That's great! Hopefully, it will last longer than the current lead-acid one.
Thanks for sharing. I heard a very fast unrecognizable word but I didn't realize it's "lithium" until you confirmed it.
he said it will last the lifetime of the main battery pack
Well there's 50lbs of the 200-300lb weight reduction on the 2021 S.
My AGM lasted over 5 yrs at $178 from Tesla...it’s ridiculous to pay $400 for a 12v lithium
you only get to hear from a few bad ones on this forum...so it’s not a good comparison of longevity

When you are in very hot states such as Arizona, the 12v battery rarely lasts 1 year. I am so happy they are going with a lithium 12v battery.

Again..this is just you reporting that it last a year....there are millions of car that run lead acid bettering for years without issue..
It’s the Tesla elite owner like you...that have *sugar* load of money that can afford a $400 battery

Which might increase the vampire drain. Lots of trade-offs. I cannot wait to find out what they are doing!

It'd be in the ballpark of 25 pounds, but yeah. I swapped the one in my 3 out for a Lithium Ion and that was the difference.
Glad to see Tesla is finally coming around to this no brainer move and now we can get rid of the problems of dying 12v batteries while also improving performance through weight savings.
I doubt it. I have a 12v lithium battery from MPP and vampire drain isn't an issue. It has full built-in BMS as well.

4+ years and 115,000 miles in interior California with summer temps well north of 100F and still on my original 12v. “Rarely lasts 1 year” is a significant exaggeration.
I imagine that the 2021 Model S Plaid+ might get a lithium-Ion battery similar to the one offered by Porsche.
Porsche Offers Li-ion Starter Battery Option
Porsche will offer a lithium-ion starter battery option for the 911 GT3, 911 GT 3 RS, and Boxster Spyder.
The 12.8V, 18 Ah lithium iron-phosphate pack from Gaia weighs less than 6 kg (13 lb),
the new battery is more than 10 kg or 22 (lb) lighter than a conventional 60 Ah lead battery.
Porsche says, its starting capacity is limited at temperatures below 0 °C (32 °F) due to its specific features.
Porsche’s new lithium-ion battery will be available as an option delivered with the car,
selling at a price in the German market of €1,904 (US$2,900) including 19% value-added tax.

I have not pulled them out and weighed them but the 12V battery on our S seems to be about 1.5 times the volume of our 3.
Just this week we had the 12V replaced in our S at exactly 18 months since the last and near San Jose we have a much more moderate climate than the desert interior.

May I ask when you put the Ohmmu Li battery in, and was there any reprogramming etc needed?
I replaced mine at 3 years and 5 years. It has been my number one repair. So - give me Li.
In my area, 3 years is MTBF for ICE cars. Certainly interior CA is worse.
There are many Teslas that burn through them more than every 3 years. Wonder if there is a good pattern like certain years or excessive vampire drain like high temp protection, sentry mode etc.
