I just installed the Full Throttle battery and am still getting the 12V battery warning. Performed both resets on the center and driver displays as well as waited about a half hour in case it was a charging issue. Does Tesla need to reset something?
I got that with my car. I went through the menu on the MCU to shut down the car, then I removed one terminal from the battery, waited a few minutes and hooked it back up. The first time I didn't shut down the car through MCU and it came up in a state that didn't clear the message. The second time the message cleared.
I have the service manual and it does not say anything about different battery configurations. In the instructions for replacing the battery, it just describes the physical removal and replacement no mention of a need to reconfigure anything in software.
Sure does:
Installation
Installation procedure is the reverse of removal, except for the following:
- Ensure that the HVAC intake drain diverter is positioned properly when reinstalling the pollen filter front housing.
Caution: Take care not to damage component(s).- If changing from an Exide to a C&D battery, update the vehicle's configuration with Toolbox.
- Connect a laptop with Toolbox to the vehicle.
- Select Views > Vehicle Configuration > Vehicle Configuration Update.
- In the "12V Battery Type" menu, select C&D.
Another data point..
Got the alert on my car. Communicated to both mobile tech and another tesla rep that contacted me when I initiated the service through the app. Conveyed I wanted to purchase the battery from parts and do self install. Both said would be fine. (I like doing the work myself and also save $$ from the labor cost).
Drive over to tesla and just as I'm about to purchase ask the parts guy if I need a software update for the battery. (going from the C&D red top to the Atlas yellow top). He goes back and talks to the tech and comes back and says yes I need that update and so I can not do a self install. His explanation was because its AGM battery. Though I believe the C&D is also AGM so I'm not sure what this config does differently. So ended up having to pay out for the installation from tesla.
How much did you end up paying? I have mobile tech coming in the couple of days to replace my 12v battery. Came out to $214 after taxes. Labor was $39.
I received my 12V battery warning last week. I decided to go with the Ohmmu battery to see how it handles my upgraded sound system. Typically I just let someone else to my installs however, with this social distancing I gave it the ole college try. Fortunately for me the replacement/install process went smooth. I think it was about 90 minutes to finish the project. I just took a couple of pics. No issues with the warning staying up after install and did a "battery" of tests that came out sat.
Nice. Labor for me was $53. Total $229 with tax. What is your service center hourly rate? Mine is at $175.
Nice. Service center hourly rate is $195. I'm in the DC Metro area. Do we know what brand they use for the battery? I googled the part number in the invoice and different brands came up.
My guess is you just got a bad battery. The situation seems to have improved over the years, whether due to improvements in charging algorithm or better batteries. My first battery lasted about 2.5 years (11/14-3/17), the second battery is going strong since 3/17. My car was in the service center for a bunch of stuff recently and I asked if we should proactively replace the 12V. The service advisor wasn't concerned - "not worth it; wait until you get the warning." When the first one died, they said you should have a few/several weeks until it becomes serious.Folks, I decided to post this here since there is already a thread going about the 12v battery, but happy to start a new thread if that is better. In any event, my model S is only 15 months old and has 20,000 miles on it and I received an error message today that the 12v battery needs to be replaced soon. I've scheduled service to get it replaced, although they cannot get to it for 13 days. I find it inconceivable that a 12v battery would need to be replaced every 15 months. Thoughts?

Uh, well, you have the thinking backward on this one. When the car is on and being used, that is when the main battery is connected and the DC to DC circuit is active and keeping the 12V battery topped up, which is easier on it. It is when the car is sitting and unused that it is draining down that 12V with all of the minor computer vampire usage, and the 12V gets drained and refilled and drained and refilled, etc. etc. And that the more wear-intensive kind of condition for it.It also would be nice to know if it is better to keep using it, causing it to charge/discharge, or better to let it sit and get cold.
