Need your help, my battery wont hold a charge. I have ran a load test and it shows a week battery also wont charge over 11.5 volts. I will take it to Walmart tomorrow to have them test it and replace if need. I haven't driving the truck much in the last year. I try starting it once ever 3 weeks. I connected a meter to test for a battery drain and it show 1.16 milliamps then drops to .34. What's the normal drain for a 07 chevy crew cab?

First off, personally I wouldn't take it to Walmart. Not saying that it's no different than going to Autozone to test it, I just for some reason can't trust anybody at Walmart in the shop part. I also wouldn't buy a battery form Walmart either, just keep hearing the batteries don't tend to last like they should. Maybe it's different for some, just from what I hear and have seen. But, if you said the load test showed it was weak and can't hold charge then sounds like you just need a new battery. Letting the vehicle sit like that will shorten the battery life among other things.

 

So I would just go to Autozone and have them test it. If you do need a new one then the Duralast batteries are good. At least for me they've always been good for me. I know the platinum one is a hybrid between a regular battery and an Optima.

After replacing the battery, buy a quality float charger like a Battery tender model and keep it connected when not driving

Sounds like a bad battery to me.

 

For what its worth I have a car that sits for extended periods of time with a ac delco battery from 2007.

 

My buddy has a AC Delco Battery from 2008.

 

Both cars fire right up.

 

I normally use Rural King Batteries because I buy a few a year and they are dirt cheap.

 

You will only find two manufactures of Batteries in the US Exide and Johnson Controls So I feel like buying either is a 50 50 crap shoot. lol

Well after many years of haven a battery tender it won't crank now. I ohmed pin 6 and pin 14 and have 60 ohms. I thought my bcm was shot but now im not sure. All fuses and relays are good under the hood. Not sure where to look next.

Well, if anybody was wondering what the inside of the fuse box looks like here it is. Cleaned it up and installed new fuses and it still won't start so I guess I'm off to buy another fuse box and maybe a bcm.

I know this is an old post but just keep in mind that any battery will only last between 1-5 years at most. If it last longer, you're just asking for it to straight up fail out of nowhere on you.

 

I would recommend using something like AAA (if that's something your area offers) to get a battery as it's around the going rate, has a 3 year warranty, and they come out to wherever you are located to test/replace it.

 

Past this, I hope replacing the BCM or Fuse Block fixed your issue. I would've done more testing myself like jumping the battery directly to the starter to make sure the battery and wiring/etc is okay, to rule out those items - but that's just me lol

      287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.

      Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣

      Roll up bed cover experiences

      By superdave160 · Posted

      My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      The Allison 10 speed torque converter doesn't "lock up" like the previous transmissions. It has 4 operational modes; open, slip, transition from open to slip; transition from slip to open. I have an Edge CTS3 monitor and I monitor transmission torque converter slip. Step on the gas and you get a little slip. Take your foot off the gas and you get a little negative slip. I have not found a way to display the torque converter mode beyond that. My Edge CTS3 also displays something that our trucks should already display, the current gear. I also monitor throttle body position and engine load. If I see the engine load getting too high, I'll manually drop a gear.

      Nice result. Your filter is working well  I'd have like to have seen the acid number for this sample. Curious type that I am.
