Is it worth it to upgrade regular 12v battery to LITHIUM 12V BATTERY from OHMMU ? It is not cheap so does it make any sense to do so?

Wut!!! Many people are on 2nd and 3rd batteries with in 2-3 years.Probably not. There were a batch of early failure 12V batteries a year or two ago. But that’s been it with Teslas.
Otherwise, the things that kill, “normal” 12V batteries lead-acid batteries, like repetitive high currents in cold weather (starting an ICE motor, which the Tesla doesn’t have) or deep discharge, which can happen if a car’s battery charger fails (not that uncommon with an ICE car, very rare with Teslas, since the 12V battery charges from the ever-present traction battery) don’t happen. The 12V in a Tesla just tends to run the low-voltage electronics, like the radio and computers. Hence, the thing tends to last forever.
So, no point in putting in some purported high-performance battery; save your money and spend the cash on something that really matters, like mud flaps.

Odd. Got a 2018 M3. 12V battery got replaced when the pyro fuse blew in early 2019; been working fine since then.Wut!!! Many people are on 2nd and 3rd batteries with in 2-3 years.

I am worried more that the Tesla Battery Management SW may not be suitable and optimized to handle a non Tesla OEM battery.Wut!!! Many people are on 2nd and 3rd batteries with in 2-3 years.
Is your car in warranty? Tesla will replace as often as necessary for free, probably in your driveway or work parking lot. If your car is not covered by warranty, the analysis is made somewhat more complex. The 12v has been replaced twice on my X.Probably not.

I have a 2019 I bought new from Tesla. I received a 12V battery failure warning on my display about 6 weeks ago. I called for mobile service and they replaced the battery the next day at a cost to me of $165 for the battery and $75 for labor. Car was still under warranty and I advised I thought the battery was covered and had read where others had been replaced at no charge. Technician called and double checked, but no joy. Considered a wear/tear or consumable item and not warranted. No mention of 12V battery in warranty, implicit or explicit.Tesla works with its numbers and that is why it is switching to 12V Lithium battery because it is tired of servicing lead acid batteries, including towing, during new car warranty.
Mine has been replaced twice. Paying for it never even came up. Even the early quote you have to approve was for $0.00I have a 2019 I bought new from Tesla.

Ha. ET vs. AT. I still got the collection of stuff that has that patch on the side, two chevrons down, from a mere (counting on fingers) 45 years ago@Tronguy : I noticed your avatar. Looks somewhat similar to mine.
If you drive the car often then the 12V battery doesn't work as hard as the one in a car that mostly sitting for a long period of time.Odd. Got a 2018 M3. 12V battery got replaced when the pyro fuse blew in early 2019; been working fine since then.
