12V Battery Replacement Megathread

[freshpow]

Was seeing what DuoRivians went with, battery wise.

I am in your boat. Update and 1 week later..."Battery Issues". I am just leaving it plugged in at home. But will probably need to fix it prior to selling it.

My battery warning popped up last month and I managed to go a little over 3 weeks without any issue, but made sure to keep the truck plugged in to my wall charger whenever possible. A little after 3 weeks, I got turtle mode and a number of other error codes. A hard reset got rid of all those error codes for the time being, but I figured that meant it was finally time for me to replace the 12v. I replaced with the Ohmmu Sodium and all good so far. I expect the Ohmmu battery to last a lot longer than the OEM. I only got about 2 years out of this last one from Rivian and don't care to pay $500+ every couple years for something that is easy to DIY and much cheaper.

A quick battery test on the OEM 12v I removed confirmed that it was indeed cooked.

I tried a 12v repair with my NOCO Genius5 but that only made it worse.

If anyone is looking for a single Ohmmu 12v, I have an extra one for sale here (ordered 2 but only need 1).
