Some Lucid Air Owners Learn To Jump Their 12 Volt Batteries

September 6, 2022

To preface this post, I find these quirky and odd situations fascinating, so I do love to cover quirks, which is why I am writing this.

In short, I see more and more issues pop up randomly from Lucid Air owners around their 12-volt batteries. I am not sure if this is a large issue or not but it does seem like I see the issue come up more than most other issues.

Sometimes when there is an issue with the 12-volt battery, the car simply won’t drive. So Lucid Air owners are looking for ways to “jump start” their 12-volt battery so they don’t have to wait for a Lucid Air service rep to tow their car to a service shop and have the battery replaced.

A thread in the Lucid Owners Forum has some Lucid Air owners discussing ways to jump the battery.

The 12-volt battery, at least one of them, is located behind wheel liner of the rear passenger wheel well. There are wires you can possibly get to, I don’t recommend you do this yourself, but if you want to, here is a diagram:

Here is a photo from the forum of someone who had their 12-volt battery jumped using a secondary battery of some sort. I don’t know much about how this works, so I am obviously dumbing it down, because I am dumb when it comes to this stuff:

One Air owner explained “That picture is great as it answered my “where was that pigtail attached” as I knew it could not be allowed to just bounce around in the wheel well. Note the positive (+) wire you need to get to may not be red, in my pic you can see it just has a piece of red shrink wrap on it. you may not need to get to the negative (-) side as any well-grounded unpainted metal should do, but not being absolutely sure of Lucid’s ground system it may be a good idea, however, in my case it appears the ground (-) side is still in the wheel well. There is no real risk of electrocution from 12V, but using care is always a good idea.”

Your vehicle has two types of batteries; a high-voltage lithium-ion battery pack that powers the electric powertrain motors and two 12-volt AGM batteries that power your displays and safety systems. When you plug in your vehicle to charge you are charging the high voltage battery pack.

Again, I don’t recommend you do this on your own.
