Title says it all: Model S March 2015 build, currently at 99k miles and we are on our original 12V battery. I don't want the car to strand or inconvenience anyone with an unexpected 12V battery failure so I'm wondering if I should just proactively replace it now?
I know the car is supposed to warn of an impending 12V failure but I've also read that those warnings sometimes do not occur, so I'm hesitant to put my faith in a warning that may not happen.
Part 2 of the question is how should I go about replacing the battery? I see three options out there:

Part 2 of the question is how should I go about replacing the battery? I see three options out there:
- Make a service appointment and just pay Tesla to take care of it.
- Replace it myself with a lead acid equivalent to what Tesla would use.
- Replace it myself with a Li-ion 12V battery from ohmmu,com.
Opinions?
