Received 12V Battery Warning - Looking for some advice

[UnsungZero_OldTimeAdMan]

Thanks for everyone's help and advice regarding the 12V battery warning!

I thought I'd provide a quick update on where things stand:

Yesterday morning I used the RiDE menu to reset the 12V battery warning and it has not reappeared. I also have not experienced any issues while driving the car and have kept it plugged in the home EVSE and charged up to 80% when not in use. Hopefully, everything will be OK until I can drive over to the valley for my scheduled appointment on 3/17.

P.S. It snowed up at Mt. Bachelor yesterday but I'm not sure I want to drive up there and not be able to start the truck after a day of skiing.

While the error has not returned, something had to have triggered it. You're probably fine to travel, if you carry a jump pack. Not the little ones. The larger, lead acid ones, that can provide enough sustained power to boot everything up and make vehicle drivable. They are not that expensive at around $160.

Connect your 12V battery to a trickle charger with desulphation cycle, at least part of the time. That would likely be far more effective at keeping your battery alive (and healthy) than keeping it "plugged in the home EVSE."

There is a point in the settings to select, or de select the service mode if needed that to my knowledge does not require a code.
I replaced my 2 12vdc batteries before they went out. I suggest this is wise. Yes, 30 min. does it.

My battery was replaced this morning. It took about 30 minutes. Mobile service had a canvas umbrella connected to the R1T to protect my vehicle and parts from the rain. The only minor glitch I noticed via the mobile app was the tech left without taking the vehicle out of service mode. Good thing I noticed it within five minutes of him leaving the house. He came back and took care of it.

You can easily take it out of service mode yourself in the Vehicle menu.

I like the idea of these batteries for two reasons. First, it should be an improvement over the stock lead acid agm. Second, I don’t like the idea of paying Rivian to do something as simple as a battery replacement. Unfortunately, I got the 12v warning yesterday and will be taking it in to the service center today. Would have been nice if Ohmmu had these available now.
