may of 2005 and has the original batteries.

With that info, I don't think I would have suspected the batteries either. I would have suspected an oil pressure problem.
My 03 has original batteries; this winter will probably kill them. It cranked slow on the colder mornings last year.

The primary battery is on the passenger side of the engine compartment. That would be the correct battery to 'jump' from.
Its amazing to me the disparity between all of our trucks when it comes to batteries. I just had to replace mine (07) and the increase in cracking speed was major.
Even when I got it brand spanking new it didn't crank as fast as it does now.
You have to wonder ..........

well you have to factor in how many times the salesman started it up for other potential buyers before you got to it and i know that the truck didn't run long enough to charge them back up. that constant discharge and short charge from idling for 5 minutes or less will kill a battery. also i'm not sure what the stock batteries are rated at cause mine had been changed before i bought my truck but the new ones you put in could very well have more CCA's which would make it turn over faster.
My truck is an '04. I first noticed that the batteries were getting weak about two weeks ago. I was replacing a front wheel bearing & hub on my truck. I had the radio on for most of the day and noticed that when I cranked it, it was very slow. But, it did start. I guess what had me unsure if it was the batteries, is that it would not start when I tried to jump it. But, when I put in new batteries, it fired right up.
