The Tesla 12V battery, i.e. the low voltage battery, is covered under the Tesla 4 year/50k mile standard limited warranty.Why $0 ?Is the 12V battery under warranty and for how long?
It seems to be a general problem for all modern EVs (and maybe modern cars in general). When old-fashioned cars are off, they are OFF. There's virtually nothing drawing on the 12v. Modern cars have entertainment systems, cellular modems, security systems, preconditioning, etc... all draining the 12v during the "off" time. 12v lead-acid batteries like to be kept at a high level of charge pretty much all the time. The more they are cycled from high to low, the shorter their lifespan. Also, the electronics in these cars can get into weird states when the 12v battery is drawn down to very low voltages (think 6-7v), so they may refuse to start or just have odd symptoms when that happens.I believe that there is some sort of issue with the lead-acid batteries (or possibly the charging system?). I've never had a new vehicle eat through batteries as quickly as my Model Y does. The original battery lasted almost 2 years, which I think was good/standard (1st battery was replaced under warranty). From there the battery longevity has taken a dive. The replacement battery lasted about 1.5 weeks (2nd battery also replaced under warranty). The third battery is now dying and needs to be replaced (I assume it will be under warranty, it lasted 5 months). I'm now waiting for battery #4...and the car is just over two years old. No "accessories" on the car that use power, it's always garaged, and driven somewhat regularly, not every day but a few times a week at least (less than 19k miles).
On the outside of Lead Acid or AGM battery it said charge max at 14.4 V. when I first have tesla model 3. I use the Multimeter and the digital plug in cigarrete lighter both said it charge over 14.6 or 14.75 most of the time. I trade in model 3 that has so much problems all over. Wheel bearing sound, seat sound squirt every time get in or out or make a move on the seat. door handles, ... knock sound at pot holes made loud sound during charging etc they . for model Y cost me more because I bought the M3 65,204 2018 with Silver color + Auto pilot add on. Trade in lost 30,204. they buy back 35,000. Tesla is not cheap to fix any parts and tesla Kearney Mesa in San Diego, CA service is very bad, damage my MY during replace the High Voltage battery at 1200 miles but refuse to fix it.I believe that there is some sort of issue with the lead-acid batteries (or possibly the charging system?).

My experience, at 22000 miles was very similar. Requested new battery through app, expecting to pay for it. Done at no charge. From what the tech told me, the battery did not test well to them, and had prevented the a/c system OTA update/recall, which he did in my driveway.I had Tesla mobile service replace my 12V lead-acid battery. Scheduling was through the Tesla App. I selected a day and timespan (noon to 5pm). He arrived a few minutes after noon.
It literally took him 4 minutes to do the entire process:
I'm mentioning this because I thought they needed to disconnect the 400V orange connector under the rear seat. But he didn't; and the car seems happy with the new battery.
- I opened the frunk
- I opened driver's door (just in case)
- I turned off the air conditioning
- He removed the full-width wide plastic panel covering lead acid battery
- Using a power driver, he loosened two bolts
- Removed the old 12V lead acid battery (Atlas)
- Installed a new 12V lead acid battery (Atlas; looks the same as the old one)
- Put back the plastic panel
21,000 miles. Total cost to me was $0
The hilariously funny thing is that he didn't come in a Tesla mobile (ICE) service van. He said it had broken down, so he arrived in his personal Model S. He pulled my new battery out of his trunk and got right to work.
This was my first experience with Tesla mobile service. Gold star and absolutely fantastic in not needing to take my car to a shop; especially since I live out in the country about an hour from the nearest Tesla Service Center.

PS The Central Valley eats lead acid batteries; it was 118 last week. My ICE lead acid batteries only last for 3 years, so I don't fault the Tesla. This hot dry environment is just hard on lead acid batteries.

Yes parking mine at the airport for over a week, hot sun ( uncovered) ruined my aux 12 volt. FYI, a 2019 model under 6000 miles). I would imagine extreme cold temperatures don’t do the battery any good too?I had Tesla mobile service replace my 12V lead-acid battery.

Cold temperatures don't harm the lead acid battery as long as it is charged. Cold will reduce the cold cranking amps, but that doesn't really affect a Tesla because there is no starter motor to turn. The vast majority of early failures that I've read about happen in really hot areas.Yes parking mine at the airport for over a week, hot sun ( uncovered) ruined my aux 12 volt.

Just tried to pick up a 12v battery from the service center and they wanted to charge me $180 without installation.I got the warning last week that my 2016 MS 75D needs a new battery (first one still.) I was quoted $165 for the battery + $51 for mobile install. Looks like an easy job so if I can get one for $85 I'd probably do it myself.
I'm curious why the parts on the estimate is $165 vs $85.
Anyone got a recommendation for a 3rd party battery if cheaper/better than Tesla?
If you are replacing a battery in the S/X that may be about right. Mine was $165 while back. Try another service center for pricing.Just tried to pick up a 12v battery from the service center and they wanted to charge me $180 without installation.
Is inflation really at 100% in the last 16 months?
