Sure, if there is one, but this is the 1st I'd seen evidence of one. No one associated with the vehicle could or would tell me.
I just called up my local dealer and asked them that very question about what that battery sensor was for and they pretty much said that it was there to both protect the PCM and protect the battery itself like if the battery was overcharging or if it was getting hot or anything else. Now, I didn’t ask him this, but he never said anything about the battery sensor allowing the usage of both a regular battery in an AGM battery.

I also asked about using an AGM battery in my truck and the service writer didn’t think it would be bad and even the guy in the parts department at my local dealer said that because I have a sound system in there, that he actually recommended using an AGM battery but going back to what the service writer said when I asked him about whether or not though this would affect my warranty, all he said was only if the battery caused whatever the issue was, and I was like, well hell, that can happen with any battery no matter what type it is.

I’ve been reading all over the place, not just here where people claim to use these AGM batteries in a car that did not come with this type of battery that say they’re not having any problems. Or in other words, their car doesn’t know any difference from the AGM battery to the Regular ole, cheaper battery the car came with or what they’ve used all these years.

That’s what I meant about people saying they haven’t had any problems.

What I'm saying is they aren't getting fully charged if you don't drive them daily. They won't hold a charge as long as a garage queen as a flooded cell battery, because that gets charged fully if the alternator is set only for flooded.

I noticed my high priced AGM got weak after a week without a wall charger. So what's the point in having an AGM? For rough duty like boats and atvs that bounce around, sure. But not for driveway queens. Why pay more for nothing at all?

I sent an email to Alexey, asking what he knew about the Battery ID 1-15.
He said he had no information but would poke around to learn what he could.

That’s all perfectly understandable so do you think I should just replace my battery with another one like what I already have? As I said, I’m only wanting to do what’s right and the only time I would spend the extra money on this type of battery is if it would be beneficial.

And the other thing is, it’s starting to sound like what I need to do, no matter what kind of battery I buy is being that I do have a sound system in here and being that my truck does sit a lot sometimes and it makes a lot more short trips than anything that maybe once a month, I need to take my battery charger out there, and spend the afternoon charging the battery so who knows, if I start doing that even if I buy basically the same kind of battery that got in there now, it might actually last a bit longer. What do you think?

The idea of getting a NOCO vehicle mounted charger for these electronic monsters is not a bad idea. Some day I may put one in mine as it is a Driveway Princess and does not get run enuf to charge up the AGM to 100% SOC. But my system adjusts for the AGM as far as I can tell, just got nothing in writing. You ask 10 dealer guys, U get 10 aha answers, kinda like that old game where you whisper a phrase to one person, go around the room and end result silly.

I've had the same big ole Group 31 AGM in my truck since 2017,and it was still starting the truck perfectly fine and passing a toaster test load test when i sold the truck a bit ago.I never touched the charging system in my 14 ,to use an AGM battery,and the group 31 is quite a bit more battery then the little factory H7 battery is.
This is the battery that's been in my truck for 8 years.I do use a Noco charger to keep it topped up when the truck is parked for the winter.I also have 2 master disconnect switches,the bumper mounted one shuts the truck down when it's running to be NHRA legal,the one on the battery box kills everything,if the trucks not running,but won't shut the truck down if it's running,should slow up any thief,lol




Your battery is kept inside the truck. I wonder if that makes a difference.

That makes me think..... I don't remember ever replacing the battery in the wife's Durango. Her battery is inside, under the passenger seat. We bought that car in 2015. I'm gonna go look.

OP: According to 2018 manual, you have a permanent battery gauge in your instrument cluster: You just gotta hook up your meter and see where needle pointing means ref appx voltages than: Only thoughts I have. I am assuming you have the Premium Cluster and Not Base Cluster, Your avatar says you have a Limited Truck, so assuming Premium cluster. (# 2) in diagram.

Lol, yea. The battery in her Durango is still strong as a dose of the Filipino Clap!

Having the battery inside,protected from engine heat in the summer and somewhat protected from the cold in winter must be helpful.

Here's the date sticker on her Durango battery.

That's 1 months before we bought it used in El Paso, so the dealer must have put that battery in right before they sold it to us.

It's in the very back corner of the box Ken,so basically not much differant then being under the hood,i have measured temps under the tonnue in the summer of 130F,so i guess it'd be a bit cooler then underhood temps in the summer,but it has really long cables to reach up front,lol. The front box is my stand alone fuel cell,the back box is the battery box

So, in the summer, it isn't subject to the additional heat of the engine and radiator baking it in the engine well.

Take a look at your negative battery post Brian,or better yet get us a picture of it,if it has a weird looking connector,that'll be the IBS /intelligent battery sensor ,and as far as i know it was added in 13 to the majority of Chryco vehicles.
If you have something that looks similiar to this on the negative battery post,you have the IBS sensor



I would if it weren't 6 feet up in the air on a hoist. :cool:

I've never used my digital thermometer to measure underhood temps in the summer,but i have used it to measure the side of the battery box under the tonnue in the summer,and have seen temps of upwards of 130F,so it's probably about 70 degrees cooler then it would be under the hood.Even with cables about 18ft long,the stock alternator seems to have no issues with keeping it charged though,as i didn't delete the IBS sensor in the system,it's still tied into the negative side of the truck,but it's roughly in the factory spot under the hood,and not actually on the battery post

I'm pretty confident you'll have the IBS sensor on your 17

Ok. Well, then regardless what battery I got, not driving the thing for a week drains any battery from all the technoglitz devices. I think I remember you put in a disconnect switch?

I ended up mounting a CTEK smart charger on the wall and plug it in if I'm not driving the next day. So again, what's the point in getting an AGM? Maybe it will last a couple of years longer for 50% more price?

I have left the truck sit for well over a month with the battery still connected several times with no charger on it,and i've never had any issues with it starting,but then again the AGM i'm using is quite a bit more battery then the stock H7 battery is. When i threw the battery on a scale it was 64 lbs,so you know you're carrying something when you latch onto it's handle,lol.You can check the specs on the battery i'm using,it's a fairly robust battery.

  • Offers more than 2x the cycle life of regular AGM batteries and 4X the cycle life of conventional flooded deep cycle batteries
  • Withstands deep discharges allowing you to take advantage of more of the battery's rated amp hour
  • Accepts the maximum amount of amps that an alternator or battery charger can deliver for astonishingly fast recharges
  • Truly maintenance-free: no messy or dangerous acid spills
  • Mounts in virtually any position, no gassing (under normal charging), never requires water to be added and brass terminals will never build corrosion
  • Stores for up to 2 years on a full charge with no loss of capacity, ideal for off-season storage
  • Up to 28X more vibration resistant than a conventional marine battery to handle the roughest waters or terrain
  • 2150 Pulse crank amps, 1370 marine crank amps, 103 amp hours, 220 minute reserve capacity
  • Dimensions: 13" L x 6-3/4" W x 9-3/4" H (330 x 170 x 635 mm)

That thing is a monster! Much bigger than mine. Maybe I should have put in an H8?

Regardless of the battery chemistry used, my SLA is not happy with my SOP.

I often drive far too short a distance to offset the energy required for 2 starts and likely just leave it in a depleted state. We're experiencing a usual frosty period now with daytime highs of 10°F or less.

During the colder days of winter, the truck doesn't start as quickly as the summer months.

I just tossed a minder onto my battery early this afternoon in preparation for another impending short trip tonight. My NOCO 2D has yet to be installed in the engine bay.

I plan to get an H8 AGM sometime soon'ish.
