Haven't seen anyone post about this yet. The R2 has the 12V battery mounted under the rear passenger seat. The seat is really easy to lift off to gain access to the battery. Seems to be the same kind of SLA battery that's in the other Rivian vehicles, but I did not remove anything to look at it closer.

Is the battery in the R2 an AGM battery? If not, do people here plan to maybe replace the stock battery with an AGM battery maybe around the 4 year mark?

It looks like the same battery they are putting in R1 vehicles, which would make it AGM.

Thanks for sharing.

Looks like they put waterproof "blanket" under the rear cushion. That's smart thinking for those accidental liquid spills.

I'm starting to see more R2 on the road. It's exciting to see.

Nice. Shows they continued to learn from experience and consider repairability.

My initial thought was fire retardant and heat insulation.

Are there any downsides to housing a battery like this inside a passenger cabin of a vehicle that routinely reaches 120° temps? Not concerned about the chemistry for the battery’s sake. I’m thinking about effects of people sharing the same enclosed space.

I think Gen 2 R1’s have the battery in the cabin as well, but first Gen it’s behind the drunk right?

None. Because while the cabin can get that hot, this space is segregated from it and surrounded by insulation and metal. No more susceptible to heat than an 12V AGM that lives inside the engine bay of a ICE car.

I have a hybrid Ford Maverick - 12V battery is in exact same space. Ford put jump/trickle charger terminals under the hood.
Also - the Maverick battery has a vent tube that runs to the outside...

I probably phrased that poorly. I meant, is it worse for humans to be exposed to these batteries over long periods of time in cabin areas that get quite warm opposed to car batteries that sit outside the passenger cabin.

hours of relatively harmless exposure in the car add up.

I could also be an idiot.

Good question… but considering just about everything man made can be potentially cancerous… no one lives forever?

It's a sealed battery. They puff up when they start to die. They are way beyond dead already if the case cracks open. The chemical you're exposed to when that happens smells like rotten eggs, very obvious.

Usually lead acid batteries that are located in the interior have vent tubes that discharge in the event there's a rare issue. I would assume this one does too.
