Poll: How many are still using original 12V Battery that came with the car?
- Thread starter Resist
- Start date
The poll didn't put a bound on the Model Year, so a 2017 Model 3 owner still using the original battery is a lot different than a 2023 Model 3 owner still using the original battery. The poll would have been more useful if it was polling for the Model Year (If you are still using the original battery, when was your Model 3 made?).

I was wondering about that. Can I have Tesla come and do it via a mobile service call?
Tesla 3 RWD 2020. I want to change the 12 V battery as a preventive maintenance.
Please guide.
Thanks

If you are within Tesla's mobile service area, contact them using the app and have them come out to you to swap the battery. Should be in the range of $120 or so. If you are the DIY type, you can still get the battery delivered with mobile service (or buy it from a Service Center over-the-counter). Under the frunk there is a plastic panel near the base of the windshield that pops off and the battery is right there. I believe that the procedure also involves disconnecting the high voltage plug under the rear passenger seat prior to removing the 12V battery.
Really, it's worth the cost of the extra $35 for a service tech to do it. I had my battery proactively replaced when it was almost 4 years old. No problems with it; just wanted it done before leaving on a trip. Since it was a replacement requested by me and that the battery was still "good", they left the old one with me and it's still sitting in my garage. Probably run down by now and I'll have to deal with disposing it in a proper manner.

towed to SC and being repaired as I type. Battery warning seems to be worthless.
After reading enough about getting 'bricked' I replaced my 12v battery yesterday to be proactive. The old battery was original 7/18, just over 5 years old. I figure I got my money's worth. Initially they brought a 'new' replacement dated 8/22. I refused it and asked for a newer manufacture date. Yesterday they put in a 5/23 manufacture date. House call for $271 all in.

Hopefully you got more work done than just the battery swap for that cost. Mobile service has appeared to charge about $130 from the reports I've read here. That was what I paid a bit over a year ago.
