Battery died suddenly?

I started having a problem with the battery in my truck: I had to jump start it the other day, and it doesn't seem to hold a charge for very long.

 

I don't drive the truck often, as a matter of fact it usually sits, unless I need to pick up something too large/heavy for my car. I've had the truck for a year and a half now, and this is the first time I've had a problem with it.

 

I keep forgetting to check for the date on the battery, so it could possibly be original.

 

I jumped the truck last week, and drove it a few miles before shutting it off. It started fine 15-30 minutes later, and after a few short trips, but when I let it sit for a few hours it cranked a little weak. A few days later it needed to be jump started again, and even after being run for a few hours it cranked weakly after sitting for about 15 minutes, so it seems to be getting worse.

 

The volt gauge reads above 14V, so the alternator is working.

 

So, has the battery just given up on me, or is there something else I should be checking?

 

TIA

Sounds like the battery gave up the ghost. One way to do a quick check is to get a meter and touch the posts on the battery with the truck off. If the batt is good, it should read around 12 volts. Anything less and its kaput.

Check the voltage of the battery after being shut down for at least 8 hrs. If it is in really good shape it should be ~12.7 volts. If it's below 12.0 volts I would recommend replacing it.

If it's a Delco battery over a couple of years old or original then it's "normal". They made some seriously defective batterys for many years. From the late '90's until a couple of years ago. What happens is that the acid inside errodes the postive terminal solder off. If you see an acid trail coming down from the postive terminal it's time to get a new battery before you end up like this. Get you another battery then twist your positive cable. Most likely the positve terminal will snap right off with ease. I've already had to trash three of my batterys, both in the '01 truck and the one from the '99 Trans Am. That and I probably sell my late model GM customers at least 20 batterys a year just because of this one issue. Just be glad you don't have one of the GM's with the battery under the rear seat. Many of those now need new floor pans.

I took a look at it, and it is a Delco, so I am going to assume it is the original battery.

 

Can anyone give me some info to help me decide what to replace it with?

Any particular brand to go with or stay away from? What are the better prices? Etc.

 

TIA

Call around to your local auto parts stores. Have the first one look up your truck to get the group size battery you need. I forget what it is off hand. Find out what brand they carry and who makes that particular brand. Also ask about warranty, cold cranking amps and price. Make an informed decision from there. The yellow batteries from walmart are pretty decent, lowest priced and have a pretty good warranty.

I had an issue with my battery a few months back. I was at a camping lot and went to start my truck after a few days and click... I used my RV battery to jump it so I wasnt stuck. Well this made me a bit weary so I went to Advanced and had the charging system checked and everything checked out good, even the battery. The guy checking it asked me if I had anything plugged in and I remembered that I had my GPS and cell phones charging and said that those things will discharged a battery pretty quick. I wouldnt have thought that a cell phone charging would do that so quickly but I havent had a problem with my battery since so he may have been right on the money.

I decided to follow your advice, Wayne. I stopped at Walmart to check their batteries, and then went to Costco, where I wound up buying the new one.

3yr replacement/100mo pro-rated, 1000CA/800CCA, Group 78, $53.

 

The stock battery was a Group 78, 600CCA. I didn't see reserve capacities listed on either one, so I don't know why the Delco has such a low capacity, for it's size.

Because it's the minimum spec. needed. They're not going to spend a penny more than they have to (unfortunately). GM is not in the habit of overbuilding or overspecing their products like some other companies are.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
