12V Battery Replacement Megathread

So...what's the update.

All I see is these guys ($500) with the post adapters...or some of the options mentioned in the first post.

But apparently no way to reset the warning light?

I thought someone said that they were out of stock.

$500...ugh.

Anyone else getting the notice post update?

Just got my warning today - wrinkle...... I live in Puerto Rico and we have no service center here. Sooooo.....

I saw some people mention a battery tender as a way to make sure you can limp along, did that work? Willing to jerry rig pretty much anything to keep this rolling along.

I have to order batteries either from Rivian or Ommu and install them myself, period. So, hopefully I can clear the codes or whatever.

Question - if you can't clear the code but have replaced the batteries - do they function normally? I can live with that error so long as the truck starts and drives fine.

Lost regenerative braking, 1 foot driving, and stability control yesterday.

Apparently the AI Rivian reputation bots wander this forum and were unhappy about anyone posting that $1,000 for a battery is retarded.

In the cars defense...it was raining so who knows...

Anyone else on the battery issue train? Any other commercially available alternatives?

It worked for me for a few days, but that's it before I got my batteries swapped. Just left the tender leads hooked up and ran the tender wires into the frunk to be plugged in.

Funny enough, I was plugged into L1 charging at 8 amps overnight while the tender was on, and managed to get something surprising in charge (like 10%!) overnight. Normally I don't see that sort of charging on 120v even at 12amps. I guess the 12v batteries charging definitely do suck up a ton of power.

I'll add a pigtail and plug the tender in for any long parks once I have a place to charge at home again. Apartment living sucks....
