12V Battery Help

[smicker]

Hi All--

1. I need to replace the 12V battery but the car is parked in a narrow stall with no room to remove the wheel & liner and I can't put it in neutral

I saw someone mention that they were able to access the battery without removing the wheel -- does anyone have any details on this procedure?

2. Can anyone recommend a replacement battery? I found a few recommendations in this forum but haven't been able to find any in stock.

Thanks!

Yes, the battery is definitely accessible without removing the wheel. I turned the steering all the way to the right, and just reached in around it. It's tight, but doable. Details posted here: 12v battery time (sigh)

For the battery I just went to the local car parts store.

TL;DR: If you want to skip to the fix.. 12v battery time (sigh)

The car should still drive with a dead 12v battery.

Hey Paul, long time, too bad you aren't living in the Bay I would help you. it's pretty tight without removing the wheel. try to find a way.

Ooh, good point.

To the OP, there may be something else going on that may seem like a 12v issue but isn't. (Thinking maybe switchpack or APS). That should take priority over the battery itself. What else is not working as expected, besides not being able to drop into neutral? You have a 2.x car, correct?

Hey J! I from Tesla after 16 years a couple months ago. The car is with my parents in PA whereas I'm in Germany. It's clear from other responses that I'm missing some information and that the car should be drivable without the 12V, I'll get more information.

This is the battery I purchased (the middle one) from Gruber. I took the wheel off, but other than being awkward, it was a pretty straight forward replacement.

Hi, if main battery is discharged you need to act quickly to do not get it bricked! I am from Frankfurt Germany.
