No, it doesn't make any real world difference but cars are designed around the standardized emissions test and saving 5 CO2's in the test can make your car substantially cheaper in some markets. It's mostly there as a result of start-stop systems putting a higher demand on the battery.
The car's battery management keep tracks of battery age, cycles etc to optimize the charging pattern of the battery (bit like a smart trickle charger vs an older unregulated charger) and it needs to know if the battery is changed so it can reset those adaptations and know the correct capacity etc. The car will start just fine if you don't reset the registration but it will hurt battery life because it'll try to compensate for battery wear that isn't there yet.

It's been on many German cars going back to like 2000, earliest car I had that needed it was an E60 5 series. A scan tool is every bit as necessary as a wrench or screwdriver if you want to do much of anything on a modern car. Shit's complicated in all sorts of ways now.


Interesting, I guess. It comes down to knowing your vehicles then. I vaguely remember the controversy around the stop/start system before, but never looked at how prevalent it is or what it all entails because I've not looked at or owned a vehicle that had it. From a quick refresher read, it sounds like a shitty system for locations that don't need it and is just another reason to keep/buy older cars (or sports cars that don't have it). With the main complaint that it puts more wear on the vehicle's engine and starter, in order to save a negligible amount of emissions that don't matter to anyone outside of California (in the US). I try to drive all my vehicles until they die, so I would actively look for vehicles that don't have it (or can permanently disable it), if I was buying something.

Without looking every vehicle up, for US manufactures, these feature are not on very many trucks until around 2019, nor on most of the V8 sports cars I saw. There are rumors the Mustang and Corvette might be getting the system this year. Strangely enough, the 2016+ Cadillac CTS supposedly has it, even though it has the same engine as the Corvette.

I also read that many manufacturers have or are starting to put in the ability to disable it, some temporarily with a button in the cab and some permanently through the computer. Dunno if it would effect how the system fucks with the battery though.

Furthermore, if I can buy a different battery than recommended for my car (but still fits, with close to the same or better CCA), for $40-$50 less, I doubt the stop/start inefficiently charging it would make it die fast enough where it's still not a better deal. For like half this forum, the Texas heat combined with the battery getting boiled sitting in the engine compartment kills batteries faster than normal anyway, so there is more value on saving money up front, instead of on the back end (for daily driven vehicles, at least).

Nothing like a little curb rash on new car with ~1000 miles on it. No more sport/lower profile tires for the wife.

Owch, looks like it's time to get her some curb finders! I just looked them up to post a reminder of how silly they look, but saw some modern ones that don't look too bad. I would assume, if they regularly get hit on curbs, it would need to be replaced every so oft:

The car itself may be a bit ugly, but I would think you could get such a set up for a wide range of cars, or maybe even make some yourself.

Also, I've been driving sports cars my whole life and I don't recall ever getting curb rash... and then the first month of owning my current car, I had a little brush. Very minor damage that only shows when close, but still.

If it makes you feel better, the teen daughter smooshed the gold Model S into my white S. Hers buffed out fine of course... lol

Women drivers have been fuckin me up these last few months
/Too soon?

I have a good 8 years until I have to worry about teen drivers. Of my daughters, I think the older one will be a more skilled driver; pretty good at self-correcting behaviors once she has the rules down. The younger one is much more DGAF/YOLO.

My middle kid backed my model S into the side of the garage trying to exit the garage a few months ago. Tore the drivers side mirror off and somehow also hit the front fender.

Wheels are fine at least!

So as wrap up/follow up to the battery saga...

After multiple places looking like I was asking them to do A2M when I asked about replacing a battery that was in the trunk I got a new battery and decided to do it myself. Watched a few videos that also made it sound absolutely torturous. Pop the trunk open today expecting to spend an afternoon wrestling with nonsense..... and done in 30 minutes. Hardest part was clipping back on a cosmetic screw cover on one of the D rings that hold the cargo net in.

(New battery in before I buttoned it in and reconnected it)

Get the old battery out and take a good look, and it has something I have never seen on AGM batteries before (although admittedly I haven't worked with a ton of cars that use AGM), that being... what looks like servicing plugs/ports :

So I might get out my old acid/water specific gravity checker and maybe do a "maintenance" on it and see if I revive the old battery. If so, I guess I'll have a spare.

Uhhh AGMs I think are supposed to be sealed on purpose. I would double check that battery part number and see if there's servicing instructions.

I'm going to dig in on it some. I know the new one is wholly sealed and "non servicable", which is what I'm used to.

Just seeing those plugs, and seeing one with some obvious corrosion/sulfurication around it was something I am used to only seeing on ones you can service.

One little bit that snuck up on me. AGM batteries are usually ported to be able to offgas safely, for a battery in an enclosed space like a trunk that means you have to attach a little venting hose to a port on the side of the battery. New battery was ported on both sides, my car only vents from one, so I had to pull a plug off the old battery's unused side and plug up the new battery on the positive side.

But it was easy enough I have a "crochety old man" urge to go back by those places and tell the techs there that they're little bitches.

Plaid? What did that poor car ever do to you?!? Er... um... I mean, congrats on the old man seats!

You should have just bought a Vette, they come with old man seats from the factory (not in plaid though).
lol, tartan. And it’s a traditional style for the brand.

My GF has the same exact little back pillow that your wife has. I had the same car, different color. GF puked in it. I put almost 200 miles on it before I sold it. Average speed was like 29 MPH....all except for the last 20 miles. :D
Haha, that's hilarious. Yeah, the small pillow came in handy a few times. I even used it when I would drive alone, which was most of the time for that car. Now its being used on as a foot cushion when I put my feet on the coffee table.
