@atpfm YoLink products have proven to be very helpful for tuning my HVAC (w/ claude.ai opus 4.6 assist).

@marcoshuerta If you're referring to the part where I asked @caseyliss to consider how much "replacing the battery" would cost on a Taycan, I meant the (tiny) 12V battery, not the car's giant battery pack.

@siracusa @marcoshuerta FWIW I legit thought you meant the main pack

@caseyliss @siracusa @marcoshuerta If you replace the main one, I'd expect them to throw in a change of the smaller one too. $$$

@caseyliss @siracusa @marcoshuerta I totally knew that John meant 12V and could tell nobody else picked that up

@caseyliss @marcoshuerta Probably because you’re thinking, how much could replacing a tiny 12V battery cost? I dare you to look it up.

@siracusa @caseyliss @marcoshuerta having had to buy a couple in recent years (and watching some car builders on YouTube), I know the answer is “an upsetting amount more than you’re expecting”, regardless of currency

@WTL @caseyliss @siracusa @marcoshuerta Eh, with Porsche nothing is “thrown in”. Unless you count additional lines on the invoice.

@siracusa @caseyliss I got curious and looked it up. That had better be one hell of a battery!

@siracusa @caseyliss @marcoshuerta having replaced a 12v battery in a Macan Turbo I know I saved > $500 off dealer cost by borrowing a programmer from a friend to register the new self installed battery.

@siracusa @caseyliss @marcoshuerta I did. Wow.

@siracusa @caseyliss @marcoshuerta BMWs only fault in this is the non-standard posts they use. But you can easily add them to a normal 12V when the time comes.

@sjtrny @atpfm yup seemed like @marcoarment was saying Daikin was some cheap brand, I was astonished because in Australia it's the top performer, both in efficiency and reliability.

@siracusa @marcoshuerta @caseyliss The issues most folks had were around early software issues that drained it prematurely. I have a trickle charger I bought off Amazon just in case, but I don't typically let me car sit for weeks without it being turned or at least plugged in. After 5.5 years, mine shows 13.5-13.7V in regular use. Ironically, our IONIQ 5 had the same software drain issue…hence, the trickle charger.

@atpfm @caseyliss I’m still in love with my 2018 BMW. Yes, I’ve poured money into it, but the newer cars don’t provide the same locked-in driving experience.

@atpfm i4 is a nice car, although it does suffer from being, essentially, an ICE car. It even has a tunnel!

@trentstevens
Yeah unfortunately it seems like battery registration really does make a difference in longevity.
Our model 3’s 12v is lead acid so it was $89 at the service center (cheaper than Autozone!). It would have been just $125 to have mobile service come out and replace it!
But all our other cars have AGMs and 2 of them require registration. Thankfully I’ve never had to replace one.
@siracusa @caseyliss @marcoshuerta

@WTL @caseyliss @siracusa @marcoshuerta and deny you the opportunity to create a personal relationship with the service department? Perish the thought…

@atpfm @caseyliss Can’t wait until ATP discovers BMW ‘Neue Klasse’ and the firestorm that will follow. (Deutche edit)

@wktenbrook I am very aware already.
