12 volt concerns

[ajdelange]

I'd believe the manual over hearsay.

Believe your eyes. They clearly have 6 cells.

You are able determine 6 cells in the photo I posted, or another photo? The red covers are electrical safety guards, different size and shape on each battery. Not sure how that is indicative of number of cells.

I lean in the direction that they are 12v batteries, but I accept the possibility that they are 6v.

PUT THE NAIL IN THE COFFIN. IT'S 2 12V BATTERIES, LADIES AND GENTLEMEN.

I don't understand this but okay.

I'm literally posting this from my frunk.

Awesome, thanks for clearing that up!! Deep Cycle Batteries.

2nd pic are fuses.

I couldn't*** get the top off the left one, or a side shot of the right one.

I’ll believe the label on the battery

Looks good: Electric vehicles - C&D Technologies, Inc (cdtechno.com) ...seems Tesla uses C&D batteries as well.

On the topic of 12v batteries, I had this warning light come on today
I was en route to an appointment and continued on for a few miles. Left the truck for about 30 minutes afraid I was going to be in trouble when I got back in but the battery icon was gone.
I called Rivian service before departing and they stated the icon indicated a detected difference in voltage between the two 12v batteries (?), that a sleep cycle while I had been away from the vehicle resolved the issue/cleared the message, and that it was nothing to worry about. I gathered that I was not the first to experience this.

12 volt batteries have always been the most common point of failure in ICE vehicles...hence the ubiquity of jumper cables and portable battery jump chargers. 12 volt batteries usually last a while and then, poof, they don't work. Sometimes failure is fairly quick. The 12 volt in my former Ridgeline died not long after I bought the truck and had to be replaced. My Kia Niro EV notes that if, for example, the headlights are left on, the 12 volt may run down and the battery may need to be jumped or charged before the car can be used. In the case of the Niro, there is a way of getting into the car with a key if the 12 volt battery dies...the R1T needs the via the port near the hitch receiver before being able to get in the car. In all my vehicles, including the Kia EV, I have kept a jumper battery/cables to use as necessary and kept this plugged into a 12 volt socket to be ready. That won't work in the R1T since I won't be able to get in to access such a unit...not a problem if I'm home, but could be a bummer on a trip. Take the jump starter into the tent/trailer/b&b, I guess.

Rivian issues/concerns:

1. Is it possible to wear down the 12 volts by keeping the lights on, for example, or do the 12 volts recharge from the main battery continuously? In the Niro, the 12 volt recharges when using the main battery only.
2. I assume that the 12 volt batteries are generally recharged by the main battery when the R1T is in use but have not caught that in the manual.
3. Is there a detailed guide to getting to the 12 volt batteries if (when) they need to be replaced? If so, please link.
4. Can the 12 volt batteries be user replaced as can be done in an ICE vehicle or is Rivian service required?

I know this is, I hope, way premature for a truck I've had for less than a month, but, well, better to find out now than be questioning in a crisis...

Thanks!

You can jump it.

Seldom do they fully die.

Hopefully rivian computer monitors them and tells you when they're low.

The rivian has 2.

If you're worried, replace them proactively every 3 years.

I've had lots of batteries, but the only time I've been stranded is when I ignored earlier signs or it was five years old.

You're a fool! They CLEARLY put the wrong label on that 6 cell 6 volt battery. ???

Never been stranded...always ready for a jump, though...it would be nice if a future OTA update would monitor the 12 volts...don't see that in the current software.

It's FUSCHIA!!

Is it normal for full EV to have 2 12 volt batteries? That will be a pricey replacement.

This isn't unique to EV, even my ICE Volvo has 2 12V batteries (one for start/stop system and one for everything else).
