What type of battery does the ITS have? AGM?

[optronix]

Called Acura roadside assistance, they sent a guy out within 2 hours (was busy with work, was actually probably about an hour), and got it running with a portable jump starter. I left it running for about a half hour, started it up an hour or so later and drove to Best Buy and back, and it's been fine since.

I'm still wondering how the hell the battery went completely dead so quickly and without warning... yes I have been letting it sit for most of the past few weeks, but I did drive it less than a week ago and like I said I've done this with other cars in the past where I'd let them sit basically all winter and only start them/take them out when the weather went above 50 degrees... so rough estimate about once or twice every 2-3 weeks. Never had any issues, to the point where the overpriced maintainer I bought never saw any use.

I bought another portable jump starter as the one that I found in my garage was very, very dead having been completely forgotten for at least 4 years. I'll also probably buy the pigtail adapter for my Porsche/CTEK maintainer. If it acts up again in the next few days I'll get it in to the dealer.

Weird, and not a fun experience.

You can Get the CTEK pigtail with both round fittings to go under the pole connection nut, and regular alligator clips. I like the clips better since you can easily change between cars.

Any chance your fob was close enough to activate interior lighting, etc., at various points?

I got the predecessor to this guy about 6 years ago and it has been rock solid on my racecar. It sits plugged in for about 325 days per year, slows charging above 80%, stops when it gets to 100%, and will maintain without issue.

There are a lot of tenders/maintainers out there that work fine. I made a mistake years ago with a boat, and left a "trickle charger" plugged up. It trickled the battery to death!

No, can't see that happening. Fob goes on a hook on the fridge, through multiple walls and ~30-40ft away.

2024 ITS with 4000 miles. I was out of country for three weeks and kept the car in an indoor air conditioned garage. The battery was not completely dead but could not crank with only 10.6V. Never happened in my previous cars.

Yeah I went ahead and ordered the cable adapter for the maintainer I have. I'm scared to leave my car without starting/driving it for 2-3 days now. And yes I went through and checked if I "left anything on"... nothing out of the ordinary there, at least as far as I can tell. I've done nothing aftermarket-related in that category either. All I've done to the car since buying it are wheels and springs.

Not sure if there's any validity to this, but these issues could possibly be because the Type S doesn't have an auto-start feature?

Seems to me that the auto-start feature would put more stress on the battery, so I don't think that its absence could be contributing to the problem.

You mentioned having installed springs. Was anything done to the adaptive damper system, which is electronic?

Correct, so my hypothesis is that cars with this feature have stronger batteries to account for the auto-start feature. The ITS does not, so it may have a weaker battery, or maybe even faulty from the factory because it may be specific to this car and may not have gone through as much QA. Just a thought, I'm not suggesting it is this way or not.

edit- did just a bit of research here, there may be substance to this. I know parts sites are not great for documentation but there are definitely different batteries listed for the base Integra vs the Type S. For any battery experts out there, the only true difference I can extract (other than cost- ours is cheaper for whatever that's worth) is that one in the base cars is labeled as "EFB" and the one for the Type S is not.

base Integra

Type S

No, just literally swapping the springs. Everything else was left as it came from the factory. The chance of a springs install having anything to do with draining a battery is infinitesimal.... at least to the point I don't want to think about what troubleshooting would look like.

I'd bet a bad battery. Probably one that just sat in a factory yard for a year or more.

From what I've seen of this car, I'm starting to think a lot of them were just sitting at a factory yard somewhere while waiting for certain parts. I suspect that's why my brake fluid was so gross and why a brand new car had so much dust caked into certain body panels.

Mine lives outside. No issues sitting for 4 days in 10 degree weather. Started right up. Tomorrow it will be -5 so I'll let ya know if there is a change

I've learned that a good battery maintainer is a sound investment. Most modern cars are hard on batteries, and there are more bad batteries out there than I would have guessed.

On my gti, I enabled a setting in the registry for "long fob range". Oh it certainly improved range! I could reach it at the end of a super target parking lot if I flipped out the switchblade key to act as an antenna and raised my arm.

After 5 years I had to swap the oem car battery and my fob died every 9 months because the car and it were constantly "talking" . Problem solved by putting the fob UNDER my rfid blocking wallet, but no joke that modern cars draw a lot, even when sitting and doing nothing. Our audi cycles fans, pumps, valves, and even an auxiliary heater just sitting there... It sounds like a decepticon .
