I tend to be proactive and replace my batteries after 3 years so I don't run into trouble. However, I'm still on my original in my 16 1500 crew cab Silverado 5.3. It looks like swapping it out is a bit of a project, and I can't see the battery label without removing that bus bar with the connections. The manual also didn't have the specs listed. So, does anyone know the factory battery specs? I wouldn't mind stepping up in capability while I'm at it. Thanks.

I just changed out the battery on my '15 Sierra about 3 months ago for the same reason. I installed the Interstate MTX-94R H7. Living in a cold climate area, I opted for a few more cold cranking amps (850).  I got a good deal at Costco, but afterwards I had read somewhere that they allegedly get the batteries that have been sitting for a while (not sure of truth behind that).  The videos that show how change it out and what needs to removed are pretty spot on.

I'll jump in here with my opinion.....When I change out the battery on my '17 Silverado 5.3l, I'll put in an H7 AGM one & will probably put in the DieHard Platinum AGM Battery, Group Size H7, 850 CCA from Advance Auto, OE Group H7; OE CCA 720; Battery Spec: 850 CCA; 1000 CA; 140 Min. I believe it's a step up from the factory one. Just my opinion.

94RPG is the factory ACDelco replacement battery.  800 CCA, 140 Reserve Capacity, 80AH, so already a rather stout unit.  The 94RPG comes with a 42 month free replacement warranty so any failure in that 42 month window gets you one free replacement.  No prorate.    

One thing to keep in mind too is Reserve Capacity is more important than CCA.  You can have a 1000 CCA battery but it could have a low reserve capacity.

What is reserve capacity (RC) and why do battery manufacturers bother to mention it? The Battery Council International (BCI) has created a group of standardized specifications that help give consumers an apples to apples comparison from one product to the next. Cold cranking amps is one of those specifications, as is Reserve Capacity. So what is Reserve Capacity? It is a time measurement that explains how long a fully-charged battery can deliver 25 amps of current in an 80°F-environment, before the battery is discharged down to 10.5 volts.

Shouldn't cold cranking amps be enough by itself? Not really, as CCA and RC both describe two different functions of a battery. Cold cranking amps will help you understand how much power the battery is capable of delivering in relatively-short bursts, while reserve capacity helps you understand how a battery can deliver energy over an extended period of time. Why is this important? Because sometimes vehicle charging systems fail and when that happens, the battery is then responsible for all the vehicle's electrical demands. For example, if your serpentine belts breaks in the middle of the night, your battery will power your headlights, windshield wipers, electric pumps and other electric accessories that are needed to get you to safe location.

Or this?

One thing I like about AC-Delco batteries is that they have a date code which I believe is an estimated date placed in service date to allow for shipping and dealer turnover time. In the case of the battery in this picture it's February of 2016, the P followed by the 026 R. No matter where you buy your battery or whether it has a date code, not a bad idea to drag along your multimeter to check the voltage on that supposedly fresh battery before you walk out the door with it.

I had to replace the battery in my ‘16 a couple months ago. Went with a Duracell from Batteries Plus Bulbs. From my research, the Duracell batteries are a relabeled Deka.

I also have a 2016. Built in Dec 2015. I purchased Jan 2016. Battery was getting weak and replaced in Jan 2021. I also opted for the Interstate MTX-94R H7. Paid $158 at my local mechanic, and it came from the distributor the day before. Could I have saved? Maybe, but it was under MSRP on Interstate site and it was a local small business. Getting the old one out was far worse than putting the new one in, for me anyway.

My 2018 stock battery (prob 2017 manufactured) is “ok” but I can only get 30 min of radio at 70% volume before I get the low battery start truck warning. Stock bose radio but aftermarket 10” sub with 300w amp. 
 

only way to listen to radio without it turning off after a few mins is key on correct? When camping, tailgating, etc

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      By dna9656 · Posted

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
