If and when the car is out of warranty would it make sense then to replace the battery with a Lithium battery instead of a lead acid? https://www.ohmmu.com/product-page/12v-lithium-battery-for-tesla-model-s

I think at the time I had it done it was $250. My two Model S were both CPO though and still under warranty so the bill was $0 for me so I'm not 100% but I believe that would have been the cost at the time.Great info. Thanks!
What does Tesla charge to replace the 12V battery past the original 4 year warranty?
Follow this:
- Car runs many systems from 12v battery
- car normally charges 12v battery from traction battery propping up a dying battery
- car stops charging traction battery below 20% of traction battery
- marginal 12v battery runs down before traction battery runs down
- car dies
The traction / high voltage battery supplies power to the 12v subsystems while the car is underway until it is at 20% at which time you're left with only the 12v battery alone running all the computers, fans, defrosters, seat heaters, displays, and other "accessories".
This sounds completely and unabashedly 100% totally made up.
HA, you'd think engineering could solve that problem on a $50K+ car, let alone a 48V cart. Really, the $10 digital voltmeter installed tells you exactly how much voltage you have left. Experience golf cart owners know that 48V carts generally have about 50 - 51V at full charge and never let it get down below about 48.xV at rest. Simple, eh?
Sooooo... My wife and I took a short vacation to Las Vegas this weekend. About 10 miles from our hotel(30 miles left in the tank), my car showed that it was starting to shut down and I needed to pull over in a safe place! I still had 12% power left. It also said that I needed to replace my 12 volt battery. Has anyone experienced a shut down when you still had power left?
Should a High Voltage Battery Heater issue cause the vehicle to shut down on a day in the upper 50s?
Why would the battery heater shut down the vehicle when it's not cold? And why would the 12v battery die and be unable to recharge with more than 30% on the HV battery?
I had this happen: car dead in garage (wouldn't turn on). Mobile service looked at it remotely and said it needed to be looked at by a service center because of a fault isolating the HV battery. Suggested that I put a trickle charger on the 12 V while arranging transport, which I did.If it is a high voltage fault the car can't close the contactors to pull power from the battery so it has no way to use the power in the HV battery.
According to Tesla Service, no faults, just a bad High Voltage Battery Heater which may have caused the 12 volt battery to fail. No one seems be able to explain why this would cause the 12 volt battery to fail. Basically a really easy fix if your mechanically inclined but Tesla doesn't allow the owner to find out the problem without in my chase towing to the Service Center. I was quoted $1200 for what I could repair for less than $200. (Don't forget that towing from my driveway 2.5 miles to the Tesla Service Center costs $250, after being quoted $125.) I thought I would be able to access the logs but after going through a couple of departments at Tesla, I am informed that logs are only available to owners who have been involved in an accident and only regarding the accident. I know I'm out of warranty, but this seems kind of nuts.If it is a high voltage fault the car can't close the contactors to pull power from the battery so it has no way to use the power in the HV battery.
