Electrified Garage: 2012 to 2014 MS RWD 12v Replacement 

Do you remember the error? Did it say "Unable to drive voltage supply too low"?

This is very encouraging for me to even try! Thank you for sharing your experience

@@BrenttheGreat no it said low voltage battery will need to be changed schedule now

@@abuckwitz Thanks. I ended up driving 160 miles to a service center and they are replacing the rear drivetrain for $7500+. Yikes

@@BrenttheGreat damn that's rough but should last a good amount of time

@@BrenttheGreat if I remember correctly, I think it said something like “12v battery low, change soon”. And my soon was like three weeks? Man it was a pain in my version of S. Almost would suggest just a mobile service if you wanted to save some frustration. 12v is packed right up under the fuse box and cabin air intake.

@@kodywillnauer9422 I got mine 160 miles away to a service center. They say I need a new $7600 drivetrain. Good times.

Yeah there's a reason why they went away from this design lol

Lol😂

Thanks 👍, I try.

They Won’t respond to those comments, they don’t wanna lose money. 😂

Scott, I just replaced my battery that was 7.5 years old, though I don’t know if that’s normal. I bought my battery from the Tesla service center near me for $165. Though it didn’t come with the adapter, you can easily remove the one on the old battery and reuse it on the new battery. The new battery is a DCS-33UNCR.

What’s the price difference from an oem 12v battery and aftermarket?

We actually just put one up a few days ago. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zFjyjZiXAUA.html&t= how to install power trunk kit for Model 3. More Model 3 content will be coming soon.

I lost a screw myself!

Xcube the battery we recommend in the video and is for sale in the link of the description should last 50% longer on average.

VTAnne Name pay close attention. New battery comes with different adapters.

@@ElectrifiedGarage --- I still can't find anything about an adapter for the NEG side. ~11:20 video guy says "Negative terminal can stay." Sales website states: "2012-3/2016 RWD Cars require adapter post which we include. (See video for installation with post adapter)". "Adapter post" means one, right? The POS adapter post is well explained in the video, as is almost everything else (Its a really good instructional video), but... DID THEY MAKE A CHANGE TO THE NEGATIVE BATTERY CLAMP? Or does the original Tesla clamp fit around the NEG post of the aftermarket battery? 4:38-4:40 of video has brief view of original clamp, which looks a lot smaller than the clamp shown at 17:42. This leads me to think that the ground cable/clamp is also modified.

VTAnne Name the negative terminal comes with an adapter for the battery from the manufacturer. It’s already on the battery when you get it. You don’t have to do anything additional.

dst rr unfortunately no we cannot

You can disable the internet connection but then you’re missing a lot of features.

@@markm0000 That still wouldn't disable the logging in the car. That would just make it so it doesn't communicate with Tesla's servers.

@@ElectrifiedGarage Yeah I want to avoid the unnecessary writes to memory. My car is on a lot, between driving, 120v charging, sentry mode. It's mind boggling that they didn't make the storage removable.

Did you shut down the vehicle properly before removing the 12v? Also did you reconnect the fireman's loop?

@genyat5931 what ended up being your issue??? I’m having having the same issue.

KnowOne no it is not. Model X uses a different size battery. evtuning.com/products/model-x-lithium-12v-battery-replacement this one will work for your vehicle.

KnowOne it is not. The X uses a different battery. The X is a lot simpler. It’s about 15 10mm bolts and the frunk lifts out. The battery is right there and easy to access and change.

What ended up happening?

@@BrenttheGreat i made a video about it - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JZTKfy0A-NM.html

Sorry we do not have an affiliate on the west coast yet.

U Tubota with the way the fuse block on top is made that would be very difficult to do unfortunately.

The reverse terminal version costs the same as the normal version for these batteries.

@@ElectrifiedGarage where did you get the adapter from?

Bryan Hall when you build things on a computer it easy to overlap everything. It just becomes a nightmare for the technician.
